Schist and Their Composition

Mica minerals such as chlorite, muscovite, and biotite are the characteristic minerals of schist. These were formed through metamorphism of the clay minerals present in the protolith.

Other common minerals in schist include quartz and feldspars that are inherited from the protolith. Micas, feldspars, and quartz usually account for most of the minerals present in a schist.

Schists are often named according to the eye-visible minerals of metamorphic origin that are obvious and abundant when the rock is examined. Muscovite schist, biotite schist, and chlorite schist (often called “greenstone" are commonly used names.

Other names based upon obvious metamorphic minerals are garnet schist, kyanite schist, staurolite schist, graphite schist. Some names used for schist often consist of three words, such as garnet graphite schist.

In these cases the dominant metamorphic mineral’s name is used second, and the less abundant mineral name is used first. Garnet graphite schist is a schist that contains graphite as its dominant mineral, but abundant garnet is visible and present.

Major mica mica is present as a composite mineral...The Rock is foliated which means it separates easily....

These core drill results 63.3 mm wide split during recovery...like pages in a book while it is medium hard rock it is foliated....The slide below shows splits at 60% demonstrating the layers and strength of binding material...
