Economic information

Comments on the geologic information

  • BORATES OCCUR WITHIN GREEN-GREY SHALES INTERBEDDED WITH YELLOW-TAN LIMESTONES. THERMAL SPRING ACTIVITY ASSOCIATED WITH NUMEROUS FAULTS IN THE AREA PROVIDED SOURCE OF BORON. BORATES DEPOSITED CYCLIC SEQUENCE IN SHALLOW-DEEP LACUSTRINE ENVIRONMENTS (PLAYA) COVERED POSSIBLY AN AREA OF 15 KM X 100-150 KM. THE BARSTOW-BRISTOL VOLCANIC-TECTONIC TROUGH PROBABLY DEVELOPED AS A BROAD SYNCLINAL DOWNWARP. POST DEPOSITIONAL FAULTING UPLIFTED AND FOLDED B-BEARING SEQUENCE INTO 'TIGHT FOLDS'. B-BEARING BEDS GENERALLY OCCUR IN THE NE LIMB OF THE BARSTOW SYNCLINE. VOLCANIC AGGLOMERATE OVERLY THE BARSTOW FM.
