WebContinental collision is an intrinsic feature of plate tectonics. The closure of an oceanic basin leads to the onset of subduction of buoyant continental material, which slows down and eventually stops the subduction process. In nat-ural cases, evidence of advancing margins has been recog-nized in continental collision zones such as India-Eurasia WebAug 22, 2008 · As early as the 1920s, Argand ( 1) postulated that the plateau formed as the result of collision and postcollisional convergence of the Indian subcontinent with Eurasia, causing shortening and thickening of the crust to ∼80 km and producing the magnificent mountain ranges of the Himalaya, Karakorum, and Tien Shan.
