From Wikipedia, the free encyclopedia
A massif in Ukraine

Amassif(/mæˈsf,ˈmæsɪf/) is a principalmountainmass,[1]such as a compact portion of amountain range,containing one or moresummits(e.g. France'sMassif Central). Inmountaineeringliterature, a massif is frequently used to denote the main mass of an individual mountain.

As a purely scientific term ingeology,however, a "massif" is separately and more specifically defined as a section of a planet'scrustthat is demarcated byfaultsorflexures.In themovementof the crust, a massif tends to retain its internal structure while being displaced as a whole. A massif is a smaller structural unit than atectonic plateand is considered the fourth-largest driving force ingeomorphology.[2]

The word "massif" originates from French (in which the word 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. TheFace on Marsis an example of an extraterrestrial massif.[3]Massifs may also form underwater, as with theAtlantis Massif.[4]
