| 摘 要： | 波密深成岩体是早侏罗世冈瓦纳古陆北缘—陆缘弧型大陆边缘演化阶段弧盆构造格局中 ,于弧—陆聚敛体制下的一次I型花岗岩构造侵入事件。其不同岩石类型为同源岩浆多次脉动上侵的结果 ,岩浆活动构造环境早期为岛弧建造 ,晚期为弧陆聚敛。

| Abstract: | Bomi plutonic rocks is a tectonic instrusive event that happened in early Jurassic Epoch on the north active margin of the Gondwana where was under the process of the Gondwana margin arc. Its series of rocks are inferred as the result that the same consanguineous magma instrusy in the form of multiple pulsation. Its originated tectonic surroundings can be inferred as arc construction early and arc continent collosion latest. |
