| 中文摘要: |
| 在开展姚家矿区铁矿资源储量(240万t)核实的基础上,通过分析赣中铁矿区已有研究成果, 重点通过对姚家铁矿区域地质特征、矿区地质特征、矿体特征、矿石特征及同位素分析研究,认为姚家铁矿产于洪山组地层中,处在钦杭成矿带赣中(新余式)铁矿区的北东段,属沉积变质型铁矿。通过研究发现,该矿床的成因分为3个阶段:海底喷发沉积期,区域变质作用成矿期,后期褶皱改造保存期。 |
| 英文摘要: |
| This paper is based on the verification of iron ore resources reserves in Yaojia mining area, through careful analysis of existing research results in Jiangxi iron mining area, focusing on the regional geological characteristics, mining geological characteristics, ore body characteristics, ore characteristics and isotope analysis of Yaojia iron mine. It shows that the Yaojia iron ore is produced in the Hongshan Formation, located in the north-eastern section of the central Jiangxi (Xinyu style) iron ore area in the Qinhang metallogenic belt, and belongs to a sedimentary metamorphic iron ore. It is found that the genesis of the deposit can be divided into three stages:submarine eruption and deposition, regional metamorphism and mineralization, and later fold transformation and preservation. |
