Abstract

Based on an interpretation of linear and ring structures and the extraction of alteration information

from TM imagines, in combination with ore deposit geology and geochemical data, the authors formulated a linear-

ring structure model for ore deposit location in the Laochang ore zone according to the theory of remote sensing

deposit geology. Under the background of the regional NNW-trending tectonic belt, the cross overlapping ringed

structure is formed by the superimposition of the NS-trending axial Nanlao ring reflecting the Hercynian volcanic

depression and a series of EW-trending axial lenticular structures reflecting the Yanshanian-Himalayan concealed

intermediate-acid rock bodies. The anomalous hue zones controlled by NNW-striking lines show the alteration

information. The overlapping segments are places favorable for mineralization.
