REPORTS ON TRIP TO V0GTLE PLANT AREA TO EXAMIfiE CLASTIC DIKES OF THE C0ASTAL PLAIN, JUNE 21-22, 1984 h Plant Name: Vogtle 1 i Docket No: 50-424 I Project Manager: Melanis Miller Review State: OL Attached is a report of a field trip which was undertaken as part of the i VogtleOL-SERreview(Attachment 1). I spent two days with the l geological consultants for Georgia Power from Bechtel examining clastic dikes and others~ structures formed in the strata in the vicinity of the / *' Vogtle Plant. The NRC is presently fur. ding, through RES, a study of similar-appearing features known to have originated by seismically induced liquefaction during the Charleston 1886 eq. The USGS is also engaged in studies of the Charleston structures and paleoliquefaction features that predate the 1886 event in an attempt to extend the seismic history back in time to determine recurrence intervals. In view of the interest and attention to these features in the Coastal j' Plain, and the possibility of new information emerging from these studies, I thcught it prudent to familiarize myself with the character and occurrence of the clastic dikes as part of the Vogtle OL review. Many interesting structures and relationships were observed. No conclusive evidence for their origin was observed, but several features j suggested two significant relationships: (a) that the dikes were injected from below, rather than infilling from above, and (b) that the dikes }f appear often to be associated with sagging strata, possibly caused by l" removal of subsurface material, either by solutioning of carbonate, or [ . fluidized clastic deposits. It is, therefore, not clear whether the dikes caused the sagging or the sagging caused the dikes. Evidence for f ja)and(b)aboveisdescribedintheattachedreport. ? Q}.f 6 % 90 7o0 a
i ~ \\ AUG 31 1984 While there is no evidence based on current knowledge that the dikes represent a safety issue for the Vogtle Plant, it is recomended that a detailed, systematic investigation of the dikes be undertaken to i understand their origin and significance. In light of the USGS clarification of their position concerning the Charleston 1886 earthquake, it would seem prudent to follow up all potential sources of information on the geologic, tectonic or seismic history of the Coastal Plain. l t h Ina B.

- .z Coastal Plain Clastic Dikes Field Trip Report Introduction Dike-like structures are common and widespread in the younger Tertiary sedimentary strata of the liiocene (24-5 million years before the present (mybp)). They are found in the upper Coastal plain from Georgia to North Carolina in two upper Niccene formations, the Barnwell Formation and the overlying Hawthorne Formation.
The origin of the structures, primarily " clastic" dikes, but with associated faults and folds, is still not understood. They have been proposed, among other possible causes, to have had a seismic origin, possibly related to the Charleston 1886 earthquake (Seeber and Armbruster 1983), the result of subsidence, differential compaction, or infilled extension cracks in soil. The dikes have been studied by several authors (Heron, et al,1975; Secor,1979; McDowell and Houser,1983) and referred to by several others (see accompanying references). None of these, however, was a long-term systematic study to attempt to relate all the features, to determine the age, extent, and geometry. The following includes brief descriptions of observations of the f rs' day, and a more detailed account of the exposure of the second day, a'ong with photos of the described features. The attached map of the vicinity of Vogtle (Fig.1) locates the outcrops examined on this trip. Stop numbers prefixed with a numeral I were outcrops seen the first day. Stops 1-3 and 1-7 were omitted because of 1
- -..- a.. . -.- -. n.x x. u.. w u. a a-. I t i time constraints. On the second day, only Stops 2-6 and 2-7 were visited, again for reasons of time. Letter-number sets below the stop numbers on the map are the corresponding outcrop designations from the i USGS Hiscellaneous Field Studies, Map (MacDowell and Houser, 1983). Note j als) that the first three stops visited were within the Savannah River Plant exclusion area, for which we were given pennission and were accompanied by SRP staff geologist Wendell Marine. Stop 1 This was a roadcut about 8'-10' high consisting of i crossbedded gray and red sandy clay beds with thin interbeds of gravel. There was a considerable amount of gravel float on the outcrop. Yellow-buff dike-like projections about 1-2" thick from the bottom of the soil at the top of the outcrop were clearly visible. A weathered mottled zone at the top gradually changed to the narrow vertical to lov dipping projections, scme of which joined with others and ended abruptly and some,individualstructures(Fig.2a). On close examination, the " dikes" showed no sharp boundaries or distinctive differences in texture or clast composition from the " host" layer (Fig. 2b). According to the applicant's consultants, the composition of the clay in the dikes is the same as that of the host sediments, but the ratios of the two types of clay vary. The ratio of kaolin to vermiculite remains constant for all depths within the dikes but changes in the host strata downward from the weathering rene. The significance of these 2 l
