Geology Comments

Dec 07, 2005 (C Salo) - The zone of talc-carbonate-serpentine altered ultramafic rock occurs approximately 50 m southwest of the margin of the Weslemkoon batholith as shown on Figure 35. It strikes northwesterly with a steep dip to the southwest. To the north of the zone is banded, quartz- biotite-hornblende schist, and to the south, amphibolitic metabasalt (LeBaron and van Haaften 1989). Cashel Township was mapped by Lumbers (1968). The talc unit is comprised of a series of talc-carbonate-anthophyllite altered ultramafic units,2 m to 10 m wide, separated by narrow bands of chlorite schist, biotite schist and quartz biotite schist which are 20 cm to 40 cm wide (LeBaron and van Haaften 1989).
