皖南天井山金矿床地质-地球化学特征及找矿前景

皖南地区山高林密,地质工作条件差,基础地质工作相对还很薄弱,金矿的找寻工作一直没有取得大的突破.本文选取皖南休宁县天井山金矿为切入点,对该矿床地质、地球化学特征进行了分析,基本理清了本区与金成矿相关的各种因素,对矿床成因进行了剖析,并对其找矿前景作了探讨.系统统计分析区内地层、岩浆岩、矿石的主微量元素、稀土元素特征,讨...

Geochemical characteristics and prospecting in the Tianjingshan gold deposit, South Anhui

Due to high mountain conditions and high-dense covering of forests in south Anhui, the geological survey is difficult and geological exploration is relative weak . The breakthough of gold- prosepcting has not been achieved. This study focuses on the Tianjingshan gold deposit in south Anhui by means of geological survey, element analysis and statistics on geochemical database of sedimentary rocks, magmatic rocks and gold deposits around the deposit. The systematic statistics on major and trace elements has been done, discussing relationship between gold formation and geologic strata, magmatic rocks and regional structure in both Tianjingshan gold deposit and Jinshan ultra-scale gold deposit (Jiangxi Province). We established engineering in this deposit and obtained good ore bodies in Xiaohe gold distirct in the Tianjingshan gold mine, proving that this region is good for forming and prospecting large-scale gold deposit in south Anhui.