--_-..u._-.-__ 3, observations is not clear, but the applicant's response to Q's concerning the dikes may provide documentation and analysis of the clay relationships. Stop 1 A short walk into the woods along an old railroad track brought us to a large, low level exposure, at ground level and a few feet above. The strata were yellow and red weathered clayey sands with some gravel stringers. Cutting across in several directions were 4" wide dike-like structures, the borders of which stood up above the host rock due to differential weathering. For the most part the dikes consisted of thin white clay (kaolin) seams about 1" thick bordered by yellow weathered sandy clay grading into a red to maroon rind or crust which standsoutinreliefontheweatheredsurface(Fig.3). Most dikes intersect others without offsetting them. Some dikes appeared to bifurcate, while some ended abruptly at the boundary with other such structures. That the clay material appeared to be intruded into the host rock was indicated by one dike with 2" thick clay that cut across a gravel bed. No gravel could be found in the dike, indicating the gravel did not continueacrossthedike(Fig.4). One anomalous irregularly shaped dike of gray clay, about 3" wide, offset a series of yellow and red layers in a reverse or thrust displacement (Fig. 5) indicating some form of minor disturbance during opening of the fissure into which the injected material was emplaced. 3
- _ ~ -... -, Stop 1 This was an unusual exposure offering a unique 3-dimensional I ( view of relations between dikes. The top surface and two trenchlike ditches at right angles to each other provided an interesting perspective oftwogroupsofdikesets(Fig.6). One group consisted of the thin, yellow-buff dikes lacking sharp boundaries, like those seen at Stop 1-1. Some are remarkably linear in geometry and cross each other in a regular fashion (Fig.7). a The other group are similar to those seen at Stop 1-2, with red rinds standing up in relief from the surrounding sedimentary material. These crossed each other, in places following the yellow-buff dikes and in otherplacesdivergingfromtheseorcuttingacross(Figs.8and9). The red-crusted dikes are mixtures of sand, silt and clay, with a larger proportion of clay in the dikes then in the host strata, according to the i consultants. An unusual feature of this exposure was the circular " blob"-like appearance of some of the red-crusted material, suggesting that in the third dimension these are pipe-like structures (Fig. 6, near hammer handle; Figs. 7 and 8, near hammer head; Fig. 9, at lower lef t corner of photo). An observation that may have some significance in determining the history of the dikes is that the north-south oriented, vertical, red-crusted r dikes exhibited crude planar or anastomosing shears within the dike boundaries. A nonsystematic sampling showed occasional pebbles within i the dikes were sheared across parallel with these planar 4 I i L
_ - -.. ~ _ _ _ _,. - - _.. _ _. - - -.. . ~. _. t 1 i features (Figs.10and11). The east-west oriented red-crust dikes and the buff colored dikes did not show this structure within them. Stop 1 The outcrop here was,a roadcut up to about 6-8 f t abnve road level. The outcrop was in a yellow sand member of the Barnwell Formation. The dikes were 1-2 in thick, consisting of yellowish clay with sand and silt and red rinds. They appear to end upwards at a weathered soil boundary, but close inspection indicated that they continue across the weathered zone but are faded, probably due to chemical weathering (Fig.12, to right above hamer head). Stop 1-Sa-This stop had some instructive features that a systematic study of the dikes could no doubt use in understanding their origin. The l l outcrop is about 3p high and consisted of three distinctively weathered units (Fig.13). 1 The strata were bowed down into a broad open syncline with a wave length of about 8m. In the axis of the synclinal trough, the upper yellow layer was down-faulted in a graben, bounded by vertical faults (Fig.15) along l which several dikes were concentrated. 1 These observations support an interpretation of a sag into a subsurface void with a 'small section of the sag (synform) dropping still further along vertical faults. The relationship of the dikes to this ttructure is not obvious. The dikes are not confined to the faults but show a concentration there. 5 L--
. - - ~., -. -..- - -. _.- . -.-. - ~.- Stop 1-6 The exposure was a large clay pit opening of Barnwell red silt. The exposed wall was about 3m high and had a few yellow clay dikes about 2-3 in wide. Two of these dikes were cut by low angle faults which offset then (Fig.16) in a reverge sense. The faults dip in opposite directions (Fig.17) and bear a similar relationship as faults at the Barnwell Low Level waste repository which were evaluated by USGS geologists. Their opinion was that these faults probably represented a possible subsurface subsidence into a depression, causing the overlying material to appear to shift upward (John B. Robertson memo dated Nov.12, 1979 in Allied General, 1980). The cause of the void that could result in such collapse may be a solution cavity in an underlying soluble carbonate unit, or removal of materiai by liquefaction. This could not be determined from the field observations. Stop 2 Because of time limitations, it was decided to visit the most extensive exposure available for the second day's trip. This was a waste disposal trench, about 300m long,10-15m high and 25m wide, dug on the Vogtlesiteabout2kmsouthoftheplant(Fig.18). This was the largest, most continuous exposure available on this trip. It showed several types of features and certain consistent relationships of dikes and structures that may provide clues to an eventual understandirfg of the dikes. The strata exposed in the trench were reported to be the Barnwell red beds. The overall structure was of a series of antiformal/synformal features (Fig.18)thatwerenoneylindricalinlongitudinalshape,as 6
