摘要: 眼球状石灰岩是华南地区中二叠统常见的一种碳酸盐岩岩石类型,由“眼球”和“眼皮”组成,广泛分布于中二叠统栖霞组下部和茅口组中—下部。关于眼球状石灰岩特征和成因的研究,已经取得了较为丰富的成果,笔者对这些成果进行了评述:对眼球状石灰岩的分布特征、岩石学特征及地球化学特征进行了总结;对其各种成因观点进行了讨论。在此基础上,阐述了眼球状石灰岩特征研究存在的争议,指出了下一步研究应关注的方面,尤其是在微观特征及地球化学特征方面,同时认为眼球状石灰岩的石油地质意义应该引起足够的重视。

Abstract: The eyeball-shaped limestone,which is composed of “eyeball”and “eyelid”,is a common type of carbonates with special structures in middle Permian in South China. It develops widely in the lower part of Qixia Formation and the middle-lower part of Maokou Formation. There are many research on the characteristics and origin of eyeball-shaped limestone,which is reviewed in detail in this paper. The distribution,petrological and geochemical characteristics of the eyeball-shaped limestones has been summarized. Besides,different viewpoints on the origin of this kind of eyeball-shaped limestones have been discussed. The controversies on the characteristics of eyeball-shaped limestones have been expounded,and the important research aspects in the future on the eyeball-shaped limestones have been pointed out,especially in the microscopic and geochemical characteristics. Finally it implies that the perspective of eyeball-shaped limestone on the petroleum geological significances should be paid enough attention

Key words: South China, Middle Permian, eyeball-shaped limestone, anoxic environment, upwelling
