The difference between serpentinite and chlorite schist is that.

Greenschists are metamorphic rocks that formed under the lowest temperatures and pressures usually produced by regional metamorphism, typically 300–450 °C (570–840 °F) and 2–10 kilobars (29,000–145,000 psi). Greenschists commonly have an abundance of green minerals such as chlorite, serpentine, and epidote, and platy minerals such as muscovite and platy serpentine. The pl…Talc ± actinolite schist is in contact with a serpentinite block and chlorite-actinolite schist is in contact with ... 4.1 Chlorite-Actinolite Schist.

These are invariably green, black and, more rarely, blue in color. This general name encompasses rocks that are also referred to as greenschist ,Included are specimens of Gneiss, Graphite schist, Mica schist, Garnet schist, Chlorite schist, Slate, Phyllite, Soapstone, Quartzite, Serpentinite, Epidosite, ...(d) Transition from serpentinite at the bottom to chlorite schist (Zone IV), omphacite–chlorite rock (Zone III) and glaucophane–epidote–chlorite rock (Zone II).

The REE pattern of the chlorite schist rimming the Punta Rossa serpentinite is identical to REE patterns of chlorite schists from New Caledonia (Spandler et al., 2008). It is not possible to determine if the metasomatism is a relict seafloor feature or formed during subduction or exhumation of the margin.

Phyllite. foliated metamorphic rock that is made up mainly of very fine-grained mica. The surface of phyllite is typically lustrous and sometimes wrinkled. It is intermediate in grade between slate and schist. Quartzite. non-foliated metamorphic rock that is produced by the metamorphism of sandstone. It is composed primarily of quartz.Most of the soils in the RCT are shallow to moderately deep (25–100 cm depth). A typical horizon sequence in both peridotite and serpentinite soils is Oi-A-Bt-C-R. The most obvious difference between the peridotite and serpentinite soils is that the peridotite soils are redder ( Alexander, 2004, Alexander, 2009 ).(a) antigorite serpentinite with minor talc, magnetite, and chromite grains in Zone I, (b) euhedral, prismatic amphibole schist with chlorite and ilmenite in Zone II, (c) BSE image of ilmenite ...Chlorite Schist: Composed mainly of chlorite minerals, giving it a green color and often a platy texture. Talc Schist : Dominated by talc minerals, known for its softness and soapy feel. Graphite Schist : Contains significant amounts of graphite, resulting in a dark color and sometimes a metallic luster.In phyllite, the flakes have grown larger as evidenced by an increase in luster. In schist, the platy minerals are clearly visable to the naked eye. 3. Schist is often named for their most abundant minerals. Thus there are quartz-mica schist, garnet-mica schist (Fig. 8.10), muscovite schist and actinolite schist. 4.

In the chlorite schist end-member, a localized, <100 μm thick, slip zone marks a boundary between chaotic and foliated chlorite above and a lack of foliation below (Figures 10c and 10d). Along the slip surface, well-oriented, slip surface-parallel chlorite grains are locally present (Figure 10d ).
