2007/12/31· Best Answer: sedimentary rocks are caused by lots of grains being compressed together. Igneous rock is caused by lava above ground, and metamorphic is when either type of rock changes due to high ...
Lowgrade metamorphism takes place at temperatures between about 200 to 320 o C, and relatively low pressure. Low grade metamorphic rocks are generally characterized by an abundance of hydrous minerals. With ...
I am a student at Oxon Hill High School in Maryland and I am doing a project on the rock cycle. The metamorphic rock we selected was marble, which is formed from limestone and contains dolomite and calcite as the two main ...
They are found all over the world and are quite common in sedimentary rock sequences. Dolomite is a common sedimentary rockforming mineral that can be found in massive beds known as dolomites. These beds may be several ...
