赣湘地区的变质核杂岩和变质穹窿构造中,晚期脆性断裂与早期低序次韧性构造间存在着明显的相关联系。
In the metamorphic core complex (MCC) and the metamorphic arch, Jiangxi and Hunan area, there is an obvious correlation between the late brittle fault and the early subordinate ductile structure.
早期的韧性变形发生在角闪岩相变质作用条件下,晚期的脆韧性变形发生在绿片岩相变质作用条件下。
The earlier ductile deformation took place under the condition of amphibolite facies and the later transitional ductile-brittle deformation under the condition of greenschist facies.
部分熔融过程发生于鲜水河断裂早期活动的剪切熔融过程,岩浆作用之前可能发生过强烈挤压而产生了高压变质作用。
The partial melting was probably produced with early shear inching process of Xianshuihe fault belt, also occurred strong compression before the magmatism to produce the high-pressure metamorphism.
