摘要
首次确认区内金红石的主要矿化层位为毛集群左老庄组一段地层 ,主要矿化集中区位于南召云阳—方城清河间 30km地段 ,并在宽坪群中也发现了新的矿化层位和矿化类型。首次发现大型粗粒易选矿体 ,突破了前人“呆矿”的结论。预测区内 5 0m以浅范围内金红石资源总量大于 5 0 0 0万吨 ,为一世界级的超大金红石矿产地。
It is the first time that the authors pointed out the main mineralization stratum of rutile is in Maoji Group , Zuolaozhuang Formation. The mineralization centrates in a 30 kilometre zone in Nanzhao,Yunyang-Fangcheng, Qinghe area. And new mineralization stratum and mineralization type was found in Kuanping Group, too. It is also the first time that the large scale macrograined , easy beneficiating rutile ore was found and the result of 'useless ore' had been breached. The rutile total resources within the depth 50 metre is more than 50 000 000 t. It is a world-scale super-large rutile mineral field.
