Dolomite: A sedimentary rock known as dolostone or ...

What is Dolomite? Dolomite, also known as "dolostone" and "dolomite rock," is a sedimentary rock composed primarily of the mineral dolomite, CaMg(CO 3) 2.Dolomite is found in sedimentary basins worldwide. It is thought to form by the postdepositional alteration of lime mud and limestone by magnesium-rich groundwater.. Dolomite and limestone are very similar rocks.

what is metamorphic rock - tradedigital.slz.br

Metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). Hence, metamorphic regions are also regions of former or recent intense orogeny . They occur when sedimentary and igneous rocks become changed, or metamorphosed, by conditions underground.

Regional metamorphism is associated with a large area of metamorphism, formed by the pressure and heat of colliding plates. Contact metamorphism is when the heat of magma/lava touches rocks, causing a small area to change into metamorphic rocks. Contact metamorphism will occur on the outside edges of igneous intrusions.

Basics--Metamorphic Rocks Table

2013-5-31  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.
