萤石是热液铀矿床的典型“伴生”矿物。它在与陆相火山作用有关的铀-钼矿床中分布最广。在这些矿床的侧翼,萤石经常形成脉体的主要部分。工业萤石矿化在每个矿区都富集在一定的标高内,并在许多情况下,到深部变成铀、钨、铜和多金属矿床。然而,利用萤石存在的事实,对于寻找和预测深部铀及其它矿化到目前为止还是困难的,因为在类似的地质环境和成矿阶段也能形成单一的热液萤石矿床。
Fluorite is a typical “associated” mineral in hydrothermal uranium deposits. It is the most widely distributed in uranium-molybdenum deposits associated with continental volcanism. Flanks of these deposits often form the major part of the veins. Industrial fluorite mineralization is enriched within certain elevations in each mine and in many cases deep into uranium, tungsten, copper and polymetallic deposits. However, the fact that fluorites exist makes it difficult to find and predict deep uranium and other mineralizations so far, as a single hydrothermal fluorite deposit can also be formed in similar geological settings and mineralization stages.
