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 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 …

Low grade metamorphic rock. Recrystallized vuggy limestone (marble). Well developed calcite rhombs in the vugs (cavities). “23” written in red on black on underside.

Metamorphic rock. Quartzite, probably from the Gog formation. It has alternating bands of white and rose quartz grains. It has been subjected to very low grades of metamorphism. The number “73” is painted on the underside in red on black.

Low grade metamorphic rock. Marble with several quartz veins running through it. Pyrite associated with the quartz has weathered resulting in a coating of iron oxide on the marble/limestone surface. Weathering of the pyrite has also resulted in the etching of the quartz.
