河南付金川金红石矿床地质特征及远景评价

为开发利用付金川金红石矿，综合分析了矿区以往地质资料，并在实地勘探、样品测试和重点地段综合研究的基础上，从区域成矿地质背景、矿区地质特征、矿床地质特征、金红石赋存状态、矿床成因等方面对付金川金红石矿床进行了综合研究，总结了找矿标志，并从成矿潜力、矿石加工技术、矿床开采技术条件、矿产经济效益等方面评价了矿床综合利用远景。研究表明：①付金川金红石矿为位于留山-羊册金红石矿带上的具有大型规模的层状变质火山岩型矿床，赋存于中元古界左老庄岩组地层中，矿体受地层控制，展布稳定；②含矿岩石主要为斜长角闪片岩和黑（二）云斜长片岩，矿石多为粗粒级易选型金红石；③矿床成矿潜力大，矿石加工性能良好，矿床开采技术条件简单，矿产经济效益较好，具有较好的开发利用远景。

Geological Characteristics and Prospective Evaluation of Fujinchuan Rutile Deposit in Henan Province

In order to develop and utilize Fujinchuan Rutile Mine,the alrealy existed geological data of the mining area is analyzed comprehensively,and based on the results of field exploration,sample test and the comprehensive study results of some key sections,Fujinchuan Rutile Deposit is studied systematically from the five aspects of regional metallogenic geological background,geological characteristics of the mining area,geological characteristics of the deposit,rutile occurrence mode and deposit genesis,prospecting indicators of the deposit are summarized,besides that,comprehensive utilization prospective of the deposit is evaluated from the four aspects of metallogenic potential,ore processing technique,mining technical conditions of the deposit and mineral economic benefits.The study results indicated that:①Fujinchuan Rutile Deposit belongs to stratified volcanic rock deposit with large scale on Liushan-Yangce rutile ore belt,the deposit occurs in Middle Proterozoic Zuolaozhuang Formation,and it is controlled by strata and its distribution state is table;②the ore-bearing rocks is mainly for plagioclase amphibole schist and biotite plagioclase schist,and which is mainly for coarse fraction and amenable to ore dressing;③the metallogenic potential is great,the ore processing property is good,mining technical conditions of the deposit is simple,mineral economic benefits of the deposit is ideal,therefore,development and utilization perspective of the deposit is good.
