The research on geochemical characteristics and isotopeage suggests that the deposit belongs to a magma-metasomatic pegmatite type deposit related to Fufang and Huitong granitic mass in genesis.
地球化学和同位素研究表明，该矿床为岩浆一交代花岗伟晶岩型矿床，成因上与付坊和会同岩体有关。

The dated isotope record shows that the fluctuations in global ice volume over the past several hundred thousand years have a pattern: an ice age occurs roughly once every 100,000 years.
同位素年代记录显示，过去几十万年全球冰量的波动有一个模式：冰河期大约每10万年发生一次。

In this case the geologists drilled into the stalagmites and estimated their age from the way that uranium decays into an isotope of thorium.
