massif

This term describes a geological entity characterized by its solidity and resistance to the forces of erosion. It evokes an image of a singular, imposing block of stone or a tightly clustered group of peaks that stand as a unified structural whole rather than a loose chain of mountains. In technical geological contexts, it refers specifically to a large body of rock that is distinct from the surrounding strata. It is used primarily in geography and geology, carrying a formal and descriptive tone.
