熔离作用

在岩体的形态与岩石组构上，它们以岩席、岩筒和脉岩的形式出现，并发育有强烈的熔离作用与流动构造；

The rocks occur as sheet , pipe and vein with strong liquation and flow structure .

壳源组分的加入是促进岩浆熔离作用的重要因素。

The addition of the crustal materials into the magma played an important role in promoting the liquation processes .

岩浆的深部熔离作用使岩体的出露大小与矿床规模没有正相关性；

Because of its deep differentiation by liquation , the deposit scale isn 't positive correlation with the outlet size of rock-body ;

岩浆起源于上地幔，属于拉斑玄武岩系列，发生过金属硫化物的熔离作用。

The magma originated from the upper mantle and belongs to the tholeiitic series which has undergone immiscible separation of metal sulfide .

源自上地幔局部熔融的母岩浆，在通过上地幔岩石圈上升侵位过程中，就地发生硫化物熔离作用和硫化作用，形成早期的富镍矿体和部分贫矿石；

Parent magma which originated from partial melting of the upper mantle generated sulfide melting segregation and sulfurization to form early rich nickel ore bodies and some poor ore during rifting through the upper mantle lithosphere to emplace .

硫化铜镍工业富集需要相对稳定的构造环境，构造长期活动，使得含矿岩浆能够上侵到地壳浅部并发生良好的结晶重力分异作用和硫化物硅酸盐熔离作用，并进而富集成矿。

The industrial enrichment of Cu-Ni sulfide needs a relatively stable structure environment , and the long - time movement of structures makes ore magma invade into the shallow crust , gives rise to better crystallization , gravity differentiation and liquation of sulfides and silicates , and further forms ores .

花岗质岩浆的分异、熔离、自交代作用是该区锡多金属矿床成矿的主因。

The authors concluded that differentiation , liquation and self-metasomatism of granitic magma are main factors for tin-polymetallic mineralization in the area .
