该矿带长230km,宽3km,是南伊尔黄铁矿带的组成部分,1987-1988年完成了综合地球化学测量,进行了基岩、土壤、植物、水源采样。该区是由元古代变火山岩和变沉积岩组成,对成矿田南部的诺沃斯-科尔沃黄铁矿床区(50km~2)进行了大比例尺取样.黄铁矿储量达2亿吨,Cu、sn品位很高。这算欧洲最大的矿点,伴生组分有Pb、Zn、As、sb、Bi、In、Ca、Co、Se、Ag和Au,矿体埋藏深度>200m,对相邻地区进行了地球化学测量。应用了所有的地球化学方法,证明是非常有效的。
The ore belt is 230km long and 3km wide. It is part of the Naniwa pyrite belt. Comprehensive geochemical surveys were completed in 1987-1988 and bedrock, soil, plant and water samples were taken. This area is composed of Proterozoic volcanic rocks and metasediments, and large-scale sampling of the Novo-Corvo pyrite zone (50 km ~ 2) in the southern part of the ore-forming field has been carried out with a reserve of 200 million tons of pyrite , Cu, sn high grade. This is the largest deposit in Europe. The associated components are Pb, Zn, As, Sb, Bi, In, Ca, Co, Se, Ag and Au. The burial depth of the orebodies is> 200m. Geochemical measurements . The application of all geochemical methods has proved to be very effective.
