摘　　要：河南省方城县青山透辉石矿床大地构造位置处于华北陆块南缘崤山—鲁山拱褶断束东端,属矽卡岩型矿床,成矿时代为燕山晚期,受燕山晚期黑云母花岗岩和汝阳群北大尖组中的白云质大理岩夹白云石大理岩层的双重控制。详细分析了该矿床地质特征及开发利用前景,认为该矿床具有规模大、矿体形态简单、矿石类型单一、矿物成分简单、品位高等特点,并且矿床Si O2、Mg O和Ca O主要成分接近透辉石的理论化学成分,Fe O、Fe2O3和Ti O2有害组分含量低,在陶瓷、电瓷、玻璃、铸石、冶金保护渣和有色金属铸型用砂等方面具有广阔的应用前景。Qingshan diopside deposit in Fangcheng County,Henan Province is tectonically located in the east end of Xiaoshan-Lushan arch fold fault bundle at the Southern Margin of the North China Craton.The deposit belogns to skarn type deposit,and its minerogenetic epoch belongs to Late Yanshanian.The deposit is controlled by Late Yanshanian biotite granite and dolomitic marble in Beidajian Group of Ruyang Group.Based on some related geological working results,the geological characteristics and development and utilization prospects of the deposit are studied.The results show that the deposit is characterized by large scale,simple form of ore-body,simple form of ore,simple composition of minerals and high grade,its main components （SiO 2,MgO and CaO） is close to the theoretical chemical compositon of diopside and its harmful component contents is very low.Therefore,the development and utilization prospects of the deposit in ceramic, porcelain, glass, cast stone, metallurgical covering slag and nonferrous metal cast sand is good.
