metasomatic

1·Described for the first time in this paper the hackly microcline, aa typomorphic mineral in potash metasomatic uranium deposits.

本文首次系统总结了钾交代型铀矿床的标型矿物——犬牙状微斜长石的五项标型特征。

2·There exists much controversy concerning the genesis of myrmekite, and most geologists hold that myrmekite is of metasomatic origin.

关于蠕状石的成因，许多地质学家提出各种不同的成因假说，多数人认为是交代生成的。

3·More granitic rocks are produced in the late-stage of metasomatism, which could be remelt, and each successive melt could be solidified and modified by metasomatic fluids.

在交代作用后期，更多的花岗岩形成，这些花岗岩可再熔化，熔化后又会凝固并被交代流体作用。

4·From the above, it is evident that the Langshan granite is an in-situ metasomatic granite, which has not undergone the phase of melting magma.

上述特征反映了狼山花岗岩是未经熔融岩浆阶段改造的原地交代成因花岗岩。

5·No distinguished difference can be found between magmatic skarn and contact metasomatic skarn in mineral assemblages and chemical composition.

其矿物组成、化学成分与接触交代夕卡岩无明显差别。
