| Deposit | THE APEX MINE OCCURS IN ROCKS OF THE SNOQUALMIE BATHOLITH, NORTHERN PHASE, WHICH CONSISTS OF GRANODIORITE AND TONALITE AND IS LIGHT COLORED, MEDIUM CRYSTALLINE, AND MOSTLY EQUIGRANULAR AND HAS HYPIDIOMORPHIC TEXTURE. THE ROCKS ARE COARSELY JOINTED AND CONTAIN BIOTITE AND HORNBLENDE AND LOCALLY CLINOPYROXENE. AGE OF THE NORTHERN PHASE IS ABOUT 25 M.Y. BASED ON INTERPRETATION OF NUMEROUS DISCORDANT K-AR AGES OF BOTH HORNBLENDE AND BIOTITE (TABOR AND OTHERS, 1982, P. 8). ; INFO.SRC : 1 PUB LIT |
