Deposit THIS RECORD CONTAINS DATA FROM RECORD K002895 BY HELMUTH WEDOW WHICH HAS BEEN DELETED FROM MRDS. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT
Deposit DEPOSITS IN THE CENTRAL DISTRICT ARE VEIN AND VEIN REPLACEMENT ZINC-LEAD-COPPER-SILVER ORE DEPOSITS. NUMEROUS FAULTS TRAVERSE THE REGION AND MINERALIZING FLUIDS FOLLOWED THE FAULTS. THERE WERE THREE PERIODS OF MINERALIZATION; MAJOR MINERALIZATION TAKING PLACE DURING THE SECOND PERIOD. ALL OF THE INTRUSIVE ROCKS HAVE BEEN HYDROTHERMALLY ALTERED. A CONCLUSION WAS DRAWN BY LASKY (1936, P.L) THAT EACH GENERAL PERIOD OF INTRUSION WAS FOLLOWED BY ROCK ALTERATION THAT PASSED AS A CONTINUOUS PROCESS INTO VEIN FORMATION.
Deposit VEIN PROBABLY RELATED TO ONE OR MORE GENERALLY NE-TRENDING FAULTS WITHIN EUREKA GRABEN SYSTEM THAT CUT EUREKA TUFF AND ITS ASSOCIATED MEGABRECCIA IN SAN JUAN-UNCOMPAHGRE CALDERA INFILL SEQUENCE.
