伟晶岩

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

除了结晶分异模式外,富氟花岗浆液态不混溶作用也是伟晶矿的重要机制。

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

矿床类以浆期分异交代、气热液、伟晶、化壳和砂矿为主。
