岩石圈-软流圈的作用带也是重要的岩浆源区，源区是以软流圈地幔为主，基本不含地壳组分。
The lithosphere-asthenosphere interaction zone is also a major component of the magma source, which consists predominantly of asthenospheric mantle and in the main contains no crustal component.
源区地幔具有HIMU性质，由软流圈地幔、脱水洋壳与残留岩石圈地幔混合组成，表现出富集的特征；
The source mantle shows the HIMU nature. The asthenosphere mantle, the dehydrated ocean shell and remaining the ancient enrichmental mantle had mixed to form the source.
而下地壳拆沉是由于下地壳加厚使下地壳密度增加引起的，还要求其下刚性的岩石圈地幔转变成塑性的软流圈地幔才有可能发生。
And CLCD is caused by the crust thickening to increase the crust "s density, and require the underlying lithosphere mantle to change from rigidity into plasticity."
软流圈地球中地幔的一个区域，在岩石圈之下，包括几百公里可变形的岩石。
A zone of the earth's mantle that lies beneath the lithosphere and consists of several hundred kilometers of deformable rock.
我们初步认为，该区深部岩石圈MORB -OIB地幔可能是软流圈置换古岩石圈地幔而增生形成的。
It is tentatively suggested that the lower lithosphere MORB-OIB mantle is recently accreted since the paleo-lithosphere mantle was replaced by the abnormal asthenosphere.
