凤-太矿田大型铅锌矿床勘查靶区及其找矿思路
Exploration target area for large-scale lead and zinc deposit and its prospecting thoughts in Fengxian-Taibai ore field, Shaanxi
【摘要】 在综合分析凤-太矿田已知铅锌矿床成矿特征及控矿因素的基础上,结合近年来在本区进行隐伏矿找矿的勘查实践,提出秦家梁地段和古字梁地段为两处最有潜力的隐伏矿找矿靶区。其中,秦家梁靶区具备寻找受次级断陷盆地控制的热水沉积型矿床的成矿条件,通过1∶1万岩相-构造填图、TEM物探方法定位及直孔钻探验证等可望直接发现隐伏的铅锌矿体。古字梁地区具有与甘肃厂坝铅锌矿床十分相似的成矿地质构造背景,应进一步开展大比例尺地质填图以缩小找矿验证地段。
【Abstract】 On the basis of comprehensive analyzing metallogenic geological condition of explored mineral deposits in Fengxian-Taibai lead and zinc ore filed, it is considered that Qinjialiang and Guziliang two exploration target regions are very prospective to find new large-scale lead and zinc deposits, combined with exploration practice. However, Qinjialiang region have favorable ore-forming condition to prospect hydrothermal sedimentary typed lead and zinc deposits controlled by localized fault basin, and could find new lead and zinc ore bodies in the target region by means of lithofacies-geology mapping in 1∶10000 scales and other survey work, and so on. But Guziliang region has the same mineralization geological structure setting as Xicheng ore field, and should make geology mapping in 1∶10000 scales to reduce region for prospecting and verifying.
