Metamorphic Rock Facts

If it did melt that would mean that either igneous or sedimentary rocks would form Interesting Metamorphic Rock Facts There are rocks called foliated rocks This is a type of rock with parallel bands of grain Wow that sure is weird Then there are non-foliated rocks This is a type of metamorphic rock that has no bands of grain Get price

Rocks

Intrusive igneous rocks cool slowly below the Earth's surface and have larger crystals Rocks made up of dense dark-colored minerals such as olivine pyroxene amphibole and plagioclase are called mafic igneous rocks Lighter-colored less dense minerals including quartz mica and feldspar make up felsic igneous rocks Get price

Igneous Rocks

Intrusive igneous rocks crystallize below Earth's surface and the slow cooling that occurs there allows large crystals to form Examples of intrusive igneous rocks are diorite gabbro granite pegmatite and peridotite Extrusive igneous rocks erupt onto the surface where they cool quickly to form small crystals Some cool so quickly that Get price
