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,富氟花岗浆液态不混溶作用也是伟晶矿重要机制。

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

矿床类型以浆晚期分异交代型、气热液型、伟晶型、风化壳型和砂矿型为主。
