Serpentinite foliated or nonfoliated.

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.

Figure 10.39, however, is a hand specimen of a garnet amphibolite, reminding us that amphibolites need not be nondescript and that they may be foliated. Amphibolites form by metamorphism and recrystallization of basalt or other mafic igneous rocks.

Foliated rocks are formed under a great amount of relatively equal pressure, where as non-foliated rocks are formed under high temperatures. Non-foliated rocks, however, lack this visual characteristic. See the image below. The reason for this is actually pretty intuitive. Foliated metamorphic rocks look like they've been "smashed" together for a reason: they …Foliated (Banded) Metamorphic Rocks. In this texture, the mineral crystals in the rock are aligned with each other. This alignment may be displayed as parallel planes along which the rock splits, by overlapping sheets of platy minerals such as micas, by the parallel alignment of elongate minerals such as amphiboles, or by alternating layers of light and dark minerals.

Group of answer choices ...Amphibolite can be either foliated or nonfoliated. Examples of nonfoliated rocks include anthracite coal, hornfels, serpentinite, soapstone, quartzite, marble, and metaconglomerate.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.on the basis of texture (foliated vs. non-foliated), grain-size, and mineral composition. Texture: Metamorphic rocks may have either foliated (layered) or non-foliated texture. Foliated texture is a pervasive layering caused by compositional layering or by the parallel orientation of platy (e.g, mica) or elongate (e.g., amphibole) mineral grains.

Examples of foliated rocks include: gneiss, phyllite, schist, and slate. Non-foliated metamorphic rocks do not have a layered or banded appearance.

During carbon uptake, mineral bound …Amphibolite is a non foliated metamorphic rock that is mainly composed of mineral amphibole and plagioclase feldspar with little or no quartz. The amphibole are usually the member of the hornblende group. It can also contains other metamorphic minerals such as biotite, epidote, garnet, wollastonite, andalusite, staurolite, kyanite and …

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.Question: Quartzite Answer: Texture: Non-Foliated, Medium-Coarse Grained Composition: Siliceous Minerals: Mostly quartz.

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.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.
