  2. Regolith-hosted rare earth element deposits - Wikipedia

    en.wikipedia.org/wiki/Regolith-hosted_rare_earth...

    An overview of one of the regolith-hosted rare earth element deposits (a type of Rare Earth Element mine) in South China [1]. Regolith-hosted rare earth element deposits (also known as ion-adsorption deposits) are rare-earth element (REE) ores in decomposed rocks that are formed by intense weathering of REE-rich parental rocks (e.g. granite, tuff etc.) in subtropical areas.

    en.wikipedia.org/wiki/Magmatic_water

    Rhyolitic magma is felsic and the most abundant in silica, potassium, and sodium but the lowest in iron, magnesium, and calcium. [1] [3] The silica composition of rhyolitic magma ranges from 65-75 wt.%. [1] It forms in the lowest temperature range, from about 1200 °F to 1470 °F. [1], [3] Rhyolitic magma has the highest viscosity and gas ...

  4. Plutonism - Wikipedia

    en.wikipedia.org/wiki/Plutonism

    Plutonism is the geologic theory that the igneous rocks forming the Earth originated from intrusive magmatic activity, with a continuing gradual process of weathering and erosion wearing away rocks, which were then deposited on the sea bed, re-formed into layers of sedimentary rock by heat and pressure, and raised again.

  8. Magma - Wikipedia

    en.wikipedia.org/wiki/Magma

    Magma that cools slowly within a magma chamber usually ends up forming bodies of plutonic rocks such as gabbro, diorite and granite, depending upon the composition of the magma. Alternatively, if the magma is erupted it forms volcanic rocks such as basalt , andesite and rhyolite (the extrusive equivalents of gabbro, diorite and granite ...
