In terms of their geological and geochemical characteristics as well as the ages of these plutons , these three sub - belts from south to north are interpreted as syn - subductional , syn - collisional and post - collisional plutons respectively . composed of quartz diorite and quartz monzonite , the syn - subduction plutonic rocks are confined only to the south kunlun massif 俯沖期侵入巖僅出露于蛇綠巖帶之南的昆南地塊上,巖性組合為石英閃長巖-石英二長巖,三個主要巖體獲鋯石u - pb年齡值為481ma 、 461ma 、 452ma ,均為奧陶紀。

The lithologies of intrusive rocks were re - determined , for example , the rock previously named as diorite in southern area was renamed as gabbro , and the dike rock distributed along nnw as spessartite which was related to formation of the zhulazaga gold deposit to some extent 對礦區各類侵入巖重新厘定了它們的巖性特征,如礦區東南部原閃長巖重新確定為輝長巖,確定nnw向分布的脈巖為閃斜煌斑巖,且認為后者和朱拉扎嗄金礦的形成有一定的關系。

We usually don't care whether a rock is classified as a granodiorte or diorite or tonalite . 我們通常并不注意某種巖石是屬于花崗閃光巖、閃長巖還是英云閃長巖。

At flat the host is quartz diorite with a finegrained contact phase . 在富來梯,主巖為細粒接觸相的石英閃長巖。
