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,富氟浆液态不混溶作用也是晶成成的重要机。

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

类型以浆晚期分异交代型、气成热液型、晶型、风化壳型和砂型为主。
