摘要
本文综述了同生断层控矿研究的进展，并结合在粤北地区的研究，论述了伸展及走滑盆地中同生断层的形成机制、特征和在盆地流体迁移和聚集中的作用以及与层控Ｐｂ－Ｚｎ（－Ｂａ－Ｃｕ－Ａｇ）等矿床的时空关系，认为沉积盆地中不同成因类型的层控矿床是盆地不同演化阶段的产物，成矿时空分异受同生断层和盆地流体系统的控制。
On the basis of the former study and by taking YueBei district as an example,the formation and characteristics of synsedimentary faults in extensional and strike-slip basin, the affection of the faults on the movement, the collection of basinal fluids (ore fluids) and the time and space relations between the synsedimentary faults and stratabound Ph-Zn (-BaBaCu-Ag) deposits are expounded in this paper. Authors consider that the different genetic types of stratabound ore deposits formed in different evolutionary stages of basin and the metallogenic differentiations in time and space are controlled by the synsedimentary faults and basinal fluid systems.Finally, some questions are discussed.
