研究火成岩中钼及与其伴生的金属元素的分布得以查明,在岩浆作用发展过程中,在每个构造-岩浆旋回范围内,钼和铀聚集于晚期的酸性岩浆分异物中,铜则集中在早期的基性岩浆岩内.许多情况下,弱减性的晚期分异物中钼、铜、铀的含量增高.在岩浆演化过程中,可能由于沉积岩(如富含有机物和硫化物硫的页岩、粘土和生物灰岩)富含钼、铀和铜而使岩浆岩也富含这些元素.计算地壳中酸性、中性、基性和超基性岩钼、铀、铜的克拉克值,分别得出:钼-
Studying the distribution of molybdenum and its associated metal elements in igneous rocks was investigated. During the development of magmatism, molybdenum and uranium accumulate in the late acidic magmatic subdivides within each tectono-magmatic cycle and copper concentrates in In the early mafic magmatic rocks, the content of molybdenum, copper and uranium increased in weakly degraded late-stage dissociated matter in many cases, which may be due to sedimentary rocks (such as shale rich in organic matter and sulfide sulfur, Clay, and biogenic limestones) are also enriched in magmatic rocks by the enrichment of molybdenum, uranium and copper.Calculation of the acid, neutral, basic and ultrabasic rock molybdenum, uranium and copper in the crust, :molybdenum-
