Abstract:
By integrating the achievements scored during the 1∶50000 regional geological survey, this paper systematically elucidates the sedimentology features of the Shuangqiaoshan Group in northwestern Jiangxi. This group is a gravity flow sedimentary system formed in a littoral-bathyal environment, in which there are a number of gravity flow sedimentary facies units, such as massive hybrid conglomerate facies, normal grading conglomerate facies and classical turbidite facies. In this paper the basic sequence features of these units are summarized and discussed, and on that basis, combined with the geochemical features and grain-size analysis, the sedimentary environment is preliminarily discussed.
