Hydrological evolution and biogeochemical feedbacks controlling organic carbon accumulation in an Eocene saline lake

Jian-Hua Zhao, W. X. Zhang, Keyu Liu, Qinhong Hu et autres

Organic carbon (OC) accumulation in lacustrine basins is commonly attributed to sustained anoxia and high primary productivity, yet the role of dynamic hydrological reorganization in carbon preservation remains poorly constrained. Here, we integrate multi-proxy sedimentological and geochemical data from the Eocene Kongdian …

Effects of lamina on petrophysical properties and brittleness of shales: Insight from lamina-scale experiment and fracture propagation simulation

Yuqi Wu, Jiabao Yang, Ke-Yu Liu, Chao-Zheng Deng et autres

Accurate shale characterization is hampered by the lack of high-resolution analytical techniques to probe the in situ petrophysical and mechanical properties at the lamina scale. Here we report for the first time a comprehensive lamina-scale experimental characterization and numerical simulation, including AMICS, …

Controls on the organic carbon content of the lower Cambrian black shale in the southeastern margin of Upper Yangtze

Yu-Ying Zhang, Zhi-Liang He, Shu Jiang, Shuangfang Lu et autres

Control of various factors, including mineral components, primary productivity and redox level, on the total organic carbon (TOC) in the lower Cambrian black shale from southeastern margin of Upper Yangtze (Taozichong, Longbizui and Yanbei areas) is discussed in detail in this article. …
