滇中及邻区前地台大地构造演化与铜成矿作用

通过构造层的划分，探讨滇中及邻区前边台演化与运动特征。认为该地区前地台经历了萌陆壳稳定阶段、原陆壳活动阶段、稳定阶段和地槽阶段。壳体演化与运动是幔交替活动与壳体成熟之间互相联系互相制约的结果。最后总结了钢成矿作用与构造演化的若干关系。

ON THE TECTONICS AND COPPER METALLOGENY OF THE PREPLATFORM IN CENTRAL YUNNAN AND ITS NEIBORING DISTRICT

On the basis of structural stage division, evolutional and movement characteristics of preplatform in central Yunnan and its neiboring district are studied in this paper. It is thought that the crustobody went through protocontinental mobile, stable, and geosynclinal stages and its evolutiOn and movement become of both relation and condition each other between alternative mantle activity and crustobody maturation. Finally, this paper sums up several kind of relations between copper metallogeny and tectonic evolution.
