摘要
本文分别对贵州北部、中部、东部选取代表矿床,重点研究代表矿床的矿物岩石特征,通过对研究区采集样品进行室内岩矿石显微镜研究,矿石及围岩中分别见大量玉髓、火山泥球、凝灰物质及生物碎屑,反映了其海底喷流带来物质及海底喷流导致的特殊沉积环境。
In the northern part,central part,eastern part of the province,representative deposits were selected,Research was focused on the mineral rock characteristics of the representative ore deposit,In the study area samples indoor rock ore microscopy studies were carried out. Respectively in the ore and surrounding rock,a lot of chalcedony,volcanic mud ball,tuff and bioclastic matter were discovered. It reflects the underwater jet material and the bottom of the sea spray flow were caused by the special sedimentary environment.
