镇旬盆地南缘志留系金多金属矿成矿地质条件分析及找矿远景

GEOLOGIC CONDITION AND PROSPECTIVE POTENTIAL OF GOLD-POLYMETALLIC MINERALIZATION IN DEVONIAN SYSTEM AT THE SOUTH MARGIN OF THE ZHEN'AN-XUNYANG BASIN

镇(安)旬(阳)沉积盆地南缘志留系中分布着丰富的金、铅锌、铜等矿产资源。近年来,在盆地南缘的旬阳—白河一带的志留系中新发现了多处金、铜矿床(点),使本区金、铜地质找矿取得了重要进展。经对金、铅锌、铜矿成矿条件对比分析,认为镇旬盆地南缘志留系金多金属矿主要受地层和构造的双重控制。该区金、铅锌、铜矿资源潜力巨大,随着矿产资源的勘查,有望取得地质找矿的重大突破。

Gold, lead, zinc and copper mineral resources are abundant in the Devonian system at the south margin of the Zhen＇ an-Xunyang sedimentary basin. Discoveries of a lot of gold and cop- per occurrences in the Devonian system in Xunyang-Baihe district at the south margin of the basin have promoted the progress of ore-prospecting in this area. Analysis and comparison of metaUogenic conditions indicated that mineralization of gold polymetallic minerals occurring in the Devonian system are confined by stratigraphy and structure. This area has a great potential for prospecting gold, lead, zinc and copper mineral resources. It would be very prospective in breaking through at ore finding with further exploration of mineral resources in this area.
