不整合分类研究进展与新型分类方案

TYPES OF UNCONFORMITIES AND THEIR CLASSIFICATION

总结了前人对不整合类型的划分工作和不整合形态特点,在此基础之上,根据不整合的成因机制和不整合形态的主控因素,提出了新型不整合分类方案,将不整合分为七个大类,包括削截不整合、褶曲不整合、底辟不整合、震积不整合、古岩溶不整合、超覆不整合和假整合,并进一步细分为13个亚类。新型的不整合分类考虑了震积作用研究等最新的地质学进展,吸收了许多有益成果,扩充了不整合类型,更加关注盆地的自身特点,通过剔除重复类型等方法,使不整合分类方案更加完备,具有较高的科学性和实用性。文中还以国内外有关油田为例分析了不整合类型基本特征。

This paper summarizes different types of unconformities, their characteristics, and their origins. According to their origins and factors controlling their development, they can be divided into seven types： truncation unconformity, fold unconformity, diapirism unconformity, seismic unconformity, palaeokarst unconformity, overlap unconformity, and parallel unconformity. The types can be further subdivided to thirteen subtypes. The new classification considers recent developments and removes redundant types in order to make this classification more efficient and applicable.
