magmasandesitic
Magmasandesitic refers to magma or volcanic rock compositions that are intermediate in chemistry between mafic (basaltic) and felsic (granitic) types. This classification falls within the broader spectrum of igneous rock compositions, where magma is categorized based on its silica (SiO₂) content and mineralogy. Andesitic magma typically contains between 52% and 63% silica by weight, making it more viscous than basaltic magma but less so than rhyolitic or dacitic magma.
Andesitic magmas are commonly associated with subduction zone volcanism, particularly in regions where an oceanic plate
Andesitic lava flows are typically viscous, leading to explosive eruptions rather than effusive ones. The high
The study of andesitic magmas is crucial in understanding volcanic processes, plate tectonics, and the geochemical
