摘要: 西扬子大陆区泥盆系因有丰富的矿产资源一直为地学界所关注.在泥盆纪盆地演化中,地质事件与成矿关系极为密切.盆地沉积类型有台地型和海槽型两种.台地型泥盆系在沉积建造、生物群落、地质事件及沉积矿产等多方面均能与中、下扬子区相对比,故归属南方区扬子型泥盆系;海槽型泥盆系与台地型泥盆系在时空上均紧密衔接,但成矿作用有明显差别.海槽型泥盆系多产出层控型金和多金属矿床,台地型则以沉积矿床为主.

Abstract: There are abundant mineral resources in Devonian strata on the West Yangtze continent.Geological events during the Devonian basin evolution were very closely related to mineralization. There are two basin sediment types:the platform type and trough type.
