Quick Summary

Continent-continent collision is a geological process where two continental plates converge, leading to significant crustal thickening and the formation of massive mountain ranges. This occurs when oceanic lithosphere between two continents is consumed through subduction, eventually bringing the continental landmasses into direct contact.12

Unlike oceanic crust, continental crust is buoyant and resists subduction. This resistance causes the colliding continents to crumple and deform, pushing the crust upward to create towering mountains with deep crustal roots. The Himalayas, formed by the collision of the Indian and Eurasian plates, are a prime example of this process. These collisions are finite events, meaning the volume of rock involved is not replenished, and over geological time, erosion will gradually wear down these mountains.134

Facies series
…whereas areas thought to reflect continent-continent collision are more typically distinguished by greenschist and amphibolite facies rocks (see also subduction zone). Still other regions, usually containing an abundance of intrusive igneous material, show associations of low-pressure greenschist, amphibolite, and granulite facies rocks. These observations led a Japanese petrologist, Akiho Miyashiro,…

As a result, young metamorphic belts aligned roughly parallel to the present-day continental margins (e.g., the Pacific margin) as well as older metamorphic belts are used to infer the geometries of the continental margins at…
