Granitic batholith

WebJun 5, 2024 · The batholith shows extreme variation in chemistry, while having limited mineralogical variation, and seems to be the world’s most heterogeneous granitic mass. The Nd model ages of ~2 Ga suggest that Eburnean rocks of the former magmatic arc, structurally overlain by the accretionary wedge, are the most probable magma sources. The Sierra batholith was formed when the Farallon Plate subducted below the North American Plate. The resultant molten rock rose through the Earth's crust over the span of 100 Ma, forming several plutons, or a chain of volcanoes if the magma reached the surface. Most of the granitic rocks formed between 105 and 85 Ma, during the Cretaceous, with pluton formation ending around about 70 Ma. Erosion from 85 until 15 Ma removed the volcanic rocks and exposed the g…
