Title

Muscovite schist

Identifier

DUCO-12

Description

Extremely coarse-grained muscovite schist. Large garnets visible in hand sample. Sillimanite is not recognizable in hand sample, however.

The thin section shows muscovite (with minor sillimanite) in a large band, biotite, staurolite, and quartz.

This rock is from the sillimanite zone of the Barrovian metamorphic sequence (highest metamorphism).
