Benton, County, Washington HRC Docket No. 50-397 Comments on Geology Tectonic t<odels

~

In spite of the large quantity of geologic work in'the Hanford area including the FSAR (Amendment 18), the analyses and models that the applicant V

has supplied regarding the structure and tectonic setting of the site area are incomplete.

Full written explanations of. the applicant's recent thi,nking, expressed only cursorily at the November.17, 1981, NRC/USGS/HNP-2 meeting, and clear integration of this thinking into more quantitative, accurate models of

'I the geology of the site area and its enviro~~ "are needed.

The models should be compatible with all details of the knoWn geology and,should include enough.

detail to permit full evaluation of the applicant's analyses of seismic probability and segmentation and capability of faults.

A list of "conclusions" regarding structure and regional tectonics presented at the November meeting by G. A. Davis, a consultant to the applicant, is here reproduced, for use as a reference in our specific requests

" and as a possible partial.outline for response by the applicant.

"CONCLUSIONS -- REGIONAL TECTONICS AND STRUCTURAL GEOLOGY TECTONICS OF COLlllSIA PLATEAU, FOR AT LEAST PAST 15 M.Y., ARE PRIMARILY A RESPONSE TO NORTH-SOUTH SHORTE tlING (AND A

'ROBABLE NORTH-SOUTH ORIfNTATION OF SIGMA 1)

(DAVIS).

ESTIMATES OF TOTAL NORTH-SOUTH SHORTENING RANGE FROM 2 TO APPROXIMATELY 7g (BENTLEY, 1980; LAUBSCHfR, 1981).

MIOCENE AND YOUNGfR COMPRESSIOtl IN THE COLUt'iBIA PLATEAU AND BLUE MOUNTAINS PROVIflCES HAS OCCURRED SYNCHROtlOUSLY WITH, EAST-WEST, THEN NORTHWEST-SOUTHEAST EXTENSION IN THE GREAT BASIN PROVINCE TO THE SOUTH.

COMPRESSIOtiAL DEFORMATION IN THE FORMER AREAS PROBABLY REPRESENTS AN INCOHPLETELY LINKED

RESPONSE

TO EXTENSION IN THE LATTER AREA (LAUBSCHER, 1977, 1981; DAVIS,'977, 1981; SMITH, 1978).

THE PRINCIPAL PLATEAU STRUCTURES ARE (1)

FOLDS WITH fASTERLY

'RENDS AND (2)

FAULTS OF TWO BROAD TYPES:

(A) THOSE WITH STRIKES PARALLEL OR SUB-PARALLEL TO FOLD TRENDS, 'BOTH OF REVERSE AND NORMAL TYPE AND (B)

THOSE WITH STRIKES AT HIGH ANGLES TO FOLD TRENDS, MOST IflPORTANTLY WITH NORTHWEST STRIKES At'lD A COt1PONENT OF DEXTRAL'LIP.

PLATEAU FOLD STRUCTURES ARE NOT RELATED TO DISPLACEtlENTS AL('3 STEEP (60'+)

REVERSE FAULTS THAT ROOT INTO THE BASEMENT AS PROPOSED BY BENTLEY (1977)

~

PLATEAU FOLDS ARE PROBABLY NOT RELATED TO SOUTH-DIPPING THRUST FAUl.TS THAT TRANSECT THE ENTIRE CRUST AND ROOT INTO A REGIOtlAL DECOLLEMENT THAT DETACHES CRUST FROM MANTLE AND ROOTS BENEATH THE BLUf tdOUNTAItiS PROVINCE (AS PROPOSED'BY.:

LAUBSCHER, 1977, 1981).

