摘　　要：老湾金矿带是桐柏—大别山(北坡)金银成矿带的重要组成部分,老湾金矿床是该成矿带的主要矿床之一,同时也是我国重要的变质碎屑岩型大型金矿之一。在分析研究老湾金矿地质、地球物理、地球化学特征的基础上,建立综合找矿标志信息及找矿模型,以模型指导找矿和找矿靶区的定位分析,以期为该类型矿床的预测评价起到借鉴作用。The Laowan gold ore belt is an important component part of the Tongbai-Dabieshan （northern slope） gold-silver metallogenic belt, and the Laowan gold deposit is one of the major deposits in this belt and also one of the important large-size metamorphic clastic rock gold deposits in China. Based on an analysis of geological, geophysical and geochemical characteristics of the Laowan gold deposit, the authors established the integrated ore-prospecting criteria and ore-prospecting model to guide the ore exploration and target-locating work. The ore-prospecting criteria and ore-prospecting model are of great reference value in further work.
