Deposit LARGE BODY OF METAGABBRO COVERS ABOUT 4 SQ MI; FOLIATION TRENDS VARIABLE NE-SW TO NORTH-SOUTH, MOSTLY VERTICAL DIPS. METAGABBRO CONTAINS SEVERAL TABULAR BODIES OF DIORITE-GABBRO ROCK OF DIFFERENT COMPOSITION AND TEXTURE THAN METAGABBRO. LOCALLY INTRUDING NW AND SE MARGINS OF METAGABBRO ARE TWO LINEAR BODIES OF GNEISSIC QUARTZ DIORITE 500 TO 1500 FT WIDE IN PLAN. BEYOND QUARTZ DIORITE, POWDERHORN GRANITE INTRUDES, WITH SEVERAL SMALL BODIES WITHIN METAGABBRO. ON WEST, FAULTS DISPLACE METAGABBRO AGAINST GRANITE. AREAS EAST AND SW OF METAGABBRO COVERED BY OLIGOCENE TUFFS. VEINS, QUARTZ VEINS, AND TRACHYTE DIKES INTRUDE METAGABRRO GENERALLY ALONG FOLIATION, BUT SOME CUT FOLIATION AT HIGH ANGLES. DIP OF VEINS MEASURED AT 44 TO 85 DEG. MOST VEINS HAVE BEEN PROSPECTED. ORIGIN OF MINERALIZATION UNCERTAIN BUT COULD BE (1) REMOBILIZATION OF SUBMARINE MASSIVE SULFIDES DEPOSITED IN GABBRO SEQUENCE, OR (2) LATE-STAGE HYDROTHERMAL VEIN DEPOSITS ASSOCIATED WITH EMPLACEMENT OF LATE PRECAMBRIAN TO
