Web1 day ago · 1.Introduction. Potassium (K) is a large ion incompatible lithophile element and the eighth most abundant element in the Earth's crust (McDonough and Sun, 1995).Due to its distinct incompatibility during melting and mobility in melts/fluids, K has been considered as an important chemical proxy of planetary formation and evolution, crust-mantle … WebMay 8, 2024 · Only a very small portion (<5%) of the rock in magmatic source areas is thought to be liquid. Partial melts migrate upward from their source areas to intermediate staging areas, or magma chambers, in the middle and upper crust before erupting from volcanoes, or cooling to form intrusive igneous plutons.
