占山元铁矿地质特征及成因初探

Primary Investigation on the Geological Features and Formation Factors of Zhanshanyuan iron mine

本文在野外地质调查和前人资料研究基础上,通过对含铁石英岩建造、矿体地质特征及矿石特征分析研究,占山元铁矿赋存于洪山群地层的含铁岩系中,属沉积变质型铁矿,为江西省东部震旦系沉积变质铁矿（新余式铁矿）带的北东段。该矿床的成因初步分为三个阶段：海底裂谷火山喷发沉积形成,区域变质作用成矿,后经褶皱改造保存。

Geological survey in the field and on the basis of previous research data, through the construction of iron ore quartzite geological characteristics and ore characteristics analysis, research, Zhanshan yuan Occurrence iron ore rock series Yuhong Hills formation in sedimentary metamorphic iron ore, eastern Jiangxi Province, North east Sinian sedimentary metamorphic iron ore （iron ore Xinyu formula） band. Cause of the initial deposit is divided into three stages： the submarine volcanic eruption rift sedimentary formation, mineralization regional metamorphism, save by fold transformation.
