摘要
洪水河地区位于东昆中新元古代—早古生代缝合带(KZS)和东昆中岩浆弧带(Pt_3-J),区内早二叠世花岗闪长岩与多期次不同性质的断裂构造具备热液型金矿成矿地质条件。近年来通过首次开展1∶2.5万地球化学测量工作,在该区圈定了以Au、As、Bi、W、Pb为元素组合的综合异常,地球化学测量异常明显,元素相关性好,通过对该异常进行验证,发现了较好的找矿线索。地球化学异常中心及北东向构造破碎带具有较大的找矿潜力。
Hongshuihekou area is located in Dongkunlun neoproterozoic in early Paleozoic suture zone（ KZS） and the east（ the Pt3-J） of magma arc in the belt. In early Permian granodiorite with many different properties of fracture structure,It issues itself with ore-forming geological conditions of the hydrothermal deposits. In recent years through 1∶ 25 000 geochemical survey work,for the first time in the area,it delineated Au,Pb,As,Bi,W,etc. as elements in combination of comprehensive anomaly. Geochemical anomaly and elements correlation are validated by the exception to show a good prospecting clues. Geochemical anomaly center and northern east to tectonic fracture zone will have great prospecting potential.
