The difference between serpentinite and chlorite schist is that
Jul 1, 2022 · The chlorite schist is fine- to medium-blastic and its color varies from gray to black. Contacts of the chlorite schist with both the talcose rock and serpentinite are commonly sharp (Fig. 3), and only locally the gradual contact of the chlorite schist with the talcose rock can be seen, especially under the microscope. The major phase is ... Included are specimens of Gneiss, Graphite schist, Mica schist, Garnet schist, Chlorite schist, Slate, Phyllite, Soapstone, Quartzite, Serpentinite, Epidosite, ...

The hydrothermal metamorphism results in alteration to such Mg-Fe rich hydrous minerals as talc, chlorite, serpentine, actinolite, tremolite, zeolites, and clay minerals. Rich ore deposits are often formed as a result of hydrothermal metamorphism. Burial Metamorphism. biotite schist, biotite schist, and marble. Relict bedding in the schist unit has gentle to moderate dips. The serpentinite is highly sheared and altered to asbestiform tremolite, talc, magnesite, calcite, and iron oxides. It is generally conformable with the hornblende schist and overlies it, probably in thrust contact.Chlorite in a Garnet-Paragonite Schist .

Deposits of two formation types were established here: apoultrabasic (East Sayan and Dzhida areas, Parama massif) and apocarbonate (Vitim area). Nephrites compose schlieren and lenticular bodies usually in the zones of …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. ….

We estimate the cumulative thickness of talc to be ∼10 m, given its distribution relative to the associated lithologies and our field observations.(d) Transition from serpentinite at the bottom to chlorite schist (Zone IV), omphacite–chlorite rock (Zone III) and glaucophane–epidote–chlorite rock (Zone II).
