求翻译：因此,大兴安岭北部的高原减薄是埃达克质岩从下地壳熔出与区域应力场发生转换的共同结果, 在拉伸应力场作用下, 地壳中先存的压剪性断裂重新活动, 沿北东向形成地壳断块,然后含有残余物榴辉岩的下地壳则深入软流圈, 促使地幔上涌, 下地壳地热梯度增加, 下地壳中成分不均匀的沉积岩部分熔融, 沿断裂形成早白垩世火山活动是什么意思？

Therefore, the thinning of the Daxinganling northern plateau is a common result of adakitic rocks from the lower crust to melt and the regional stress field conversion, compression and shear fracture under tensile stress field, the pre-existing crust re-activity, along North East to the formation of

Therefore, the plateau north of daxinganling is thin up to the quality rock from the crust to melt the regional stress field in the Common Results in tensile stress, a role in the first, the earth's crust is broken, the pressure to cut along the North East, to form a crust, and then the block contai

Therefore, north Daxinanling's plateau attenuates is the Egyptian Ducker nature crag melts from under earth's crust has the transformation common result with the region stress field, under the stretch stress field function, the pr

So, daxinganling Northern of Plateau reduction thin is adakitic mass rock from Xia crust melt out and regional stress field occurs conversion of common results, in stretch stress field role Xia, crust in the first save of pressure cut sexual fracture again activities, along North East to formed crus
