Abstract
Bauxite has been discovered since 1940's in Guizhou, and the emphasis of the study have been placed on the generation age of bauxite -bearing rock series. In this paper, a lithographic description of central Guizhou -northern Guizhou -southern Chongqing area was given on the basis of nine standard sections of bauxite-bearing rock series, and a detailed statistic analysis was made for sporo-pollen genera and species widely distributed in Carboniferous Jiujialu Formation and Dazhuyuan Formation and middle Permian Liangshan Formation. Based on data available and related geological characteristics, the authors hold that the age of Jiujialu Formation in Qingzhen and Xiuwen of central Guizhou to Zunyi area and their vicinities belongs to early -middle Datang period of early Carboniferous, and Dazhuyuan Formation in northern Guizhou -southern Chongqing area should be early Maping period of late Carboniferous.关键词
