This study presented recently reprocessed multi-channel seismic data and multi-beam bathymetric map to reveal the geomorphology stratigraphic architecture of Yongle isolated carbonate platform in Xisha Archipelago, northwestern South China Sea. Our results show that upper slope angles exceed 10° even reach ∼32.5° whereas lower vary from .5° 5.3°. The variations margins Atoll belong escarpment (...

This paper describes the synthesis of a new biobased bis(cyclic carbonate) derived from 2,5furandicarboxylic acid (FDCA) with the incorporation of CO2. The bis(cyclic carbonate) was then used to synthesize non-isocyanate polyurethanes (NIPUs) via polyaddition reactions with a series of diamines. The chemical structures of the bis(cyclic carbonate) and the NIPUs were characterized by Fourier tra...

The Upper Triassic (Carnian–Norian) Martin Bridge Formation of northeastern Oregon, southeastern Washington, and western Idaho is characterized by rapidly shifting depositional processes within a tropical volcanic island arc setting. Martin Bridge sequences in the Hells Canyon and northern Wallowa Mountains document shallow-water peritidal evaporitic sediments that are succeeded by deeper and p...
