Non-Foliated Metamorphic Rocks

Non-foliated metamorphic rocks do no longer have a platy or sheet-like shape. There are numerous ways that non-foliated rocks may be produced. Some rocks, including limestone are product of minerals that aren’t flat or elongate.


Eclogite is a type of metamorphic rock with distinct mineral composition and texture, typically formed under high-pressure and high-temperature conditions deep within the Earth's...


Granulites are a type of high-grade metamorphic rock that forms under conditions of high temperature and pressure. They are characterized by the presence of...


Unakite is a type of metamorphic rock that is primarily composed of pink orthoclase feldspar, green epidote, and clear to bluish-gray quartz. It is...


Pinolith is a unique and visually striking metamorphic rock that is primarily composed of two distinct minerals: white magnesite and black graphite. It is...


Soapstone is a type of talc-schist metamorphic rock. Also other naming’s are steatite or soaprock. The composed primarily of talc, with varying amount of...
Garnetite (garnet skarn)


Skarn is coarse-grained metamorphic rocks that forms by a metasomatism. Also called tactites. Skarn tend to be rich in calcium-magnesium-iron-manganese-aluminium silicate minerals that also...


A granular metamorphic rock, marble is derived from limestone or dolomite. It consists of a mass of interlocking grains of calcite or the mineral dolomite. Marbles form when limestone buried deep in the older layers of Earth’s crust is subjected to heat and pressure from thick layers of overlying sediments.


Quartzite is a nonfoliated metamorphic rock composed almost absolutely of quartz. It paperwork while a quartz-rich sandstone is altered via the warmth, pressure, and chemical interest of metamorphism. These situations recrystallize the sand grains and the silica cement that binds them collectively. The result is a network of interlocking quartz grains of incredible power.
