川中—川南过渡带香溪群地层划分与对比

以前川中、川西和川南的地层划分主要是依据岩性来进行的、是地方岩性地层系统划分、难于简单按所分段进行逐一对比、存在明显矛盾、造成过渡带井的地屋划分混乱。本文根据地震反射的等时性,从地震地层学,层序地层学,旋回地层学和岩石地层学的观点和方法,对川中—川南过渡带香溪群地层进行了统一的划分对比,理顺了川中—川南过渡带香溪群地层的对比关系,为进一步的地层研究提供了基础资料。

Stratigraphic Classification and Tracing of Xiangqi Group in Central Sichuan-South Sichuan Transitional Belt

According to the equitime character of seismic reflection and the characteristics of seismic atratigraphy, the authors have classified and traced the layres of Xiangqi Group in Central Sichuan-South Sichuan transitional belt, and provided the fundamental data for the further study of the layres.
