Comments on the geologic information

  • OLDEST NAP UNIT IS A SILTY MONTMORILLONITE COLORED FROM VARIOUS SHADES OF GRAY, YELLOWISH-GRAY, TO BROWNISH GRAY. THE OVERLYING UNIT IS A GRAYISH-ORANGE, ALTERED MATERIAL THAT IS MAINLY GYPSUM, CRISTOBALITE AND OPAL. ALTHOUGH THE ORIGINAL ROCK TYPE IS NOT EVIDENT, IT PROBABLY WAS A TUFFACEOUS ROCK. IMPURITIES IN THE MONTMORILLONITE DEPOSIT INCLUDE CRISTOBALITE, PLAGIOCLASE, QUARTZ, K-FELDSPAR, CALCITE AND GYPSUM. A SERIES OF FAULTS WITH DIVERSE STRIKES AND LOW- TO HIGH-ANGLE DIPS USUALLY FORM THE CONTACT BETWEEN THE MONTMORILLONITE AND THE SILTSTONE. MOST OF THE FAULTS HAVE APPARENT MOVEMENTS OF LESS THAN 3 OF 4 FEET; A FEW HAVE DISPLACED 15 FEET OR MORE.
