pegmatite

Beside fractional crystallization model,liquid immiscibility of Fluorine-rich granite magma is an important mechanism to form pegmatite and pegmatite type deposit.

除了结晶分异式外,富氟花岗岩浆液态不混溶作用也是伟晶岩成岩成的重要机制。

The types of deposits basically are differential metasomatism in the later magma, pneumatolytic hydrothermal process, pegmatite process, residual deposits and placer deposits.

床类以岩浆晚期分异交代、气成热液、伟晶岩、风化壳和砂主。
