摘要
老湾金矿带是桐柏—大别山地区重要的构造蚀变岩型金成矿带，在对矿带成矿地质背景、地球物理、地球化学特征分析研究的基础上，建立找矿模型及找矿标志，以期望以模型指导找矿，提高矿床研究水平和地质找矿效果。通过建立模型及综合找矿评价标志，对矿床认识程度有了进一步提高，取得了较好的找矿效果。
Laowan gold ore belt is a primary gold mineralization belt of the tectonic altered rock type in the Tongbai-Dabie region.On the basis of analysis and study of ore-forming geological settings,geophysical and geochemical features of the ore belt,the authors have established the prospecting pattern and criteria,for the purpose of guiding ore prospecting and raising the research level and ore prospecting effect of the zone.By way of the work of establishing prospecting pattern and evaluating criteria of overall prospecting,the desired results have been achieved.
