暂时性片流沿着一定坡面或溪沟,将近源的碎屑物质搬运到岩溶洼地所形成的堆积物,我们称为填积相沉积。过去,许多著作对冲积环境中的河流沉积,冲积扇沉积作过精辟地论述,而岩溶地区的这类山间片状流水所形成的沉积物,还很少研究或报道。近年我队新生代地质小组在开展草海盆地演化的研究工作中,发现了这一类型沉积物,它具有自身的一系列特征,了解这些特征,将为研究喀斯特地区的古地理、古环境,以及古砂矿的探寻,是很有必要的。本文拟以草海盆地晚上新世五里岗组为例,着重论述填积相的分布特点、沉积特征和形成条件。谬误之处,敬请指正。
Temporary flow along a certain slope or creek ditch, near the source of debris material transported to the karst depressions formed by the accumulation of sediment, we call the facies sediment deposition. In the past, many works have dealt with river sedimentary and alluvial fan deposition in alluvial environments in an exaggerated manner. However, sediments formed by such plateau flowing water in karst areas are rarely studied or reported. In recent years, our team of Cenozoic geological team in the study of the evolution of the Caohai Basin, discovered this type of sediment, it has its own series of features, understanding of these features, will study the karst paleogeography, ancient environment, As well as the exploration of ancient sand, it is necessary. Taking Woligang formation in the Late Pleistocene in Caohai Basin as an example, this paper focuses on the distribution characteristics of sedimentary facies, sedimentary characteristics and formation conditions. Fallacy, please correct me.
