What are the minerals in schist?

Answer 1

The schists constitute a group of medium-grade metamorphic rocks, chiefly notable for the preponderance of lamellar minerals such as micas, chlorite, talc, hornblende, graphite, and others. Quartz often occurs in drawn-out grains to such an extent that a particular form called quartz schist is produced. By definition, schist contains more than 50% platy and elongated minerals, often finely interleaved with quartz and feldspar.

Answer 2

Schists are usually classified on the basis of their mineralogy, with varietal names that indicate the characteristic mineral present. Talc schist contains abundant talc; it has a greasy feel, a well-developed schistosity, and a grayish-green colour. Mica schist often contains muscovite mica rather than biotite, although both minerals are common. It represents a somewhat higher grade of metamorphism than talc schist and is more coarse-grained; individual flakes of mica can be seen

Answer 3

Common minerals associated with schist are chlorite, mica, garnet, and talc.

Answer 4

Yes, but not very often as it is not very structurally strong. It is the traditional building material on some Greek islands (like Andros) and in parts of Portugal.

Answer 5

Schistose foliation composed of intermixed quartz, feldspar, and biotite (with some possible amphibole).

Answer 6

Schist is a metamorphic rock.
