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,富岩浆液态不混溶作用也是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.

型以岩浆晚期分异交代型、气成热液型、晶岩型、风化壳型和砂型为主。
