A tectno-magmatic province in relationship with the Dalimu and Sino-Korean paraplatforms defines two giant hyperalkaline to alkaline to carbonate mineralization belts.

塔里木一中朝两个准地台相关构造-岩浆带中,有两个巨大的超基性-碱性-碳酸岩杂岩磷矿成矿带。

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

成矿物质源于碱性玄武岩浆，基性次火山岩浆多次脉动式入侵是矿床形成的必要条件。

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

矿床类以岩浆晚期分异、气成热液、伟晶岩、风化壳和砂矿为主。

It is inferred from the thermometry of geyserite and adarce inclusions that underground temperatures for the hot spring system in Tengchong are .
