| 摘 要： | 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

The Types of Granite Magma and Their Ore-Bearing Characteristics in The Northern Part of "Kang-Dian Axis" |
| |
| Abstract: | The northern part of "Kang-Dian Axis" is situated in the western margin
of the Yangzi platform. Here are distributed S type granite of the Jinning-
Chengjiang period and I type granite of the Lndosinian-Yenshan period. The S
type granite is located within the Yangzi platform. It associated closely with
rhyolite and is related to tine and tungstun ores. The I type granite occurs in
the transitional belt of the trough and stage. It is associated with the gabbro,
Emei mount basalt and syenite, and is related to the deposit of rare-earth,
niobium and tantalum. |
