在河南省南阳地区北部,有一条宽几公里至几十公里、长百余公里,呈北西～南东方向展布的萤石矿化带,地表出露数百个矿点,多年来为群众采挖,供国内外许多厂家利用,但尚未引起地质学界的注意。笔者通过现场考察和岩相、矿相、矿物标志的研究,结合矿石可选性试验资料认为:这是国内罕见的沉积变质型萤石矿带,故特以南召——方城矿段萤石矿化特征介绍如下,以就正于学术界的同行。一.含矿建造与岩性组合萤石赋存于下元古界秦岭群陶
In the northern part of Nanyang in Henan Province, there is a fluorite mineralization belt ranging from kilometers to tens of kilometers in width and over a hundred kilometers in length, spreading from north to south to the east and southeast. There are hundreds of ore spots on the earth’s surface, Excavation, for many domestic and foreign manufacturers to use, but has not yet attracted the attention of geology. Through field investigation and research on lithofacies, mineral facies and mineral signs, the authors believe that this is a rare sedimentary metamorphic fluorite ore belt in China, The mineralization features are described below, just as the academic peers. One ore-bearing construction and lithology combination of fluorite hosted in the lower Proterozoic Qinling Group Tao
