摘　　要：构造对楚雄盆地砂岩铜矿床的控制主要表现在三个层次:盆地构造演化控制了中生代到新生代沉积建造的发育,形成与矿化密切相关的三色建造,同时控制了盆地的古地理格局。基底断层和同生断层控制区内矿带的分布,矿区内的断裂构造和褶皱构造直接控制了矿体的形态和产状。There are three types of structures c ontrol on the sandstone-type copper deposits in the Chuxiong basin.That is,the evolution of basin structure controls the formation o f the Mesozoic-Cenozoic sedimentary formation,which consists of three-colors sediment formations in relation to minerallization,simultaneo usly controls the style of palaeogeograp hy.Basement faults and growth fault s control the distribution of minera l-ization belt in this district.The fa ults and folds in mine area control th e shape and orientation of the ore-bodies.
