Magma chemistry
Web5 dec. 2024 · Chemically, “magma mixing” is driven by the mobility of chemical elements in the melt fractions of the two magmas (e.g., Lesher 1990; Baker 1990 ). Linear variations in inter-elemental plots for a set of rock samples have long been considered as the sole evidence for the occurrence of magma mixing (e.g., Fourcade and Allegre 1981 ). Magma (from Ancient Greek μάγμα (mágma) 'thick unguent') is the molten or semi-molten natural material from which all igneous rocks are formed. Magma is found beneath the surface of the Earth, and evidence of magmatism has also been discovered on other terrestrial planets and some natural … Meer weergeven Magma consists of liquid rock that usually contains suspended solid crystals. As magma approaches the surface and the overburden pressure drops, dissolved gases bubble out of the liquid, so that magma near … Meer weergeven Most magmas are fully melted only for small parts of their histories.

Web6 dec. 2024 · Lava chemistry provides vital information on the underground sources of magma, eruptive conditions, temperature, and physical properties of lava flows. However, analytical techniques are typically slow, leaving chemical analysis of lava as a retrospective tool in the volcano sciences. Web11 jan. 2024 · Magma chambers are located where the heat and pressure are great enough to melt rock. These locations are at divergent or convergent plate boundaries or at hotpots. The chemistry of a magma determines the type of igneous rock it forms. The chemistry also determines how the magma moves.
