fine grained rock mexico

Obsidian is an igneous rock that forms when molten rock material cools so rapidly that atoms are unable to arrange themselves into a crystalline structure. It is an amorphous material known as a " mineraloid ." The result is a volcanic glass with a smooth uniform texture that breaks with a conchoidal fracture (see photo).

Being a very fine-grained sediment the porosity of shale is very low. Porosity is the empty space in a shale formation that can work as a reservoir for natural gas, oil, and water. For the measurement of porosity of the rock, one has to calculate the total porosity of the rock, which is total volume of the rock divided by total pore volume.

The magma, called lava when molten rock erupts on the surface, cools and solidifies almost instantly when it is exposed to the relatively cool temperature of the atmosphere. Quick cooling means that mineral crystals don't have much time to grow, so these rocks have a very fine-grained or even glassy texture. What are the 4 types of igneous rocks?

What is fine-grained rock called? Igneous rocks may be simply classified according to their chemical/mineral composition as felsic, intermediate, mafic, and ultramafic, and by texture or grain size: intrusive rocks are course grained (all crystals are visible to the naked eye) while extrusive rocks may be fine-grained (microscopic crystals) or ...

Fine grained rocks are called "extrusive" and are generally produced through volcanic eruptions. Granite and gabbro are examples of phaneritic igneous rocks. Fine grained rocks, where the individual grains are too small to see, are called aphanitic. Basalt is an example. The most common glassy rock is obsidian.
