四川红卓铜矿是一个新发现的矿点,研究程度比较低.通过野外地质工作及室内综合分析,重新划定了矿区地层顺序,认为矿区构造为脆韧性和脆性2个层次.脆韧性变形以顺层剪切为特征,构造序列可确定为脆韧性顺层剪切→褶皱、逆冲断层→断层正滑.红卓铜矿在成矿特点上受构造影响明显,断层将矿区分为南西、中央、北东3个带,以中央带岩浆成矿作用显示最强.

Hongzhuo copper deposit is a newly discovered mineralized point in Sichuan Province, it is in low research degree. Based on the field geological work and indoor comprehensive analysis, the stratigraphic sequence is re-established in mining area, and it is considered that there are two layers in ore area structure: ductile structure and ductile-brittle structure. Characteristic of ductile-brittle structure is shearing along layer. The structural sequence is ductile-brittle bedding shear to fold, thrust fault to normal fault. The mineralization of Hongzhuo copper deposit is obviously controlled by structure. The mining area was divided into three belts by faults: southwest, northeast and center belts, and center belt shows the strongest magmatic metallogenesis.
