31. The oceanic crust in front of India slid under Eurasia, pushing up the Tibetan plateau. 32. This in turn produced thicker oceanic crust and thicker regions of underlying depleted lithospheric mantle. 33. Oceanic crust can be subducted, while continental crust cannot.34. This resulted in the thickening of the oceanic crust in the Pacific and Indian Oceans. 35. New oceanic crust moves away from the spreading center. 36. Enrichment in Ba, Sr and alkalis may result from a component derived from subducted oceanic crust . 37. These differences result from processes that occur during the subduction of oceanic crust and mantle lithosphere. 38. Oceanic crust is referred to as a metabasite.39. Plates include both oceanic crust and continental crust. 40. The Scotia Plate is made of oceanic crust and fragments now distributed around the Scotia Sea.
