通过以随机取样为总体对地质体中元素分布型式的研究,认为元素在地质体中并不总是呈正态或对数正态分布,常可表现出比较复杂的型式,即呈多重母体分布。研究认为:多重母体往往代表了复杂地质作用过程的迭加。在岩浆一热液作用过程中,元素的分布受岩浆演化阶段和相应物理化学环境的影响而表现不同分布型式。研究表明:单一母体分布可以表示一次或多次相似条件下地质作用的产物;多次差异显著的地质作用结果往往表现为二重或多重复合母体分布;不同地质作用物理化学条件差异显著程度,表现为母体分离度的大小。因此,可以利用岩体中元素的分布型式和母体分离度来研究岩体的演化或成矿热液作用迭加过程中微量元素的集中、分散趋势。一般情况下,对推断岩体的成矿作用是很有意义的。上述规律已在豫西花岗岩体含矿性评价中得到应用。
Through random sampling as a general study of the distribution patterns of elements in geologic bodies, it is considered that the elements are not always normal or logarithmic normal distributions in geological bodies, and can often exhibit more complex patterns, ie, multiple maternal distributions . Research suggests that multiple matrices often represent a superposition of complex geological processes. During the magmatic-hydrothermal process, the distribution of elements shows different distribution patterns under the influence of magmatic evolution stage and corresponding physicochemical environment. The results show that the single matrix distribution can represent one or more geological products under similar conditions. The geological results with multiple differences are often characterized by two or more complex matrix distributions. The differences of physicochemical conditions of different geological processes are significant, For the size of the parental resolution. Therefore, the distribution pattern of the elements in the rock mass and the degree of parental dissociation can be used to study the trend of the concentration and dispersion of trace elements in the process of rock mass evolution or superposition of the hydrothermal fluid. In general, it makes sense to infer the mineralization of the rock mass. The above rules have been applied in the evaluation of the granite plutons in western Henan Province.
