How Is Metamorphic Rock Classified

How Is Metamorphic Rock Classified

Nonfoliated metamorphic rock usually contains one mineral. It is uniform in texture. Texture-Grain Size. Grain size is an important characteristic of texture. It ranges from very fine to coarse. The metamorphic rock classification chart below may help you make sense of the many different types of rock.

Differences Between Foliated  Non-Foliated Metamorphic Rocks

Differences Between Foliated Non-Foliated Metamorphic Rocks

Both foliated and nonfoliated rocks begin their lives as either sedimentary igneous or another metamorphic rock. Due to geological changes a metamorphic rock of the foliated or nonfoliated type will be created. These geological changes can be due to heat and temperature from the recrystallizing rock being found deep within the earth s crust.

Apr 25 2017 · Foliated rocks generally develop from parent rocks containing multiple minerals or from mixtures of multiple rock types. The nonfoliated metamorphic rocks marble and quartzite develop under conditions of differential stress when the original rocks are relatively pure and do not grow new mineral types to develop foliation.

Basics--Metamorphic Rocks Table

Basics--Metamorphic Rocks Table

Most metamorphic rocks form during regional metamorphism where whole sectors of the crust are pressurized and heated forcing large volumes of rock to recrystallize into new minerals that are stable under the new conditions. As a result rocks are changed into metamorphic rock across a region that may be many miles wide.

Quartzite Metamorphic RockPictures Definition More

Quartzite is a nonfoliated metamorphic rock composed almost entirely of quartz. It forms when a quartz-rich sandstone is altered by the heat pressure and chemical activity of metamorphism. These conditions recrystallize the sand grains and the silica cement that binds them together. The result is a network of interlocking quartz grains of
