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。
Bomi deep pluton is an I-type granite intrusive event under the arc-land convergence system in the arc basin tectonic framework in the northern margin of Gondwana continental margin-continental marginal continental margin of Early Jurassic. The different types of rocks are the result of multiple pulsations intrusion of the same magma. The magmatic activity tectonic setting was built by island arc in the early stage, and convergent in the later stage.
