dolomite in metamorphic rock

Dolomite Rock

Dolomite or dolostone is a carbonate sedimentary rock containing more than 50% by weight of the mineral dolomite.Dolomite rock may contain calcite, but the content of calcite should not exceed 10% of the calcite-dolomite pair's content 3.. Dolomite in Northern Norway (Trollholmsund) which was once chalk, but the original material has been replaced with dolomite.

Dolomite vs Hornfels

Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight. Hornfels is a metamorphic rock formed by the contact between mudstone or other clay rich rock, and a hot igneous body, and represents a heat altered equivalent of the original rock. These rocks are composed of many distinct minerals.

Metamorphic Rock Types: Pictures and Descriptions

This type of metamorphic rock consists of recrystallized calcite (in limestone) or dolomite (in dolomite rock). In this hand specimen of Vermont marble, the crystals are small. For fine marble of the sort used in buildings and sculpture, the crystals are even smaller. The color of marble can range from the purest white to black, ranging through

How does a igneous rock turn into a metamorphic

Any rock (igneous, sedimentary, or metamorphic) can become a metamorphic rock. If rocks are buried deep in the Earth at high temperatures and pressures, they form new minerals and textures all without melting. If melting occurs, magma is formed, starting the rock cycle all over again.