PLATEAU FOLDS 'APPEAR TO REPRESENT A STRUCTURAL SPECTRUM BETWEEN (.1)

PRIMARY FOLDS WITH SECONDARY REVERSE (OR THRUST)

FA'"TING, AND (2)

SECONDARY FOLDS RELATED TO INTRA-CRUSTAL THRUST-TYPE DETACHMENTS OR LESS THROUGHGOING ZONES OF INTERCONNECTED FAULTS AND KINK-BANDS (PRICE, 1980;

DAVIS, 1981; WCC, 1981; 'BRUHN, 1981; COWAN, 1981).

~

'VAILABLE DATA AND CURRENT FOLD/FAULT THEORY FAVOR tlODELS OF PRIMARY FOLDING WITH SECONDARY REVERSE AND THRUST FAULTING, FOR THE UMTANUM-GABLE MOUNTAIN STRUCTURAL ALIGNMENT (PRICE, 1980;

GOLDER, 1981; DAVIS, 1981; CO'llAN, 1981; WCC, 1981)

.0 "DAVIS,. TENTATIVE CONCLUSIONS, ll/9/81 CONT., P.

2 "8.

PLATEAU FOLP TRENDS ARE ANOMALOUSLY NORTHWESTWARD It( A SOMEWHAT DIFFUSE ZONE THAT EXTENDS tlORTHj/ESTllARD FROM WALLULA GAP AT LEAST AS FAR AS 'THE EASTERN END OF RATTLESNAKE HILLS.

THIS ZONE WAS RECOGNIZED BY RAISZ (1945)

AS PART OF '.

HIS CLE ELUM-WALLULALINEAMENT (CLfl/),.

RAW IS THE ACRONYM GIVEN THIS ZONE BY WCC(1981)

FOR ITS LENGTH Bfll/EEN THE RATTLESNAKE HILLS AND THE VICINITY OF MILTON-FREEWATfR.

"9.

THE

~ GEOMETRY AND KINftiATICS,OF STRUCTURES l/ITHIN RAW SUGGEST THAT IT IS A COMPLEX ZONE OF FOLDING AND FAULTING, THE LATTER CHARACTERIZED BY DIVERSE AND SUPERPOSED COMPOttfNTS OF BOTH REVERSE AND DEXTRAL STRIKE-SLIP.

"10.

NO COMPELLING DATA ALLOWS AN UNEQUIVOCAL CHOICE BETWEEN TWO PREVAILING TECTONIC MODELS:

(1)

CLEW (RAW) IS THE STRUCTURAL

'XPRESSION OF A BASEMENT ZONE OF DEXTRAL WRENCH-FAULTING THAT BECOMES EITHER DEEPER (LAUBSCHER, 1977, 1981)

OR BROADER AND thORE DIFFUSE (DAVIS, 1981)

TO THE NORTHWEST; (2)

RAW IS THE CONSEQUENCE OF NORTH-SOUTH COMPRfSSION OF PLATEAU STRATA AGAINST A TRIANGULAR; RIGID BASEMENT "BUTTRESS" WITH A NORTHl/EST-TRENDING SOUTHERN BOUNDARY WITH A COMPONENT OF ASSOCIATED STRIKE-SLIP DEFORtQTION (PRICE, 1981).

NO BASEMfNT ZONE OF STRIKE-SL'IP FAULTING IS'REQUIRED BY THE SECOtlD MODEL.

THE WIDESPREAD OCCURRENCE OF SUBHORIZONTAL

'TRIAE Al 0/iG MAJOR FAULTS I/ITHIN RAW (STEEPLY DIPPING STRIAE ARE ALSO COMMON) ARE SUPPORTIVE OF EITHER MODEL..

"11.

THE OLYHPIC-WALLOWA.LINEAMENT IS NOT A FUNDAMENTAL CRUSTAL BOUNDARY OF CONTINENT-OCEANIC TYPQ

'IN THE ARfA OF THE PASCO BASIN (DAVIS, 1981).

