Middle Jurassic–Lower Cretaceous Depositional Facies Evolution and a Fan-Delta–Beach-Bar Model Based on a Case Study from the Anjihai Section in the Southern Junggar Basin

Lake-margin successions preserve interactions between terrestrial sediment supply and lacustrine deposition. We examined the Toutunhe–Qingshuihe succession at the Anjihai section in the western sector of the southern Junggar Basin using outcrop logs, lithofacies descriptions, sed...

Digital Transformation and Operational Efficiency in Petroleum Enterprises: Mechanisms and Panel Evidence from Chinese A-Share-Listed Firms, 2008–2024

Amid the rapid development of the digital economy and China’s carbon-peaking and carbon-neutrality goals, digital transformation has emerged as a critical pathway for petroleum enterprises to improve quality and efficiency. However, the mechanisms linking digital transformation t...

Early Ediacaran micro- and macro-fossils from South China provide insights into post-Snowball Earth marine ecosystem

Abstract Understanding of biological and ecological dynamics after the terminal Cryogenian Marinoan glaciation remains limited because the early Ediacaran fossil record is sparse and taphonomically biased toward microfossils. Here we show an early Ediacaran fossil assemblage from...
