Altered Basalt-greenstone

Pyroxenite
Coarse pyroxenite, with traces of nepheline. This is the freshest pyroxenite that was found. It occurs near the nepheline syenite body in the eastern part of the complex.

PH-2.
Fenitized Gneiss. Gneiss discovered in direct contact with pyroxenite in prospect trench on ridge, about 500 ft. west of PH-1.. .

PH-3.
Nepheline syenite that outcrops on west side of trail at about 9200 ft. on east side line of section.

PH-4.
Nepheline Syenite. Thin, dark vein runs through the center body of the rock.
