甘肃省肃北县二段井地区遥感地质特征及金多金属找矿预测

甘肃省肃北县二段井地区属于北山造山带南带拾金坡-金场沟金、铜、铁和铅锌、银、稀有金属成矿带,具有良好的成矿条件和找矿潜力。该文利用日本ALOS遥感数据,完成遥感地质解译工作,采用美国Landsat 8 OLI数据完成矿化蚀变信息的提取工作,并结合已有的地质矿产及物化探资料,对区内的成矿地质条件及找矿远景进行了分析预测,圈定了4处找矿远景预测区,可为后期野外地质找矿工作提供帮助。

Remote sensing geological characteristics and Au polymetallic mineralization prospecting prediction of the Erduanjing area in Subei County, Gansu Province

the Erduanjing area of Subei Mongol Autonomous County, Gansu Province, belongs to Jinchanggou gold, copper, iron, lead, zinc, silver and rare metals metallogenic belt of Shijinpo-Jinchanggou in the southern belt of Beishan Orogenic belt. In this paper, Alos remote sensing data from Japan are used to complete the geological interpretation of remote sensing, and the mineralization alteration information is extracted from the LANDSAT 8OLI data of the United States, based on the analysis and prediction of the ore-forming geological conditions and prospecting prospects in the area, four remote sensing prospecting areas have been delineated, which can be helpful to the field geological prospecting in the later stage.
