摘　　要：本文拟以贵州织金地区戈仲伍组矿体与下伏地层关系为研究对象,针对传统下寒武统戈仲伍组与下伏震旦系灯影组整合接触的学说,以该地区针对磷块岩矿床的勘查实例为依据,发现其接触界面表现为不整合面之下地层被截切、不整合面上风化壳存在现象,故本文认为织金地区曾在寒武纪梅树村期之前整体上隆,并短暂出露地表遭受剥蚀,以此对黔中古陆矿体形成的雏形进行探究分析。In this paper, the relationship between the ore body and the underlying strata in the Gezhongwu Formation in the weaving area of Guizhou is taken as the object of study. According to the theory of the integrated contact between the traditional Cambrian Gouzhong Wu group and the lower Sinian Dengying Formation, The results show that the contact interface is characterized by the existence of the weathering crust on the unconformity of the strata under the unconformity. Therefore, this paper holds that the weaving area has been in the form of the Cambrian plum tree Long, and briefly exposed to the surface suffered erosion, in order to explore the formation of the ancient Chinese oak ore body shape analysis.
