Big hunk of greenstone matrix with fracture covered by parallel clinozoisite crystals and minor cross-cutting quartz and chlorite. Fred Davis tested this specimen using X-ray diffraction to confirm the species.
White tabular albite crystals in brown goethite.

Brown clinozoisite crystals with green chlorite on massive quartz.
Closeup where the goethite best shows some structure that looks like calcite cleavage angles suggesting that goethite may have replaced that mineral in the void spaces. Tabular white albite crystals are below and milky quartz around the upper and right edges.
Massive pyrite in quartz with minor green chlorite and brown clinozoisite.
Quartz crystals in a pocket lined with brown goethite that likely replaced calcite.
Fine-grained green chlorite crystals with brown clinozoisite.
Closeup of goethite with pale gray quartz crystals and white albite crystals. The goethite appears to have some structure at upper left that looks like calcite cleavage angles and may have replaced that mineral.
