摘要
黔北地区栖霞组发育着一种有着特殊构造的碳酸盐岩:眼球状灰岩,由"眼球"和"眼皮"组成。通过野外剖面、钻井岩心、镜下观察分析,对眼球状灰岩的岩石学特征进行了详细描述,微量元素分析表明"眼球"为富氧沉积,"眼皮"为缺氧沉积。综合分析表明,眼球状灰岩是由沉积作用和成岩作用共同作用形成的。
Qixia formation in northern Guizhou developed a special structure of carbonate rocks： eyeball-shaped limestones, by the ＂eyeball＂ and ＂eyelid＂ composition. Through the field profile, drilling core and microscopic observation and analysis, the petrological characteristics of the ocular limestone are described in detail. Trace element analysis shows that ＂eyeball＂ is an oxygen-rich sediment and ＂eyelid＂ is anoxic sediment. Comprehensive analysis shows that the ocular limestone is formed by sedimentation and diagenesis.
