在地壳的地球化学场内,金属矿床是强烈而密集的异常,常常具有某种程度的同心带状组构和相当清晰的梯度界限。上述异常的规模可以极不一样,但是,在多数情况下,它们不会超过10~8—10~9米~3,这就造就了它们是局限的和密集的概念。解决这类异常特征强度的问题较复杂。与具有元素较均匀分布的岩体和岩 In the geochemical field of the crust, metal deposits are intense and dense anomalies, often with some degree of concentric banded structure and fairly sharp gradient boundaries. The size of the anomalies can be quite different, but in most cases they do not exceed 10-8-10-9 m, which creates a concept that they are both localized and dense. The problem of solving the strength of such abnormal features is complicated. With more evenly distributed elements and rock mass
