黔北务正道地区及邻区石炭纪—二叠纪之交海平面变化对铝土矿的控制
Control of Sea-level Changes over the Forming of Bauxite between Carboniferous and Permian in Northern Guizhou and Adjacent Regions
摘要
Abstract
Sea-level fluctuated frequently in South China during the late Carboniferous to early Permian, which was constrained by the glaciations. The stage of Dalaun stage to Xiaodushanian stage witnessed the maximum sea transgression, during which the carbonate widely developed. The maximum regression during Zisongian stage to Longlinian stage resulted in the thinning carbonate sedimentary. What's more, weathering denudation occurs especially in the northern Guizhou Province. This long time of depositional hiatus is propitious to the forming of the bauxite. On the basis of the data of sea-level changes in South China, paleogeographic changes and paleoclimate, it is inferred that the forming age of bauxite distributing in northern Guizhou is from Zisongian stage to Longlinian stage, during which the South China experienced the maximum regression.关键词
