摘　　要：从地质与物探角度,论证川滇黔菱形地块可以构成扬子准地台西南缘一个Ⅱ级构造单元,范围较原"康滇地轴"稍有扩大。菱形地块四周由4条边界断裂围限,致使地表与深部的构造形迹呈现良好的对应关系。古元古代末期构造运动导致菱形地块分裂解体,形成3个次级构造单元,从此开创各自不同的地质发展史。简要阐述菱形地块地质构造演化及成矿作用特征。According to the geological and geophysical characteristics, we prove that the Chuan-Dian-Qian rhombic massif is a Ⅱ-order tectonic unit in the southwest margin of Yangzi paraplatform. This rhombic massif is enveloped by 4 boundary faults. In the late stage of Palaeoproterozoic, it was divided into 3 suborder units by tectonic movement, which had different geological development history then. In this paper, we briefly describe the characteristics of its geological tectonic evolution and metallogenesis.
