Metamorphic texture is the description of the shape and orientation of mineral grains in a metamorphic rock. Metamorphic rock textures are foliated, non-foliated, or lineated are described below. Metamorphic rock identification table.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 a traverse across a Syros mafic eclogite block with a narrow chlorite schist reaction zone and broader glaucophane-rich reaction zone, the Os, Ir, Ru, and Cr concentrations in the chlorite schist are just barely higher than those in the eclogite block, while the initial 187 Os/ 188 Os ratio falls between the eclogite core and adjacent ...In the field, serpentinite and talc-tremolite schist occur as small lensoidal bodies and enclaves within granite gneiss.

Figure 13.1 shows some common minerals found in metabasites (metamorphosed mafic rocks) at different metamorphic grades. A spectrum of minerals is possible, beginning with zeolites, prehnite, and pumpellyite, at low grade. And, ending with hornblende, garnet, biotite, diopside, or …Schist. Schist is a strongly foliated medium-grade metamorphic rock. It is characterized by an abundance of platy or elongated minerals (micas, chlorite, talc, graphite, amphiboles) in a preferred orientation. Varieties of this rock type share similarities in appearance (schistosity) but may be highly variable in composition.Talc schist deposits are reported in central Cameroon region, and different alteration zones were determined depending on differences related to the texture and color of the host rock.

Here, the chlorite structure is depicted as consisting of a brucite-like layer (with some Al) sandwiched between tetrahedral layers that are similar to phlogopite. Another important sheet silicate structure is that of vermiculite. This is similar to the talc structure, discussed above, with layers of water molecules occurring between each T-O-Tstringer zones. The contact between serpentinite and the chlorite-epidote schist unit is complex. Most of the contact is altered, sheared, and filled with mafic dikes, and the contact seems to transect structure in the layered rocks. In outcrop, the serpentinized rocks are various shades of brown, yellow, green, and gray, the result of ...
Talc schist forms a 2–4 m thick layer between ultramafic and mafic 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.
