Serpentinite (Fig. 7.12) is a metamorphic rock mos

Non-foliated metamorphic rocks are typically composed of just one mineral, and therefore, usually show the effects of metamorphism with recrystallization in which crystals grow together, but with no preferred direction. The two most common examples of non-foliated rocks are quartzite and marble. Quartzite is a metamorphic rock from the ... Foliated metamorphic rocks such as gneiss, phyllite, schist and slate have a layered or banded appearance that is produced by exposure to heat and directed pressure. Non-foliated metamorphic rocks such as hornfels, marble, quartzite and novaculite do not have a layered or banded appearance.High-grade metamorphic rocks, which form at temperatures greater than about 600 °C, are usually quite coarse-grained and contain minerals easily identified in hand specimen. Most form at high pressures. The high-grade rock shown in Figure 8.10 contains conspicuous centimeter-sized red garnet, black hornblende, and white plagioclase feldspar.Question: Quartzite Answer: Texture: Non-Foliated, Medium-Coarse Grained Composition: Siliceous Minerals: Mostly quartz.

Serpentine group minerals antigorite, lizardite, and chrysotile are produced by the hydrous alteration of ultramafic rocks. These are igneous rocks that are composed of olivine and pyroxene ( peridotite, pyroxenite ).A metamorphic rock composed principally of serpentine is thus a serpentinite. Serpentinite has a mottled greenish color, has the look & feel of hard candle wax, and ranges in texture from crystalline to "foliated". Many serpentinites have a foliated look to them, but it's really not due to an alignment of crystals. It may be schistose or massive. Soapstone is formed by metamorphism of ultramafic protoliths (eg dunite or serpentinite) and metasomatism of siliceous dolomites. By mass, “pure” steatite is roughly 63.37% silica, 31.88% magnesia, and 4.74% water. It commonly contains minor quantities of other oxides such as CaO or Al2O3.

Metamorphic rock identification table. Non-foliated rock does not have planar patterns of stress. Rocks that were subjected to uniform pressure from all sides, or those which lack minerals with distinctive growth habits, will not be foliated. Slate is an example of a very fine-grained, foliated metamorphic rock, while phyllite is coarse, schist coarser, and gneiss very coarse ...Dolomitic Marble is a coarse-grained, non-foliated metamorphic rock composed primarily of dolomite. It is usually white or off-white, but if impurities are present it may also contain colors like pink, gray, blue, or green. Dolomitic Marble is formed from the low-grade metamorphism of dolomite. Serpentinite often contains many veins, some of which may be filled with the fibrous mineral chrysotile (a form of asbestos). Chrysotile is a serpentine mineral in which the silica sheets are rolled into tiny tubes to form hollow fibers. Loose asbestos fibers cause lung disease if you inhale them.Non-foliated rocks of this mineralogy should be referred to calc-silicate rock , or preferably by a more specific name e.g. tremolite-diopside rock. Quartzite - foliated or non-foliated granoblastic metamorphic rock composed of > 90% quartz. Foliation if present can be defined by either elongation of quartz grains and/or aligned, sparse micas. Foliated: medium to coarse grained; banding- minerals segregated into alternating layers gives the rock a banded texture in side view; crystalline structure; visible crystals of two it more minerals in alternating light and dark foliated layers; parent rocks- mudstone, shale, slate, phyllite, schist, granite or diorite Non-foliated metamorphic rocks do not have aligned mineral crystals. Non-foliated rocks form when pressure is uniform, or near the surface where pressure is very low. They can also form when the parent rock consists of blocky minerals such as quartz and calcite, in which individual crystals do not align because they aren’t longer in any one ... Foliated serpentinite is directly formed from peridotite similar to the preferred orientation of mica in many metamorphic rocks. It suggests that crystal plastic deformation by dislocation glide may not be the dominant mechanism for antigorite CPO in the initial stage of antigorite serpentinization.Examples of foliated rocks include: gneiss, phyllite, schist, and slate.
