康滇地轴位于扬子地台西部边缘,是我国著名的南北向构造带。在其北段广泛分布着不同时代、不同类型的花岗岩,沿安宁河深断裂和金河—箐河深断裂构成了南北向花岗岩带。这些花岗岩可分为两大类。一、陆壳重熔S型花岗岩,二、上地幔基性岩浆分异的Ⅰ型花岗岩。它们在时空分布、岩石化学性质、含矿性和成岩机理等方面都备具不同的
Kang Dian axis is located in the western edge of the Yangtze platform, is China’s famous north-south tectonic belt. There are widely distributed granites in different periods and different types in the northern section of the granite. The deep faults along the Anning River and the deep faults of the Jinhe-Tiehe River constitute the north-south granite belt. These granites can be divided into two broad categories. First, the continental crust remelted S-type granite, second, upper mantle sedimentary basic type Ⅰ granite. They have different spatiotemporal distribution, petrochemistry, ore-bearing and diagenetic mechanisms
