Click the show button to view. A schistose metamorphic rock with chlorite minerals as the major (>50%) constituent. Chlorite imparts a schistosity by parallel arrangement of its flakes. Quartz, epidote, magnetite, and garnet may be accessories, the last two often as conspicuous porphyroblasts.
contact us· Phyllite is between slate and schist in the spectrum of metamorphic rocks.Geologists tell them apart by their surfaces: slate has flat cleavage faces and dull colors, phyllite has flat or crinkled cleavage faces and shiny colors, and schist has intricately wavy cleavage (schistosity) and glittering colors. Phyllite is "leaf-stone" in scientific Latin; the name may refer as much to phyllite''s ...

contact uschlorite schist The word schist is derived from the Greek word schízein meaning "to split", which is a reference to the ease with which schists can be split along the plane in which the platy minerals lie. Schist is a medium-grained strongly-foliated crystalline metamorphic rock, formed by dynamic metamorphism, that can be readily split into ...

Chlorite schist is the weakest sample, having a residual coefficient of friction μ of 0.36.
contact usA greenstone-schist is composed of chlorite, with some feldspar, quartz and calcite. This should be compared with an analysis of gabbro which represents the gabbro-dolerite group. The greenstones vary in color from pale gray green through yellow-green to dark green. The color depends on the proportion of chlorite to other minerals.

contact us· 2.2 Mineral composition of chlorite schist. Chlorite minerals concentrate along the dominant development direction, and agglomerate into a heterogeneous layer, forming interbedding with quartz, mica, and albite minerals. This special distribution of minerals forms the macro schistose structure of chlorite schist.
