WebbFinal study guide Igneous. Igneous textures: glassy-no crystals, aphanitic- <1 mm, phaneritic- 1-10mm, pegmatitic- > 10 mm Felsic rocks- rich in silica, al, K, Na mafic rocks- rich in Fe, Ca, Mg, low in silica Solid solution series- continuous change in chemistry between two end members (e., plag- albite to anorthite; olivine- forsterite to fayalite) … WebbAs explained above, mica minerals such as chlorite, muscovite, and biotite are the characteristic minerals of schist. These were formed through metamorphism of the clay minerals present in the protolith. Other common minerals in schist include quartz and feldspars that are inherited from the protolith.

WebbThe rock is called protomylonite if the porphyroclasts make up more than half of the rock volume and ultramylonite if almost all the porphyroclasts are gone (less than 10% have survived). In the latter case the matrix grains are so … WebbAnswer choices. K is the mylonite. It has chunks of garnet in it. K is the mylonite. It has angular clasts and slickensides on the lower surface of the sample. L is the mylonite. It has chunks of garnet in it. L is the mylonite. It displays "augen" of several minerals, with "tails" that stretch out parallel to the foliation.

The different metamorphic facies are defined by the mineralogical composition of a rock. When the temperature or pressure in a rock body change, the rock can cross into a different facies and some minerals become stable while others become unstable or metastable.Whether minerals really react depends on the reaction kinetics, … rcpch 0-4 yearsWebbThe protolith of slate is shale.

The change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. sims drive branch office
