Serpentinite foliated or nonfoliated

To identify metamorphic rocks, you will first need to determine if the rock is foliated or non-foliated. Examine the rock for evidence of any pattern or foliation, and if present, identify the size and mineral(s) that compose the foliation pattern ( Figure 13.8, left ). .

Serpentinite in turn is highly reactive with CO 2 and sequesters carbon for millions of years via the formation of magnesite. During carbon uptake, mineral bound …Foliation Non-foliated. Picture Serpentine marble, Rock Number 45, Rock Name Serpentine marble, Metamorphic Grade Low to high grade, Foliation Non-foliated.

Foliated rocks have platy or elongate minerals aligned in roughly parallel planes or in wavy bands or planes. Nonfoliated rocks may show colored bands that ...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.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.

Phyllite with a small fold. (Source: Peter Davis) Phyllite is a foliated metamorphic rock in which platy minerals have grown larger and the surface of the foliation shows a sheen from light reflecting from the grains, perhaps even a wavy appearance, called crenulations.Similar to phyllite but with even larger grains is the foliated metamorphic rock schist, which has …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: 1
