Pitchblende and chalcolite are much more radioactive than uranium itself.

沥清铀矿和铜铀云母比纯铀的放射性强得多。

The crystallization speed is variable with the changing of temperature and pH in the system.

沥青铀矿的结晶速度在不同的温度和pH条件下是不同的。

Studies of petrology and elemental geochemistry indicate that the Xiangshan uranium ore-field dacite porphyry belongs to intra-plate shoshonitic rock type and is a kind of shoshonitic dacite porphyry.

岩石学、元素地球化学研究表明，相山铀矿田的英安斑岩属于板内型钾玄质岩类，为钾玄质英安斑岩。

Radium does not occur free in nature but occurs in natural ores such as pitchblende as a disintegration product of radioactive decay of heavier elements, including uranium.

在自然界镭不存在游离状态，但存在于天然矿石中，如沥青铀矿，是更重元素放射性衰变的产物。
