In some areas of continental collision, the lower part of the thickened crust that results is interpreted to flow laterally, such as in the

Factors that can vary this behaviour include: water content, thickness, heat flow and strain-rate. 59: 71: 286: 222: 163: 27: 298: 261: 212: 202: 153: 143: 183:"Crustal rheology controls on the Tibetan plateau formation during India-Asia convergence" 91: 257: 198: 139: 217: 182: 158: 123: 341: 54:.
