Geologic structures

Type of structure Regional
Structure description The Kobau Formation Was Deposited Along An Active Continental Margin Proximal To An Island Arc.

Controls for ore emplacement

  • The Deposit Is On The Same Fault And Is Similar To The Ruby Deposit. The Vein Trends N65w, Dips 35sw, And Can Be Traced For 3000 Feet Along The Outcrop. The Vein Is Altered As Much As 4 Feet From The Fault (Huntting, 1956, P. 307; Rinehart And Fox, 1972, P. 96).

Comments on the geologic information

  • THE KOBAU FORMATION IS INTRUDED BY GRANODIORITE AND TONALITE OF THE TRIASSIC-JURASSIC LOOMIS PLUTON. MINERALIZATION IS PRESENT IN A WEST-NORTHWEST TRENDING-FAULT NEAR THE CONTACT (RINEHART AND FOX, 1972, GEOL. MAP).
