Low to medium grade metamorphic rock. Foliated mica schist containing some chlorite and quartz grains. Original rock was likely a muddy sandstone/siltstone. Could have been collected between Lake Louise and Golden.

Low grade metamorphic limestone (marble) with small pyrite crystals and small quartz veins. Metamorphism has resulted in recrystallization of the calcite (turning into marble). The presence of pyrite has resulted in an iron oxide coating. Original limestone had a few thin muddy layers resulting in …
Low grade metamorphic limestone (marble) with small pyrite crystals and small quartz veins. Metamorphism has resulted in recrystallization of the calcite (turning into marble). The presence of pyrite has resulted in an iron oxide coating. Original limestone had a few thin muddy layers resulting in minor occurrences of clay minerals.
Metamorphic rock. Garnet mica shchist. Two different types of mica - muscovite is evenly dispersed throughout the rock and biotite occurs in little pockets. Quartz is also evenly dispersed throughout the rock. Original rock, before metamorphism, would have been sandstone with little shale partings …
