44 results about "Massif" patented technology

In geology, a massif ( /mæˈsiːf/ or /ˈmæsɪf/) 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 also refers to a group of mountains formed by such a structure.
