Element‐Combinations from Evidences of Tectono‐geochemistry of The Lekai Pb‐Zn Deposit in Northwestern Guizhou, China

The Pb-Zn metallogenic area in Northwest Guizhou is located in the southwest margin of the Yangtze block, which is an important part of the Sichuan-Yunnan -Guizhou (SYG) Pb-Zn metallogenic province. So far, studies (e.g. Qian, 2001; Jin, 2008; Zhou et al., 2013a) on this area have achieved numerous research achievements. Lekai Pb-Zn deposit is one of the newly discovered small deposits in this year. It is located at the Yinchang -po-Yunluhe ore-controlling fault zone in the northeastern segment of the NE-trending Luozehe fault. Wang (2004, 2008) made a preliminary study of this deposit, and thought it had a great prospecting potential. The research by Jin et al. (2016) and Zhang et al. (2016) showed that the ore-forming material is not from the ore-hosted strata. However, there are still some problems to be solved, such as the ore controlling regularity and tectono-geochemistry. Therefore, authors have studied tectono-geochemical features to find new ore bodies in this paper.
