Pluton geology definition
WebbPlutonic rock bodies are of many different sizes and shapes, all generically called plutons. Large plutonic bodies include batholiths, plutons, lopoliths, and laccoliths. Batholiths form by multiple intrusions in the same region. Sheet-like intrusions include sills and dikes. WebbLes plutons sont le devenir des magmas lorsqu'ils sont retenus en profondeur dans la croûte, par opposition aux cônes volcaniques, qui sont le résultat de la remontée en surface de ces derniers.
