Serpentinite foliated or nonfoliated
Quartzite is a nonfoliated metamorphic rock that consists mostly of quartz. It's usually a white to pale gray rock, but occurs in other colors, including red and pink (from iron oxide), yellow, blue, green, and orange. The rock has a grainy surface with a sandpaper texture, but polishes to a glassy shine.Serpentinite is a metamorphic rock that is mostly composed of serpentine group minerals. 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 ).

Examples of nonfoliated rocks include anthracite coal, hornfels, serpentinite, soapstone, quartzite, marble, and metaconglomerate. Wiki User Is garnet schist foliated or Nonfoliated? The rocks that are common are gneiss, schist and slate. Marble is non-foliated. Hornfels is a rock with no leaves. There are distinct minerals in the metamorphic minerals. What is mica schist quizlet? Schist describes the texture of rocks and is used to name rocks with many chemical compositions.
Serpentine is a metamorphic rock named for its resemblance to a snake's skin. It is typically green or greenish-black with flecks of lighter and darker color throughout the non-foliated rock. Answer and Explanation: 1Tightly folded serpentinite from the Tux Alps, Austria. Closeup view about 30 cm × 20 cm (11.8 in × 7.9 in). Serpentinite is a rock composed predominantly of one or more serpentine group minerals, the name originating from the similarity of the texture of the rock to that of the skin of a snake.Quartzite is a non-foliated, granoblastic (intergrown, interlocking, equidimensional, enlarged grains), metamorphic rock composed predominantly of quartz. It forms by the regional, burial or contact metamorphism of quartz-rich sandstones or chert. Grade: low to high; Parent Rock: quarrz-rich sandstone or chertSerpentinite is a metamorphic rock composed of one or more of the serpentine group minerals (antigorite, lizardite, and chrysotile).

Gneiss, a foliated metamorphic rock. Quartzite, a non-foliated metamorphic rock.. Foliation in geology refers to repetitive layering in metamorphic rocks. Each layer can be as thin as a sheet of paper, or over a meter in thickness. The word comes from the Latin folium, meaning "leaf", and refers to the sheet-like planar structure. It is caused by shearing forces (pressures pushing …May 29, 2018 · Migmatite. A migmatite, or "mixed rock" in Greek, is a banded, heterogenous rock composed of intermingled metamorphic and igneous components. Veins, contorted layers, and irregular pods of silica-rich granite occur within the structure of foliated iron and magnesium-rich metamorphic rocks like gneiss , schist and amphibolite. ….

The various types of foliated metamorphic rocks, listed in order of the grade or intensity of metamorphism and the type of foliation are slate, phyllite, schist, and gneiss (Figure 7.8). As already noted, slate is formed from the low-grade metamorphism of shale, and has microscopic clay and mica crystals that have grown perpendicular to the stress.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. SERPENTINITE - NONFOLIATED - Grade: VARIABLE .

Serpentinite is a soft, compact, pale green to greenish-black rock consisting wholly or largely of serpentine minerals—antigorite, chrysotile, or lizardite (allomorphs of Mg 3 Si 2 O 5 (OH) 4 ). These minerals are usually produced by the hydrous alteration of olivine, orthopyroxene, and, to a lesser extent, clinopyroxene.
