Lithology Comments

Sep 10, 2015 (A Wilson) - Mica and apatite occur in calcite veins cutting dark pyroxenite. The veins strike east-west and average 2.5 feet wide at the surface. The mica-apatite leads trend northeast and southwest with a dip to the northwest. The minerals occur in pockets and fissure in pyoxenite. Some leads carry pink calcite. The mica usually occurs on the hanging-wall contact of pyroxenite with country rock.
