英文摘要 | Using isotopic dating of tuff, heavy mineral and lithofacies, correlation of Jurassic strata on the northern margin of the Dabie orogenic belt (DOB) has been enabled in the Fenghuangtai, Zhougongshan, Maotanchang and Jingangtai formations, which might be as young as Early Cretaceous. Depositional systems have been interpreted as mainly alluvial fan, braided stream and overbank, secondarily fan-delta and lacustrine. The palaeocurrent systems of the Jurassic-Cretaceous basins can be divided into two classes: one transverse adjacent to the southern margin, the other longitudinal close to the middle flowing from west to east. Mesozoic sedimentary source rocks are mainly from the DOB and, according to their geochemistry, experienced evolution in a volcanic arc tectonic setting. The Jurassic-Cretaceous strata have been subdivided into four Chronosomes, and their overlapping progressively from east toward west implies that exhumation of the DOB characterized diachronous. Based on stratigraphic evidence from eclogite conglomerates found in the Maotanchang and Fenghuangtai formations, the first exposure of UHP (ultra-high pressure) rocks in the DOB occurred in Jurassic-Lower Cretaceous time. Further, phengites and Triassic zircons found in the Lower Jurassic Fanghushan Formation suggest that denudation began in the Early Jurassic. |
