摘要

Based on the detrital zircon U-Pb dating data, this paper discusses the provenance and constructs source-to-sink system of the Upper Jurassic in the North Yellow Sea Basin (NYSB), eastern North China Craton (ENCC). In addition, to avoid the bias of detrital zircon ages caused by variations in zircon fertility, we collected 1 709 whole rock zirconium content values (ppm) from granitic rocks with different ages in the North China Craton (NCC). Based on mean Zr content of granitic rocks in each age, these granitic rocks can be divided into four groups: Group A consists of Jurassic, Group B consists of Paleozoic, Neo-Mesoproterozoic and Neoarchean, Group C consists of Early Cretaceous and Triassic, and Group D consists of Paleoproterozoic. This research assigns to these groups zircon fertility factors (ZFF) of 1, 1.4, 1.8 and 2.2. The U-Pb age of detrital zircons from Late Jurassic sediments corrected by ZFF is statistically analyzed (K-S test, similarity, cross-correlation, linkeness, and multidimensional scaling). And combining with paleocurrent and paleogeography, we construct two source-to-sink systems: (1) Jiaodong uplift and Sulu Orogenic Belt as the source area and the North Yellow Sea Basin as the sink area; (2) Liaodong Peninsula as the source area and the North Yellow Sea Basin as the sink area.
