basaltic magma

The metallogenic material was from deep alkalic basaltic magma, and the pulsatory invasion was the necessary metallogenic condition of the ore deposit.

成矿物质源于碱性玄武岩浆，基性次火山岩浆多次脉动式入侵是矿床形成的必要条件。

The MA type is further divided into two subtypes of basaltic magma crystallization ( BMA) and ultramafic magma crystallization ( UMA).

MA型可分为玄武质岩浆结晶（BMA）亚类和超镁铁质岩浆结晶（UMA）亚类。

In North and Northeast China widely developed mantle-derived peridotite xenoliths, which were carried to the surface by alkali basaltic magma.

研究由玄武岩岩浆携带到地表的幔源橄榄岩包体可以获得上地幔的许多信息。

The parental magma is basaltic magma, and its content of MgO is a little high, the content of MgO is 9.42%.

母岩浆为是MgO含量较高的玄武质岩浆，MgO含量为9.42%。

Both fractional crystallization and partial melting are important processes that control the variation of chemical composition of basaltic magma.

分离结晶作用和部分熔融作用，是控制玄武岩浆化学成分变异的两种主要方式。

Basaltic magma is fluid.

玄武岩岩浆是流动的.

The alkalic basaltic magma of this stage may be derived from asthenosphere.

该阶段的碱性玄武岩浆可能来源于软流圈。
