摘　　要：运用套合地球化学模式谱系和成矿可利用元素的理论,利用中条山区1∶5万区域化探资料,对成矿带内化探原始数据分绛县群和中条群进行了分区处理,重新圈定了异常。将大于异常下限的那部分金属量作为成矿可利用金属量,用异常内探明的资源储量与预测资源量之比作为可成矿金属量,计算出了成矿带内可成矿金属量为32%,预测了总资源量和潜在的资源量。通过分析异常特征和成矿地质条件以及资源量预测情况,提出了铜矿峪矿区外围和北峪短轴背斜一带仍是今后找矿的主要地区。Using the geochemical pattern lineage and the theory of usable elements for mineralization, the authors, based on 1：50000 regional geochemical data of Zhongtiaoshan area, have made divisional processing of the original data from the ore - forming belt in accord with Jiangxian Group and Zhongtiao Group, and re - delineate the anomalies. The part of metal quantity higher than the threshold was regarded as the usable metal quantity for mineralization, and the ratio of the proved resource reserves to the prognostic resource quantity in the anomaly was regarded as the metal quantity suitable for mineralization. Calculation shows that the metal quantity suitable for mineralization is 32%. The total resource quantity and the potential resource quantity were also predicted. On the basis of anomaly characteristics, metallogenie geological conditions and resource quantity prognosis, the authors hold that the outskirts of the Tongkuangyu ore district and the areas around Beiyu braehyantieline are major places for further ore - prospecting work.
