What process changes the grain size of a metamorphic rock? What kind of igneous rock usually contains large crystals? How does subduction produce magma? How do extrusive igneous rocks form? What causes rock to change in regional metamorphism?
What is transportation in the rock cycle? What type of rock forms when magma cools? What process causes igneous rock to transform into metamorphic rock? Which type of metamorphism turns peridotite to serpentine? Who discovered the rock cycle?
Alkali magmatites from the 94 Ma old Magnet Cove Igneous Complex (MCIC) include aphanites and phanerites of insufficient mineralogical and chemical characterization. Main reasons are the small grain size of the minerals and the presence of a hydrothermal alteration mineralogy. Both make the ...
Diamonds are most often found in kimberlite pipes, carrot-shaped, volcanic rock formations. Diamonds started out as carbon that crystallized deep in the earth under great pressure and temperature. Volcanic activity brought the diamonds to the Earth’s surface in kimberlite magma. Erosion of kimberlite...
There are three main types of rock — igneous, sedimentary and metamorphic — with varying mineral mixes depending on where and how the rock came to be. Igneous rocks — which form as magma solidifies either deep within Earth or at the surface after a volcanic eruption, for example — c...

Metamorphic rocksform out of other rocks. They are predominantly sedimentary or igneous rocks that have undergone changes as a result of extreme pressure and heat. The name defines the formation whereby ‘meta’ means change and ‘morph’ means ‘form.’ Large tectonic movements and magma intrusion...
The Earth’s mantle, including the transition zone, consists primarily of peridotite, an ultramafic igneous rock. The mantle was divided into the upper mantle, transition zone, and lower mantle as a result of sudden seismic-velocity discontinuities at depths of 410 and 660 km. This is thought...
What processes can change igneous rock into sedimentary rock? What is formed by glacial erosion? What is the process that changes the shape of rocks? What are the major processes of the rock cycle? Which Earth systems interact with the geosphere to cause erosion?
