豫陕交界地区钾长石矿产地质特征及开发前景

Characteristics and development prospect of potash feldspar ore in area on the boundary between Henan and Shaanxi

本文研究证明区内有南、北两条钾长石成矿带,其产出形态、矿化特征、矿石类型均有差异,且导致了它们在工业应用上的不同。区内矿体以岩脉或岩株产出,有红色、浅红色、白色3种矿石。白色矿石富钾低铁,达到国标一级品,其余矿石为二级以下品级,均具有一定的销售市场。从全国的供需形势分析,今后钾长石矿产品市场前景广阔,而区内钾长石资源进一步找矿的潜力仍然很大。

The author studies the output appearance,mineralized characteristics and ore type of the south and north zone of potash feldspar ore in the area on the boundary between Henan and Shaanxi.Their differences make their application different in industry.The ore-bodies were formed as vein and stock.The ores are red,light-red and white.The white ores bearing-low iron are pay-grade,the orthers are second-grade.They have the certain sale.According to analysis of the whole providing and demanding,the potash feldspar ore′s market is foreground.Further searching potash feldspar resources is very potential.
