Description

The graywacke facies in the Mt. Merino member (where sample 4 also comes from). Graywacke is a hard, dark-colored sandstone. This sandstone represents a similar rock to the protolith for the quartzite of sample 10.

The thin section shows quartz, feldspar, and lithics.

This rock is from the chlorite zone of the Barrovian metamorphic sequence (low metamorphism).

This rock was collected from the west end of a large road cut where samples 1 and 2 were also collected from.
