在研究金属矿床时,区分组成相似而成因不同的岩石经常会遇到困难。尤其难以区分矿物成分相似的矽卡岩与类矽卡岩,以及在高温热液作用下形成的大理岩与接触变质产生的大理岩。 既然铀是成岩和成矿作用最灵敏的指示剂,为了鉴定,在地质研究中采用碎片放射性照像法日益增多。用这种方法在薄片上测定分散铀的含量,并查明它的空间分布情
In studying metal deposits, it is often difficult to distinguish between rocks of similar composition and different origins. In particular, it is difficult to distinguish between skarn and skarn with similar mineral composition, as well as marble and metamorphic marble produced under the action of hydrothermal fluids. Since uranium is the most sensitive indicator of diagenesis and metallogenesis, the use of fragmented radiographic methods in geological research is increasing for the purpose of identification. This method was used to determine the amount of dispersed uranium in the sheet and to ascertain its spatial distribution
