Sedimentary facies of the Lower Carboniferous Nanmingshui Formation in Fuyun County, Xinjiang and their paleogeography signification
新疆富蕴县下石炭统南明水组沉积相及其古地理意义

Fan delta-, littoral-and coastal plain facies have been recognized from the Lower Carboniferous (Visean) Nanmingshui Formation, south of Fuyun County, Xinjiang. Fan delta facies can be further divided into fan delta plain and front subfacies. The littoral facies is mainly characterized by shoreface subfacies. The direction of paleocurrent concentrates in 320°~340°, which implies the provenance was the eastern part of Early Paleozoic Taerbahatai fold belt to the southeast of the study area. The palaeotectonic pattern of the northeast Junggar consisted of the provenance area composed by the Early Paleozoic fold belt and the Late Paleozoic passive continental margin represented by the Nanmingshui Formation on the northeastern margin of the Junggar old block during the Early Carboniferous (Visean).
