| 中文摘要: |
| 通过搜集西华山地区地质勘查成果资料,结合野外地质调查工作,进行综合研究分析。结果表明,西华山地区石墨矿主要赋矿地层为长城系海原岩群园河岩组,其次为西华山岩组,严格受地层层位控制；矿石为含石墨白云母石英片岩、含石墨石英片岩及含石墨大理岩。矿体呈层状、似层状,连续较好。找矿标志为黑色含炭质片岩、构造转折端、褐铁矿化、物探异常等。得到的结论为该地区石墨矿地质勘查工作程度低, 含石墨地层分布广泛,初步判断马场—簸箕掌具良好的找矿前景。 |
| 英文摘要: |
| Using data and documents acquired through geological survey, in combination with field investigation, this work studied the Haiyuan rock group crystalized graphite in Xihua mountain area. The results show that the graphite formation in the Xihua mountain area is primarily distributed in Heyuan rock formation of Changcheng Haiyuan rock group, followed by the Xihua rock group, which is strictly controlled by strata. The ores are graphite-bearing muscovite schist, graphite-bearing quartz schist and graphite-bearing marble. The orebody has good layered, stratiform-like structure and good continuity. Prospecting indicators include black carbonaceous schist, structural turning point, ferritization, geophysical anomaly, etc. It is concluded that the geological exploration of graphite deposits in this area is poor and graphite-bearing strata are widely distributed. The Machang—Bojizhang area has a good prospecting potential for graphite. |
