endogenic phenomenon
Quick Summary
Endogenic phenomena in geology refer to processes originating from within the Earth. These internal forces are responsible for the formation of igneous rocks, which are created from molten rock material called magma. Magma is generated in the asthenosphere, a layer of partially molten rock beneath the Earth's crust.
When magma cools and solidifies deep within the crust, it forms intrusive igneous rocks. If magma erupts onto the surface as lava, it forms extrusive igneous rocks. These internal processes, along with plate tectonics, are fundamental to shaping the Earth's surface, driving events like volcanism and the creation of mountain ranges.1234

gold processingMining and concentratingEndogenetic deposits frequently contain elemental gold that is highly disseminated within a base metal sulfide mineral. These deposits are mined, crushed and ground, and then concentrated first by gravity separation to recover coarse particles of native gold before being subjected to froth flotation to concentrate…
