摘要
伸展构造研究是在近代构造地质学理论的基础之上兴起的，变质核杂岩构造模式的建立，一方面对伸展构造的发展起到了重要的促进作用，另一方面，也需要在实践中不断地补充和完善。变质核杂岩是地壳纵向剖面上的较深层次地质信息的载体，在华南地区具有广泛的分布，显然可以作为华南地区了解深部、研究基底的“窗口”和“桥梁”。加强这方面的研究，对深部找矿将会起到相当重要的推动作用。伸展构造研究并不仅仅局限于构造与变形的范畴之内，而是与沉积作用、岩浆作用、变质作用和成才作用领域的研究结合，从而形成了一个自成体系的构造地质学研究新领域。
The rise of stretching tectonics is established on the basis of recent structural geology theo-ry,the establishment of metamorphic nucleus complex structural model on one hand plays an importantpromoting part to the development of stretching structure,on the other hand,it needs constant supple-ment and perfection in practise. Metamorphic nucleus complex is the carrier of comparatively deep geo-logical information in vertical section of the crust and has wide distribution in the erea of south CHi-na. Evidently,it can be taken as the‘key’to understanding the deep and studying the basement,Strengthening the study will play the important promoting role to the deep prospecting,The studyof stretching tectonics is not only limitted within the range of structure and metamorphism,but com-bine with the studies of sedimentation,magmatism,metamorphism and mineralization,thus form a newfield of tectonic geology of self-developing system.
