magma

The metallogenic material was from deep alkalic basaltic magma, and the pulsatory invasion was the necessary metallogenic condition of the ore deposit.

矿物质源于碱性玄武，基性次火山多次脉动式入侵是矿床形的必要条件。

The magma of porphyritic moyite-monzogranite series in the middle stage mainly originated from the lower crust, being the product of collision-orogeny.

中期似斑状钾长花岗-二长花岗系列来源于下地壳，是碰撞造山作用的产物；

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,富氟花岗液态不混溶作用也是伟晶矿的重要机制。

Hence, for the minerals to be analyzed in some rocks, when there are all sorts of genesis with xenolith, magma, mantle and so on in them,the age of a certain single event can be respectively got.

因此，当某些体的被测矿物有捕虏体因、因、地幔因等各种来源时，可分别求出某单一事件的年龄。

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

矿床类型以晚期分异交代型、气热液型、伟晶型、风化壳型和砂矿型为主。
