摘要

Till now, Central Southern section of Lancang River in Yunnan has been founded with copper 34 points of multi-metallic ore deposit, sediment gritstone model-sediment reformed model-middle/low-temperature hydrothermal model- volcano(sediment)hydrothermal model forming into deposit formation pedigree; original third pedigree namely as chalky, Jurassic- Trias- Permian- Cambrian-Middle Proterozoic formed into mineralization date pedigree; most of copper multi-metallie deposits are spread within Simao-Longdong river Late Paleozoic-Trias basin, especially combined belt of Simao-Lincanghu basin between Lancang River and Jiufang zone of fracture, which forms into spacious pedigree along Lancang River valley and edge.Abnormal mineral geology and identification for mineral exploitation include deep and large rupture belt and its adjacency becoming beneficial location to seek for copper ore associated with magma invasion and break-forth activity, and location for rupture cultivation in Simao Aoxian which is always beneficial location to seek for hydrothermal(impulse)modeled copper mine; Moreover, red stratum occurring in Mesozoic and Cenozoic especially Jurassic and cretaceous scrappy stratum become abnormal sign for copper mineral geology about sedimentation-reforming type; stratum at late/middle Triassic lava become sign for seeking for copper ore associated with volcanic activity. Currently, alkaline element Na, Ca, Mg and K benefit for determination of copper mineralization belt, microelement combination is Sb, Au, As, Cu, Pb, Zn, Be, Sr, Sn etc; Aeromagnetic△Z includes quantitative polarization, vertical single derivative, filtration and other relevant abnormities; Gravity depends upon density grads field, vertical single derivative and gravity residual abnormity, which benefits for seeking for copper multi-metallic deposit at local area.
