这一类矿床矿化受层间氧化后生分带的控制,以前一直认为这类矿化是同生作用造成,勘探实践证明,最有效的找矿依据是层间氧化带的存在,而不是有利的岩相,矿体则位于带的尖灭部位。目前已知这类矿床分布在许多地方,如美国怀俄明盆地以及达科塔西 The mineralization of this type of deposit is controlled by the zonation of strata after interlayer oxidation. Previously, such mineralization was thought to be caused by syngenetic effects. Exploration proved that the most effective prospecting is based on the existence of an interlayer oxidation zone rather than an advantage Of the lithofacies, the ore body is located in the pinch out of the band site. It is known that such deposits are distributed in many places, such as the Wyoming Basin in the United States and Dakota
