Deposit A WELL-DEVELOPED PATTERN OF MINERALOGIC ZONATION EXISTS IN THE DISTRICT. THE ZONASTION IS CONCENTRIC AROUND THE TAHONAS PORPHYRY COPPER DEPOSIT. PRELIMINARY INCLUSION STUDIES DOCUMENT HOMOGENIZATION TENPERATURES BETWEEN 217 DEGREES AND 434 DEGREES CENTIGRATE, AND SALINITIES OVER 20 EQUIV WT % NACL FOR QUARTZ FROM THE TAHONAS PORPHYRY COPPER DEPOSIT. STUDIES ON QUARTZ FROM OUTLAYINGREGIONS GIVE HOMOGENIZATION TEMPERATURE RANGES OF 24 DEGREES TO 351 DEGRSS C, AND SALINITIES OF FROM 9 TO 18 EQUIV WT % NACL STUDIES OF THE LATER GENERATION OF CALCITE, SILVER, AND MINOR SULFIDES GIVE TH VALUES BETWEEN 137 DEGREES AND 257 DEGREES C FOR CALCITE AND 170 DEGREES TO 196 DEGREES C FOR SALINITIES IN CALCITE ARE CONCENTRATED BETWEEN 7.6 AND 13.2 EQUIV WT % NACL.
Deposit THE TAHONAS PORPHYRY IS BELIVED BY WILKERSON, ET AL, 1988 TO BE THE CENTER (HEART) OF THE BATOPILAS DISTRICT, WITH CONCENTRIC ZONING AND MINERALIZATION AROUND INTRUSIVE. ; INFO.SRC : 1 PUB LIT
