摘　　要：“钦州残余地槽”一直被认为是东吴运动褶皱回返的，本文通过沉积相古地理、古生物特征及地质构造特征的分析对比，提出钦州残余地槽在早泥盆世中晚期封闭。Qinzhou residual geosyncline” has been considered to be formed by folding inversion in Dongwu Revolution. By analysis and correlation of sedimentary facies, palaeogeography, palaeontology and geological structures, the author puts forward that Qinzhou residual geosyncline was closed in the middle and late Early Devonian, but still belongs to the scope of Caledonian folding system in South China.
