Which Type Of Rock Is Quartzite Schist Marble

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 type of rock is quartzite schist marble.

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. What is the usual orientation of foliation. Schist and gneiss are two different types of rocks that look remarkably like. Gneiss on the other hand is formed in the pattern of layers of sheet like planar structures.

Vertical and perpendicular to stress. The following is a list of rock types recognized by geologists. Quartzite is a nonfoliated metamorphic rock composed almost entirely of quartz. These conditions recrystallize the sand grains and the silica cement that binds them together.

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. Which of these metamorphic rocks is not foliated. Which rock type represents the lowest grade of. Additionally different classification systems exist for each major type of rock.

The original parent rock or protolith of mica schist is shale. There is no agreed number of specific types of rocks. Any unique combination of chemical composition mineralogy grain size texture or other distinguishing characteristics can describe a rock type. The hardness of marble is 3 4 and that of schist is 3 5 4.

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. Which rock type represents the highest grade of metamorphism from a shale. In this hand specimen of vermont marble the crystals are small. Gneiss phyllite quartzite schist slate.

Rock density is very sensitive to the minerals that compose a particular rock type. Sedimentary rocks and granite which are rich in quartz and feldspar tend to be less dense than volcanic rocks. Schist is a strongly foliated medium grade metamorphic rock. It forms when a quartz rich sandstone is altered by the heat pressure and chemical activity of metamorphism.

Marble is made by regional metamorphism of limestone or dolomite rock causing their microscopic grains to combine into larger crystals. This type of metamorphic rock consists of recrystallized calcite in limestone or dolomite in dolomite rock. Phyllite could also be considered the parent rock as mica schist is a more highly metamorphosed phyllite. The hardness of quartzite is 6 7 and that of schist is 3 5 4.
