摘　　要：层控矽卡岩矿床是铜陵乃至长江中下游地区重要的矿床类型。相对于区域和矿田尺度,矿床、矿体级次的构造对矿质局部富集的控制作用研究较薄弱。本文在前人研究基础上,以冬瓜山C_(2)-P_(1)层间构造带矿体为代表,开展了大比例尺构造精细解剖,分析了层间构造带中次级构造的控矿特征,梳理了研究区的构造体系成生规律,总结了构造控矿模式和找矿标志,为铜陵以及长江中下游地区同类型矿床的找矿增储提供了依据。The strata-bound skarn deposit is an important deposit type in Tongling and even in the areas along the middle-lower reaches of the Yangtze River.Compared with the structures of regional or ore-field scales,those of a deposit or ore-body scale have been less studied for their control on the local ore enrichment.On the basis of previous studies,and focusing on the C_(2)-P_(1) strata-bound ore bodies of the Dongguashan copper deposit,this paper makes a refined large-scale analysis of the structures,discusses ore-controlling characteristics of secondary structures in the interlayer tectonic zone,probes into the formation law of the tectonic system,and gives a summary of the tectonic ore-controlling model and prospecting signs in the study area,providing a theoretical basis for prospecting same deposits in Tongling and beyond.
