摘要
以１∶５万区调资料为主对桂东桂平地区寒武系沉积特征进行描述，根据岩石学、沉积学特征与岩相组合，指出该区以浊流沉积为主。对其中具牵引流沉积特征的夹层一部分与浊流后期转化而成的牵引流有关，一部分是受斜坡导向作用限制的大洋底流。根据浊流滑动方向指出碎屑来源于广西南面的云开古岛弧。
Mainly based on the regional geological surveying data on the scale of 1:50000, this paper described the sedimentary characteristics of Cambrian system in Guiping region. According to lithological and sedimentary characteristics and lithofacies association, the author points out that in this region the majority of sediment is turbidite, in which, part of the interlayers with the sedimentary characteristics of traction current is relative to the traction current transforming from later-stage tubidity current, and the rest is relative to the ocean bottom current limited by slope's directivity. In line with the sliding direction of turbidity current, the author indicates in which the clast originated from the island arc of Yunkai oldland.
