中文摘要:海省祁漫塔格地区位于柴达木盆地西南缘,是青海东昆仑成矿带西部的重要组成部分。近10年来祁漫塔格地区完成20385km2的1:5万水系沉积物测量工作,实现了祁漫塔格地区1:5万水系沉积物测量工作的全面覆盖,提供了大批可供进一步开展工作的化探综合异常和找矿靶区,为祁漫塔格地区矿产资源评价工作提供了翔实的地球化学资料。经异常查证,区内已发现了夏日哈木、铜金山、拉陵高里河沟脑等多金属矿床及一批找矿信息,已证实具有小型-超大型规模,使祁漫塔格地区成为重要的矿产勘查地区。近年来祁漫塔格地区1:5万水系沉积物测量工作进展及找矿成果表明,1:5万水系沉积物测量工作在重要成矿带上对于矿床的发现具有重要作用,有力推动了祁漫塔格地区矿产资源调查评价工作的开展。

The techniques and application achievements in 1:50000 stream sediment survey of the Qimantage area, Qinghai Province
Abstract:The Qimantage area in Southwestern margin of the Qaidam Basin, is an important part of East Kunlun metallogenic belt in Qinghai Province. In the recent decade, an area of 20385 km2 of 1:50000 stream sediment survey was completed in the Qimantage area, which has achieved complete coverage of 1:50000 stream sediment survey in this area. It provides large quantities of geochemical anomalies and prospecting target areas for the further work, and also provides informative geochemical data for mineral resources evaluation in Qimantage. Through anomaly verification, the Xiarihamu, Tongjinshan amd Lalingaoli river polymetallic deposits have been discovered, which have been confirmed to have small-ultra large scale, making the Qimantage area become an important mineral exploration area. In recent years, the work process and prospecting results of 1:50000 stream sediment survey in Qimantage indicate that 1:50000 stream sediment survey is important for the discovery of ore deposits in important metallogenic belts, which has promoted investigation and evaluation of mineral resources in Qimantage.
