鹤峰县石梁尖锌矿床地质特征及其成因分析

Geological Characteristics and Genesis Analysis of Shiliangjian Zinc Deposit in Hefeng County

鹤峰县石梁尖矿区位于上扬子古陆块南部被动边缘褶冲带八面山台地褶皱带长阳~秀山台褶束走马~东山峰背斜南西段之北西翼。锌矿体主要赋存于寒武系下统石龙洞组下段,主要呈透镜状产出。初步认为该锌矿床早期应属中低温热液充填型矿床,后经地表氧化形成氧化矿床。

The Shiliangjian mining area in Hefeng County is located in the north-west wing of the south-west segment of the Changyang-Xiushan platform fold belt in the Bamianshan platform fold belt on the passive margin of the southern upper Yangtze paleocontinent block. Zinc ore bodies occur mainly in the lower segment of Shilongdong Formation of the Lower Cambrian and are mainly lenticular. It is preliminarily considered that the zinc deposit belongs to the hydrothermal filling type at the early stage, and then oxidized to form an oxidized deposit by surface oxidation.
