Summary:

Hanover Schist of Hatchet Creek Group is an interbedded sequence of coarse- to fine-grained (staurolite+/-)-albite-biotite-sericite-quartz-muscovite schist and (staurolite+/-)-biotite-feldspar gneiss, with garnet, chlorite, and sillimanite as common accessory minerals. Some units include graphitic feldspathic schist, hornblende quartzite, and thin amphibolite. Sericite commonly occurs as fibrous elliptical porphyroblastic aggregates. Locally, the schist is saturated with leucocratic granitoid rock.
