织金地区石炭系白云岩地质

Geology of the Carboniferous Dolomite Rocks in Zhijin,Guizhou

本文就分布在织金地区的摆佐组结晶白云岩的岩性组合、沉积特征及厚度和区域分布情况，结合地球化学特征，讨论了它的区域对比及地层时限。认为分布在织金落水洞一三甲以南地区的摆佐组白云岩是成岩期后产物，并包含了黄龙组─马平组层位，推测它是一个跨越石炭系中上部的穿时地质体。

In this paper,there is a discussion on the regional stratigraphic correlation and the time-limit in Zhijin area,Guizhou,in terms of geology of the crystalline dolomite rocks of the Carboniferous Baizuo Formation, including the lithological associations, characteristics and thickness of sedimentation, and distribution of the stratum. In conclusion,it is suggested that the dolomite distributed in south of Luoshuidong-Sanjia in Zhijin County is a post-diagenetic product and a geologic body with diachronism from the mid to the lower Carboniferous because the Huanglong Formation and the Maping Formation are involved In it.
