主动侵位 meaning in Chinese

forcible emplacement

Based on the analysis of thermal contact metamorphic aureoles , granitoid interior structure , quartz axis fabric and strain characters in the different rock unites of yuanshishan granitoid and its wall rocks , the emplacement mechanism of yanshishan granitoid was studied . the magmatic explictite dynamic was advanced in light of regional stress and magma dynamic research . those conclusion was synthesized to ascertain the emplacement mechanism - granitic magma ascended in dikes with the minimum critical width of the magma ascending channels about 2 . 213 . 88m and located in the core of yindianshan dome with the passive style of dyke explictite ; the later unite is a kind of multiple emplacement mechanism with the character of active emplacement of ballooning
同时运用岩浆动力学原理从另一个角度探讨其侵位驱动力。综上指出：经分凝后的活动性岩浆在深部侧向挤压和浮力的联合驱动下，沿深大断裂以最小临界宽度为2 . 213 . 88m的裂隙脉动上侵，整体以岩墙扩展的方式被动定位于银殿山穹窿的核部，但后期屋面前单元具有主动侵位的特点应为一种复合定位机制。
