摘　　要：通过对资料的解读研究,认为宁夏西华山地区具有形成晶质石墨矿良好的物源、温度、压力等成矿地质条件。在此基础上开展了晶质石墨矿地质调查工作,发现该区域石墨矿赋存于园河岩组含石墨云母石英片岩中,由于成矿温度较低,导致石墨片径较小,未形成具有工业开采价值的晶质石墨矿床。但通过此次研究,为后续在该区域开展晶质石墨找矿工作提供指导建议。Through the interpretation and research of data,it is believed that the Xihuashan area in Ningxia has favorable geological conditions for the formation of crystalline graphite deposits,including material sources,temperature,and pressure.On this basis,a geological survey of crystalline graphite deposits was carried out,and it was found that the graphite deposits in this area exist in the graphite mica quartz schist of the Yuanhe formation.Due to the low mineralization temperature,the graphite sheet diameter is small,and no crystalline graphite deposits with industrial mining value have been formed.But through this study,guidance and suggestions are provided for future exploration of crystalline graphite in the region.
