大梁子铅锌矿床位于扬子地台西南缘,是川滇黔铅锌矿集区赋存于震旦系灯影组上部碳酸盐岩内的典型矿床之一。矿体以北北西向断裂F1与F15为边界,产于“黑破带”内及其附近,远离黑破带矿化减弱(袁波等,2014)。“黑破带”与矿床成因的关系一直存在争议。本文在系统野外观察、流体包裹体显微测温、流体包裹体成分分析、硫同位素、有机碳含量研究的基础上,探讨“黑破带”与成矿的关
The Dalalizi lead-zinc deposit is located in the southwestern margin of the Yangtze platform. It is one of the typical deposits hosted by the lead-zinc concentrate in the Sichuan, Yunnan and Guizhou provinces in the Upper Carboniferous of the Sinian Dengying Formation. The ore body is bounded by F1 northbound and northwesterly faults F1 and F15 and is produced in and near the “black belt” and weakened its mineralization away from the black belt (Yuan et al., 2014). “Black broken belt ” and the relationship between the cause of the deposit has been controversial. Based on the systematic field observation, microscopic temperature measurement of fluid inclusions, composition analysis of fluid inclusions, sulfur isotope and organic carbon content, this paper discusses the relationship between the “black belt” and the metallogenic potential
