|---|---|
| Deposit | ORE MINERALS FORM MASSES AND SMALL GRAINS THROUGHOUT HORNBLENDE-ACTINOLITE-TREMOLITE SCHIST ENCLOSED IN QUARTZITIC GNEISS. MINERALIZATION APPARENTLY LATER THAN CRYSTALLIZATION OF AMPHIBOLES. DEPOSIT IS SIMILAR TO OTHER FRONT RANGE HYPOTHERMAL REPLACEMENTS OCCURRING IN ACTINOLITE SCHIST OR OTHER CA-RICH ROCKS NEAR EDGE OF LARGE GRANITIC MASS. |
| Deposit | MINE IS INCLUDED IN MALACHITE DISTRICT BECAUSE OF SIMILARITY OF ROCK TYPES AND TYPE OF MINERALIZATION. ; INFO.SRC : 1 PUB LIT |
