| 摘 要： | 石马杂岩体,为南京—镇江地区出露面积较大的燕山期花岗质杂岩体,具大量暗色、细粒辉石闪长质-石英闪长质岩石包体,岩浆动力学理论的应用和详细的岩相学,岩石地球化学研究表明,该杂岩体中的岩石包体是不同成分岩浆大规模对流、不均一混合机制驱动下形成的,在成因类型上属淬冷包体.

THE GENETIC RESEARCH ON ENCLAVES WITHIN SHIMA COMPLEX,ZHENJIANG |
| |
| Abstract: | Shima complex is one of the largest Yanshanian granitic complexes dis- tributed in Nanjing-Zhenjiang mountains.It contains plenty of dark,fine-grained pynoxene-dioritic and quartz-dioritic rock enclaves.Application of the magmatic dynamic theory and detailed study of petrography and petrochemistry indicate that these rock enclaves belong to quenched-type,which were formed by magma mingling and convection on a large scale. |
