Magma, known as lava when expelled from volcanoes, solidifies quickly when in contact with the atmosphere, and is known as extrusive rock. This stage can affect any of the three main types of rock. Metamorphic transition stage Metamorphic rocks are formed when rocks are open to soaring ...

Filtration is the process of separating out solids from liquids by passing them through a medium that obstructs the solids from passing while the liquid passes. The desired chemical constituents can be either the separated solids or the liquid the passed through the filters. Filtration can either ...
Napalm is an incendiary mixture of a gelling agent and a compatible volatile petrochemical. The name is a portmanteau of two of the constituents of the original thickening and gelling agents: aluminium naphthenate and aluminum salts of coconut fatty acids sold by Metasap under the trade name Alumi...
What is a xenolith and how are they formed? The rock that forms from cooled magma is called igneous rock. Xenoliths are different types of rock embedded in igneous rock. ... As the molten material rises,it tears off bits and pieces of the magma pipe in which it is traveling. These bi...
Other factors are the homogenization and distribution of the constituents in the natural sample, grain size, the organic matter content, the porosity, compaction, water content, the degree of alteration of the minerals, their crystallinity, etc. (e.g., Crowley, 1986; García-Rivas et al., 201...

What do we see where rocks have undergone metamorphism(变质岩)
classification of rocks is based on two criteria,TEXTURE and COMPOSITION. The texture has to do with the sizes and shapes of mineral grains and other constituents in a rock, and how these sizes and shapes relate to each other. Such factors are controlled by the process which formed the rock...
