The Evolution of Ore‐forming Fluid of Maoping Lead‐Zinc Deposit, Zhaotong in Northeast Yunnan: the Evidence of Sphalerite‐hosted Fluid Inclusions

The Maoping zinc-lead deposit is one of the typical zinc-lead deposits in Northeast Yunnan District, located in the sagged Yunnan basin at the middle end of the Yangtze platform. This district has been the focus of extensive and intensive research for more than 40 years on its geology, geochemistry, geochronology, tectonics, ore-genesis and ore-prospecting. As ore-prospecting on deep orebody at recent years, the deposit has been a large-type one in this district. Prior to this study, many papers have been published on ore-prospecting, geology, tectonics, fluid inclusion studies of the Maoping lead-zinc deposit (Zou et al., 2004; Han et al., 2007; Hu et al., 2003; Hu Bin, 2004; Wang et al., 2009; Shentu et al., 2011). The fluid inclusion study was restricted to quartz, dolomite and calcite which paragenetic with ore minerals (Han et al., 2007).
