摘要
该文对铜井、金场地区水系沉积物18种元素进行了研究,结合工作区成矿地质条件,共圈出8个综合异常。对综合异常进行查证,新发现多处多金属矿(化)点和矿化线索,其中9处金矿(化)点和矿化线索,验证水系沉积物地球化学测量在该区具有较好的找矿效果。在综合异常分析和查证的基础上,结合区域成矿地质条件、区内矿产地质特征,圈定出3处找矿远景区。分别为金场—铜井一带金、铜、铁、汞、银找矿远景区、金佛院铬、铜找矿远景区和青杨行—孔家湖一带铜、铅、锌找矿远景区,为该区下一步找矿工作指明了方向。
Geochemical characteristics of stream sediments in Tongjing and Jinchang areas,characteristics of anomalous element assemblage and regional metallogenic potential have been analyzed and inferred,and 18 elements in the working area have been studied in this paper.Eight comprehensive anomalies have been delineated in combination with metallogenic geological conditions in the working area.By checking comprehensive anomalies,many polymetallic ore(mineralization)points and mineralization clues have been found.As showed by 9 gold ore(mineralization)points and mineralization clues,geochemical survey of stream sediments has good prospecting effect in this area.On the basis of comprehensive anomaly analysis and verification,combining with regional metallogenic geological conditions and mineral geological characteristics,three prospecting areas have been delineated.They are gold,copper,iron,mercury and silver prospecting areas in Jinchang-Tongjing area,chromium and copper prospecting areas in Jinfoyuan and copper prospecting areas in Qingyang Xing-Kongjiahu area.It will point out the direction for the next prospecting work in this area.
