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 district. - 南北轴向的南老环和东西轴向的透镜体系列分别反映了华力西期火山洼地和燕山期－喜马拉雅期隐伏中酸性岩体，两者叠加形成老厂环－环横叠式结构，与隐伏岩体同期或稍后的NW向、NE向共扼线性构造带与环形构造叠加交切，多组构造的交汇点是有利的成矿部位。
The NS axial Nanlao ring and the EW axial lenses series reflect the Variscan volcanic depressions and the Yanshanian-Himalayan concealed intermediate-acid intrusive bodies respectively, and their superimposition has formed Laochang ring-ring transverse overlapping style structure; the NW-trending and NE-trending conjugate structure belts formed contemporaneous with or a bit later than the concealed intrusive bodies have overlapped and dissected ring structures, and the intersections of various structures are places favorable for mineralization.
