广县造山运动作为华南地质学的一个重要概念，诞生于70年前。一般认为它是志留纪末华夏地块和扬子地块会聚引起的一次造山运动。根据广西及邻区地质研究的最新进展，桂西及桂中的柳州-合山地区可能属于早古生代稳定地块。广县造山运动起源于寒武纪末云开地块向北平移，并在两地块之间形成大明山-大瑶山褶皱带。这可能与泛非晚期造山运动有关。晚奥陶世-早志留世是华夏地块与扬子地块汇聚的时期，主要影响到湘赣两省。志留纪末本区没有发生过造山运动。
The Guangxian Orogeny, as an important concept on geology of South China, was created 70 years ago. It is generally regarded as an orogenic movement caused by the convergence of the Cathaysian and Yangtze blocks at the end of Silurian. Based on the recent progress of the geological research on Guangxi and adjacent areas, western Guangxi and Liuzhou-Heshan area of central Guangxi may belong to a stable block of Early Paleozoic. The Guangxian Orogeny originated from the northward translation of the Yunkai Block on its south at the end of Cambrian, and formed the Damingshan-Dayaoshan fold belt between the two blocks. It was possibly related with the Late Pan-African Orogeny. The convergence of the Cathaysian and Yangtze blocks occurred in Late Ordovician to Early Silurian and mainly had effect on Hunan and Jiangxi provinces. The term “Chongyu Orogeny” may be suitable for it. At the end of Silurian orogenic movement did not occur in this area.
