The Survey of Vortex Structure in Jiaodong Area with Landsat-5 TM Data
胶东地区旋扭构造的遥感探测

The vortex structures were observed in the west of Jiaodong area,Shan-dong Province on the Landsat image. The vortex structure consist of a nuclear co-lumn,a group of vortical surfaces and rock slices between the vortical surface.The mathematical model of the vortex structure was established.The stress analysiswas made. The relationship between the gold ore deposits and the vortex structureswas established.The research indicates that the good ore deposits is always locatedin the vortex structures.The gold ore deposit formed by hydrothermal alterationand replacement of faulting tectonoclastic rocks are almost located in the vorticalsurfaces between the rock slices.The gold ore deposits formed by hydrothermal al-teration and fill of fissures of rock slices are almost located in the tension joints(faults)and the fold of the rock slices.
