Massif

From Wikipedia, the free encyclopedia

In geology, a massif is a section of a planet's crust that is demarcated by faults or flexures. In the movement of the crust, a massif tends to retain its internal structure while being displaced as a whole. The term is also used to refer to a group of mountains formed by such a structure. The massif is a smaller structural unit of the crust than a tectonic plate.

The word is taken from French (which also means "massive"), where it is used to refer to a large mountain mass or compact group of connected mountains forming an independent portion of a range. One of the most notable European examples of a massif is the Massif Central of the Auvergne region of France.

In mountaineering and climbing literature, a massif is frequently used to denote the main mass of an individual mountain.

The Face on Mars is also called a massif, or alternatively, an albedo feature.[1]
