| Deposit | PLACER DEPOSITS WERE FOUND IN TERRACE DEPOSITS. THE LIMESTONES HAVE BEEN ALTERED IN VARIOUS DEGREES BY THE BOULDER BATHOLITH. MANY PLACES THE GARNET TACTITES WERE HOSTS FOR THE LODE DEPOSITS. SOME LODES WERE DEPOSITED IN VEINS THAT WERE ON ORE NEAR THE CONTACT OF THE LIMESTONE AND THE QUARTZ MONZONITE. |
