Abstract

During the Early Cretaceous, the Paleo Pacific Plate underwent extensive subduction beneath the Eurasian continent, which coincided with substantial lithospheric thinning in the North China Craton. The Jiaolai Basin, which formed during this period, is located along the southeastern margin of the North China Craton, and is positioned between the Sulu Orogenic Belt (SLOB) and the Jiaobei Terrane (JBT). The sedimentary sequences in the basin record relevant information on the evolution of the surrounding tectonic units. Thus, this study conducted petrographic and detrital zircon U–Pb geochronological analyses on sandstones from the Lower Cretaceous Laiyang Formation in the Laiyang Sag. The findings indicate that: (1) during the Early Cretaceous, detrital sources within the Laiyang Sag displayed a distinct evolutionary pattern: early-stage deposits were primarily sourced from the JBT, with a subsequent …
