pegmatite

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

除了分异式外,富氟花岗岩浆液态不混溶作用也是伟岩成岩成矿的重要机制。

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

矿床类以岩浆晚期分异交代、气成热液、伟岩、风化砂矿为主。
