许多找矿实例表明,对矿体上方岩石中的金属含量进行简单的全分析,并不能发现所存在的异常。只有分析元素的某些活动形式,才能探测出与这种矿床有关的异常。尽管对金属通过厚的沉积盖层的迁移机理尚未完全了解,
Many prospecting examples show that a simple and complete analysis of the metal content of the rock above the ore body does not reveal any anomalies that are present. Only by analyzing some forms of activity of elements can we detect anomalies associated with this deposit. Although the mechanism of migration of metals through a thick caprock has not yet been fully understood,
