摘要
从形态上将桂林融县组灰岩中鸟眼构造分为四种 :颗粒状鸟眼构造、长条状鸟眼构造、蠕虫状鸟眼构造和不规则状鸟眼构造 ,并阐述了它们各自的特征、共生情况以及在产状上与灰岩性质的关系 ;分析了鸟眼构造的成因 ,划分出 6种成因类型 ,深入阐明了各种类型的特征、形成环境和形成过程中的影响因素 ;指出了鸟眼构造所具有的多种地质意义。
WT5BZ]The birdeye structures of carbonate rocks in Rongxian Formation in Guilin has many new and special features. This paper identifies four types of birdeye structures according to their shape: granulated birdeye structure, striped birdeye structure,wormlike birdeye structure and irregular birdeye structure; elaborates their features, paragenesis and relationship with the carbonate rocks; analyzes their genesis and explains their formation environment and elements in detail; and points out various geological significance of birdeye structure.
