| 中文摘要: |
| 舞钢市杨树湾石墨矿床位于灵宝—鲁山—舞阳太华群石墨成矿带东端,新太古界太华群杨树湾组地层是石墨矿体含矿层位,含矿岩石主要为含石墨黑云斜长片麻岩,少量为含石墨(透辉石)大理岩。矿石类型以片麻岩型为主,深部少量为(透辉石)大理岩型。石墨矿床成因类型为典型的沉积变质型矿床,区内石墨矿的形成受含矿地层原岩性质、变质作用和区域构造控制。研究认为矿体深部及外围仍有较大的找矿空间,可继续沿矿体延伸方向往深部和矿区外围追寻隐伏矿体,在矿区西北部的叶县辛店一带的杨树湾含矿岩系出露地带是寻找石墨矿的有利地段。 |
| 英文摘要: |
| The Yangshuwan graphite mine in Wugang City is located at the eastern end of the graphite metallogenic belt named Lingbao-Lushan-Wuyang Taihua group. Its ore-bearing stratum is the Yangshuwan formation of the Taihua group of the Neo-Archean, and ore-bearing rocks are mainly graphite-bearing biotite plagiogneiss, and a small amount of graphite-bearing (diopside) marble,most of the ore types are gneiss type, and a small amount in the deep part is (diopside) marble type. In addition, the genetic type of this graphite deposit is a typical sedimentary metamorphic deposit.The graphite ore formation is controlled by its protolith property, metamorphism and regional structures.This study believes that there is still a large space for prospecting in the deep part and the periphery of the ore body, and it is also possible to continue to search for the hidden ore body along the extension direction of the ore body to the deep part and the periphery of the mining area. And it is considered that the outcropping zone of Yangshuwan ore-bearing rock series in Xindian, Yexian County in the northwest of the mining area is a favorable area for finding graphite deposits. |
