Understanding the differences between these two rocks can help geologists identify and classify … Read moreSchist and gneiss can be named on the basis of important minerals that are present: a schist derived from basalt is typically rich in the mineral chlorite, so we call it chlorite schist. One derived from shale may be a muscovite-biotite schist, or just a mica schist, or if there are garnets present it might be mica-garnet schist.

Mafic Schist - foliated or nonfoliated rock of any grain size composed predominately of mafic minerals (particularly chlorite, epidote, amphibole, pyroxene) and plagioclase. These are invariably green, black and, more rarely, blue in color. This general name encompasses rocks that are also referred to as greenschist ,(d) Transition from serpentinite at the bottom to chlorite schist (Zone IV), omphacite–chlorite rock (Zone III) and glaucophane–epidote–chlorite rock (Zone II). (Note hammer for scale.)Serpentinite is a rock composed predominantly of one or more serpentine group minerals, the name originating from the similarity of the texture of the rock to that of the skin of a snake. [1] Serpentinite has been called serpentine or serpentine rock, particularly in older geological texts and in wider cultural settings. [2] [3] [4] [5] [6]Schist is a type of metamorphic rock in which lamellar minerals, such as muscovite, biotite, and chlorite, or prismatic minerals, such as hornblende and tremolite, are oriented parallel to a secondary platy or laminated structure termed the schistosity. The mineral grains in many examples are large enough to be recognized in hand specimens. The schist is type of medium-grade metamorphic rock that contains flat, sheet like grains in a pattern. Gneiss, on the other hand, is formed in the pattern of layers of sheet-like planar structures. Schist and Gneiss are two different types of rocks that look remarkably like. The reason for this is because they are both types of metamorphic rock. Serpentinite vs. Chlorite Schist: Texture. The texture of serpentinite and chlorite schist also varies significantly. Serpentinite is a dull, waxy, greasy rock with a fine-grained texture. Its surface often has a slippery, soapy …stringer zones. The contact between serpentinite and the chlorite-epidote schist unit is complex.