GEOLOGICAL INTERPRETATIONS (LAUBSCHER, 1981; DAVIS, 1981)

AND CRUSTAL GEOPHYSICAL STUDIES (SSS, 1980; HESTON GEOPHYSICAL; 1981)

CONCLUDE THAT NEITHfR CLEW NOR RAW COINCIDE t/ITH A MAJOR CHANGE IN CRUSTAL COMPOSITION. 'HE ANALYSIS OF NORTH-SOUTH TRENDING GRAVITY ANOMALIES THAT CROSS CLEW INDICATES THAT ANY STRIKE-SLIP DISPLACEHENTS THAT. thAY HAVE OCCURRED PARALLEL TO CLEW CANNOT HAVE EXCEEDED TWO OR THREE KILOMETERS (WESTON GEOPHYSICAL, 1981);

THE ANALYSIS DOES NOT DEMONSTRATE THAT STRIKE-SLIP DISPLACEMENT HAS OCCURRED.

MIDDLE MIOCENE BASALT FLOWS AND DIKES (CA.

15 MYBP)

AND HIGH-ANGLE FAULTS (ItlCLUDItlG THE HITf FAULT) ARE NOT DISPLACED ALONG THE TRACE OF THE OLYMPIC-WALLOWA LINEAMENT AS DRAWN BY RAISZ UP THE SOUTH FORk OF THE WALLA I/ALLA RIVER (KENDALL AND OTHERS, 1981)-"

.3

Items 4-10,definitely require expansion.

For example.,

items 4 and 5 are rejections of earlier models, and'etails supporting such conclusions should be provided.

These new conclusions allow removal of limbs from the. fault tree in Apendix 2.5 K.

The structural and tectonic model(s) presented

should, include enough detail to permit full, accurate evaluation of the'applicant's analysis of seismic probability, segmentation of.faults, and capability of

\\

faults.

Some of the support material expected is:

5 361.20 To-scale cross'section(s) of the geology through the site to a depth (USGS 1) sufficient to include the elements critical to evaluation of the'odel..

361.21 To-scale illustration of the geometry and ori gin of the folds and faults (USGS 2) common to. the.tectonic end-members of the "structural spectrum" referred to in Items 6 and 7 of "Conclusions":

(a) primary folding, secondary faulting, and (b) primary faulting, secondary folding.,

361.22 Maps and cross sections of actual examples within the "structural (USGS 3) spectrum;"

and explanation of how these examples bear on structural interpretations extended into the WBP-2 site area;

.-361.23 Well-illustrated explanations of the structural relationship between the (USGS 4)

RAW trend and the large folds (Gable Mountain, Saddle Mountains, and Frenchmen 'Hills) that extend far to the north and east of RAW; This explanation should include but not be limited to, adequate analysis of Price's (1981) model, Item 10 (2) of Conclusions,"

which suggests many I

miles of northward translation of an originally east-west-trending foldo How does this translation take place?

What is the evidence for translation and what bearing does the translation represented by this and other folds ha've on structural interpretations below the WNP-2 site?

~

361.24 (USGS 5)

Illustrate explanation of the applicant's concept of "* ~

• intracrustal thrust-type detachments and less-throughgoing zones of interconnected

'aults and kink-bands."

How do these relate to the "structural spectrum"?

Where are they or where would they be expected? 'how in

~ schematic cross section(s) the conceptual and spatial relationships between the hypothetical faults and the crustal levels of Appendix 2.5 K

(WPPSS, 1981),

and the examples within the "structural spectrum" (3,

above.

Show the'ertical zone through which the present-day north-south compression is acting.

Show depths of significant earthquakes projected

'nto cross section.

361.25 (USGS 6)

Provide.comparison, with suitable cross sections, of the 'structural geology of the Umtanum-Gable Mountain-southeast anticline with Toppenis'h Ridge.

Explain more fully what leads.you to postulate a fault origin for Toppenish (WCC. 1981a) and a fold origin for Umtanum-Gable Ridge (Item 7, "Concl usi ons").

Active Volcanism The'pplicant should assess the possibility of having a fissure 'lava flow at the site.
