The provenance of sediments in the Southern Okinawa Trough since the late Holocene has been a controversial scientific issue during the past 20 years. Previous studies based on isotope proxies generally indicated Taiwanese rivers as the primary source in the Southern Okinawa Trough since the late Holocene. Based on the zircon U-Pb geochronology, this study identified how sediments from the Yangtze River/East China Sea shelf had contributed significantly to the Southern Okinawa Trough in the past 624 a BP. Notably, this study found two Paleoarchean zircon grains, which indicated they originated from older orogenic belts. These data shed new light on the provenance of sediments, and a partial supply from the mainland of China cannot be excluded.

Provenance and evolution of East Asian large rivers recorded in the East and South China Seas: A review

et al. 2023

Large rivers are the arteries of continents. Those originating from the Tibetan Plateau and traversing East Asia have a relatively young history due to continuous Cenozoic perturbations. However, it has been a long journey to reconstruct their genesis and dynamic evolution, in which many puzzles and challenges remain. The river history is documented by provenance information in the ultimate sediment sinks in the East and South China Seas, but a regional-scale correlation of provenance data is still developing. Here, we explore the promise of this provenance perspective by reconstructing the evolution of three large rivers in China (the Yangtze, Pearl, and Red Rivers) by compiling and reevaluating a large volume of published provenance data (zircon U-Pb geochronology, K-feldspar Pb isotopes, and whole-rock Nd isotopes) from both Cenozoic strata and modern sediments from the East and South China Seas and the large river basins. Unlike traditional approaches that average provenance signatures, intersample variability was carefully evaluated. The general inheritance of zircon age spectral patterns and small fluctuations of Nd isotopes in the Neogene strata suggest provenance stabilization in the East and South China Seas and the establishment of near-modern drainage configurations. The paleodrainage basins before the Miocene are interpreted to have been smaller than their modern sizes, and drainage expansion likely occurred over the Oligocene. Our analysis suggests that the widely accepted models that link drainage between the ancient Yangtze and Red Rivers may be unlikely. The compiled provenance signatures and prior paleocurrent measurements of Paleogene strata distributed in the southeastern Tibetan Plateau margin show sediment supplied from local terranes instead of through-flowing river systems.
