继1976年原广西第八地质队凌云县深洞一带发现古裂隙中早二叠世的沉积灰岩“脉”后,广西区调四分队在南丹县六寨镇一带进行1:5万地质填图中,于丹池褶断带北段东侧发现分布于古裂隙中的沉积灰岩“脉”。它们充填于晚泥盆世和早—中石炭世灰岩中。见“脉”11条,在平面上多呈长条状、透镜状,剖面上呈囊状、脉状,且具右行雁列式排列特征。脉长5—49来,宽 Following the discovery of the “Permian” sedimentary limestone in the Early Cretaceous in the ancient cave of the eighth geological team in Guangxi Province in 1976, the Quaternary of Guangxi Region conducted a 1: 50000 geological survey in the vicinity of Liuzhai Town, Nandan County In the mapping, the “vein” of sedimentary limestone distributed in ancient fractures was found on the east side of the northern section of Danchi fold belt. They fill in the late Devonian and early - Middle Carboniferous limestone. See “pulse” 11, mostly in the plane strip, lenticular, section was cystic, veins, and the right line with the echelon arrangement features. 5-49 pulse length, wide
