摘　　要：基于安徽庐枞地区深部地质调查成果,探索了多源数据联合建模方法。以区域地质和成矿规律研究成果为基础,以深部探测最新认识为主线,综合地质、钻探、物探、遥感等多专业数据,联合构建庐枞盆地2 km以浅三维地质结构模型,实现了盆地结构、基底隆起、岩浆岩分布等三维地质结构的“透明化”表达。此外,构建了区内多个典型矿床模型,并对区域地质模型与典型矿床模型进行耦合验证,为庐枞地区三维成矿预测提供依据。This work explored a joint modeling method of multi-source data based on the results of deep geological survey in the Luzong area of Anhui Province.According to available regional geology and metallogenic regularity,this work constructed a 2 km three-dimensional shallow 3D geological structure model of the Luzong Basin,taking the latest knowledge of deep exploration as the main line,and combining with geological,drilling,geophysical and remote sensing data.This has realized the″transparent″expression of three-dimensional geological structure such as basin structure,basement uplift and magmatic rock distribution.In addition,several typical ore deposit models were constructed,and the coupling validation of the regional geological model and the typical ore deposit models was carried out to provide a basis for three-dimensional metallogenic prediction in the Luzong area.