~- o______.__-__.__.._.__._- ~ 4 determined by their variation in crosssectional shape on either side of the trench. That these were not classic-type folds forced by compression was indicated by two observations: (1) th'e axes of the various fold-like i { structures, measured by extending in imaginary line from identical points on the " fold" hinges or, each sidewall of the trench, were at high angles Il to each other, roughly N45E and N45W for two successive antiforms, and i (2) numerous small normal faults and graben-like structures are ] associated with the synforms, indicating extension, rather than i compression (Figs.19-26). Note the similarity of Photo 21 to Photo 15 4 of Stop 1-Sa, both showing a small graben in the trough of the synform i bounded by vertical normal faults.. These two exposures are 25 km apart, i j 'and the folds are oriented at about 90" from each other indicating that regional compression was not the cause of these folds. j t 1 As with the structures at Stop 1-Sa, these features indicate a sag-like i mechanism of strata sinking into subsurface voids. t 2 Other features observed in the trench that may be useful in understanding the origin of the dikes include the comon occurrence of dikes along 4 faults (Figs. 20 and 23), narrow dikes in one type of layer' branching out ) in another stratigraphic unit (Figs. 20, 23 and 27), arch-like structures over the synforms, similar in orientation to the opposite-dipping faults at Stop 1-6 -(Fig. 20, 21, and 28), some small thrust-like faults that may y -indicate underthrusting (Figs. 29 and 30), and a set of unusual 1 .intrastratal diapirs less than.5m in amplitude (Fig. 26), associated c with a series of normal faults.

u-a. E I i Stop 2 This roadcut, about 5m high, exposed the contact between the i Barnwell' massive red sand and the Altamaha facies of the Hawthorne j j Formation, of a mottled red color. [ [ At the southern end of the outcrop, vertical dikes in the upper unit, the i Hawthorne, terminated in a clay bed at the base of the Altamaha stratum ) and did not appear to cut the underlying Barnwell red sand. 4 l l Because of time constraints, only a cursory look at this large' exposure was possible. Discussion / The observations made on this 2-day trip provided some clues to, but no 4 j firm conclusions about, the origin of the dike-like structures that are comon in th'e upper Miccene formations of the Coastal Plain. A systematic study, involving several techniques to supplement simple visual observation, could likely produce sufficient information to resolve many of the questions evoked by these features. l !l Evidence that most of the dikes are intrusions, and not weathering l phenomena, is (1) the' fine clay centers that appear in all the units thro' ugh which the dike cuts, without regard to' lithic character of the i ' host strata,'(2) the absence of gravel in the. clay dike across a gravel layer, (3) the narrow linear dike structure which flares or branches out I i upward in strata of different composition, which -is similar to a P [ - description of known liquefaction features, (John Cox', pers. comm.) and l- -(4) the common association of the dikes with faults where faulting has ? occurred. I L 8 ?
. - ww : - -._ _ a _ = _,, p.. -w l 4..- t i Evidence that the dikes intruded from below, rather than infilled from above, include (1) the association of the dikes with synformal structures j which because of their association with normal faults and graben-like displacements suggest sagging or, collapse into subsurface voids; (2) the concentration of dikes along normal faults or grabens of synfomal l structures; (3) the arch-like form of faults and dikes over the syr. formal i i down-folds suggesting that the material found its way up weak or curved fracture zones resulting from collapse or sagging below the " arches". A systematic study to determining the origin, age, extent and mechanisms of dike formation would require microscopic examination of thin sections .to determine contact relations between the dikes and host strata; chemical and isotopic distinctions or similarities of composition between oikes and host rocks, changes with depth, etc.; possible drilling over an antiform and synform to see if the synform lies over a solution cavity of a subsurface carbonate, in which case it is possible that the collapse l could cause thixotopic clays to fluidize and.be. forced upwards. i Alternatively, if the synforms are not related to cavities in the q carbonate but overlie missing clastic or clay strata, it may be that some 1 other source of sudden loss of strength (seismic?) caused the upward ~ J injection of dikes, which in turn caused the sagging of the strata into q spaces formed by removal of the dike material. Included in the study i j should be so'me absolute age determinations by whatever isotopic, chemical, or paleomagnetic-techniques are effective in the material ij present in these strata and dikes. 4 i d 9
i Although not required or requested by the NRC, a verbal commitment was made by J. Bailey, representative of Georgia Power, to log the trench for future reference because of the important infomation exposed there. I .l l Based on current knowledge, there is no evidence that these features represent a saf_ety issue'for the plant. It.is likely that, whatever the t origin, these features are very old, possibly originating when the sediments were still not strongly consolidated. As the sedimentary strata are greater than 5 million years old, these structures would not represent a cone.ern under Appendix A to 10 CFR Part 100. l. It would, however, be prudent to investigate any possible' sources of infomation on the seismicity and structure of the Coastal Plain in the vicinity of Charleston, in light of the U.S.G.S. clarification on their position concerning the Charleston 1886 earthquake.
