甘肃北山老君庙北金矿土壤地球化学特征及找矿前景
Geochemical characteristics of soils and prospecting potential of the northern Laojunmiao gold deposit in the Beishan area,Gansu Province
摘要
Abstract
Thenorthern Laojunmiao gold deposit is located in the southern zone of the Beishan area,Gansu Province,and on the north-eastern margin of the Tarim block.It resides in a tectonic environment of the Yaodongliang-Xiaoxigong Paleoproterozoic rift basin.This study delineated five comprehensive anomaly zones in the area through a 1:10,000 geochemical soil survey.As verified by trenching exploration,three gold ore bodies,one gold-silver ore body,and two low-grade gold ore bodies were identified in the comprehensive a-nomaly zones,suggesting satisfactory prospecting results.Based on the comprehensive geological and geochemical anomaly characteris-tics of the deposit,this study established an integrated geological-geochemical prospecting model centering on the HT1 comprehensive anomaly zone.Moreover,it proposed the subsequent prospecting direction,providing a significant reference for the deep and peripheral prospecting in the area.关键词
