Plutonism is the geologic theory that the igneous rocks forming the Earth originated from intrusive magmatic activity, with a continuing gradual process of weathering and erosion wearing away rocks, which were then deposited on the sea bed, re-formed into layers of sedimentary rock by heat and pressure, and raised again.
Plutonism is the process by which magma rises through the crust and crystallizes as an intrusive igneous rock beneath the Earth’s surface. Pluton is a generic word for any igneous intrusive rock body.
Based on Hutton’s theory of plutonism, processes that create and arrange rocks into the current landscape are driven by heat concealed within Earth’s interior. Another fundamental aspect of Hutton’s theory of plutonism is that rock-forming processes are constant and slow.
5 days ago · plutonism. Quick Reference. A theory of the formation of the Earth, prominently advocated by Hutton, and based on cycles of the growth, decay and regeneration of land masses. The forces involved in these cycles were heat and gravity, the heat deriving from subterranean fires.
In Earth sciences: Earth history according to Werner and James Hutton. …James Hutton, leader of the Plutonists, viewed Earth as a dynamic body that functions as a heat machine. Streams wear down the continents and deposit their waste in the sea.
