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

除了结晶分外,富氟花岗液态不混溶作用也是晶成成矿的重要机制。

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

矿床类型以期分交代型、气成热液型、晶型、风化壳型和砂矿型为主。
