General comments

Subject category Comment text
Deposit SCHEELITE AND MOLYBDENITE ARE DISSEMINATED IN A TACTITE ZONE FLANKING AN APLITE DIKE. APLITE DIKE IS VERTICAL AND CUTS A SILL OF THE GRANITIC NOTCH PEAK INTRUSION AND SURROUNDING LIMESTONE. TACTITE ZONE DOES NOT EXTEND MORE THATN 18 CM FROM THE APLITE DIKE. SOME MOLYBDENITE OCCURS IN QUARTZ VEINLETS ALONG THE EDGES OF THE DIKE. SOME MOLYBDENITE, SCHEELITE, PYRITE, AND MINOR CHALCOPYRITE ARE DISSEMINATED IN TEH APLITE DIKE. MINERAL ASSEMBLAGE IS TYPICAL OF TUNGSTEN SKARN DEPOSITS: W + MO + ZN + CU.
