| 摘 要： | 为了在八家子铅一锌一银矿田寻找新的矿种——钼矿，通过对八家子一杨家杖子成矿带上矿床特征的对比研究，认为此成矿带上每隔10km就出现一个矿集区，每个矿集区由数个或数十个矿床构成；在同一个矿集区中，围绕岩体这个成矿中心，金属矿化和成矿元素出现明显分带性。而八家子铅-锌-银矿床具有此类似特征。因此，提出八家子矿田存在一个完整的成矿分带系列，其成矿中心是炉沟的花岗斑岩体，岩体具备了寻找兰家沟式大型斑岩钼矿床的各种地质条件。此后，经对物化探异常的验证，发现八家子铅-锌-银多金属矿田的Mo异常内存在厚大钼矿体。

| Abstract: | In order to search new type of the molybdenum deposit in the Bajiazi lead-zinc-silver ore field, a comparison research has been carried out on the basis of deposit characteristics of Bajiazi-yangjiazhangzi ore zone. It is considered that there is an ores accumulation area every 10km, which is composed of several to tens of deposits; and the mineralization and ore elements show clear zonings around magmatite body every certain ore accumulation area.The Bajiazi lead-zinc-silver deposit bears similar feature. It is therefore proposed that there is a complete ore forming series in the Bajiazi ore field with the Lugou granite porphyry as a ore forming center which possess various geological conditions for the Lanjiagou type large scale porphyry molybdenum deposit. Thick molybdenum orebodies were found in Mo anomalies of the Bajiazi lead-zinc-silver polymetallic ore field. |
