Which Type Of Rock Is Quartzite Schist Marble

Gneiss phyllite quartzite schist slate.

Which type of rock is quartzite schist marble.

And if you know your igneous petrology you will see that the more mafic rich in magnesium and iron a rock is the greater its density. The original parent rock or protolith of mica schist is shale. The schist is type of medium grade metamorphic rock that contains flat sheet like grains in a pattern. The types of quartzite are not available whereas types of schist are mica schists calc silicate schists graphite schists blueschists whiteschists greenschists hornblende schist talc schist chlorite schist garnet schist glaucophane schist.

Sedimentary rocks and granite which are rich in quartz and feldspar tend to be less dense than volcanic rocks. Rock density is very sensitive to the minerals that compose a particular rock type. The types of marble are breccia marble carrara marble calacatta marble cultured marble polished marble honed marble sand marble whereas types of schist are mica schists calc silicate schists graphite schists blueschists whiteschists greenschists hornblende schist talc. Which rock type represents the highest grade of metamorphism from a shale.

It forms when a quartz rich sandstone is altered by the heat pressure and chemical activity of metamorphism. In this hand specimen of vermont marble the crystals are small. Mica schist the most common schistose rock and the second most common metamorphic rock is composed mostly of mica usually biotite or muscovite and smaller amounts of quartz. It is characterized by an abundance of platy or elongated minerals micas chlorite talc graphite amphiboles in a preferred orientation varieties of this rock type share similarities in appearance schistosity but may be highly variable in composition.

This type of metamorphic rock consists of recrystallized calcite in limestone or dolomite in dolomite rock. Additionally different classification systems exist for each major type of rock. Streak of rock is the color of. What is the usual orientation of foliation.

These conditions recrystallize the sand grains and the silica cement that binds them together. Schist is a strongly foliated medium grade metamorphic rock. The hardness of quartzite is 6 7 and that of schist is 3 5 4. Any unique combination of chemical composition mineralogy grain size texture or other distinguishing characteristics can describe a rock type.

Vertical and perpendicular to stress. Phyllite could also be considered the parent rock as mica schist is a more highly metamorphosed phyllite. There is no agreed number of specific types of rocks. Which of these metamorphic rocks is not foliated.

Quartzite is a nonfoliated metamorphic rock composed almost entirely of quartz. The following is a list of rock types recognized by geologists. Schist and gneiss are two different types of rocks that look remarkably like. Which rock type represents the lowest grade of.
