Abstract
Analysis of characteristics of the rocks of Carboniferous strata unit, the structure of sedimentary features and sequence shows that Carboniferous strata developed well and sequence continuously in Helan Mountains area, and litbostratigraphic sequences from bottom to up can be divided into the Tupo Fm and the Taiyuan Fm. The rock association mainly consists of terrigenous clastic rock, argillaceous rock and carbonate rock sedimentary. As to the rock characteristics, stratigraphic sequence, facies and environment evolution characteristics, Helan Mountains area of carboniferous sedimentary evolution of the sequence is a retreat-type shallow water delta sedimentary sequence in the genera]. In the late carboniferous to the early Permian, constituent style of deposition has changed significantly in the delta system, it shows a rule that there is strong wave action in early stage, tidal effects become obvious in middle stage, and fluvial sedimentary evolution increases rapidly in late stage.关键词
