Composition and spatiotemporal evolution of the mixed turbidite-contourite systems from the Middle Ordovician, in western margin of the North China Craton

Sedimentary Geology, 2021
Accurately identifying contourites and analysing the interaction between turbidity flows and bottom currents from the mixed turbidite-contourite systems (MTCSs) in the deep-sea environments are still challenging.

Development characteristics and mechanisms of damage-causing urban ground fissures in Datong City, China

Engineering Geology, 2020
A set of widely developed ground fissures within the Datong Basin, northern China, have inflicted serious damage to farm fields, roads, houses, and building foundations in Datong City. Such emergence of large-scale ground fissures is rare in urban areas.

Interflag sandstone laminae, a novel sedimentary structure, with implications for Ediacaran paleoenvironments

Sedimentary Geology, 2019
Interflag sandstone laminae are thin, silty to sandy, layers between thicker sandstone beds, and a new name for sedimentary structures recently called “shims”, and “microbial mat sandwiches”, from Ediacaran fossil localities of Nilpena, South Australia ...

When a mudstone was actually a “sand”: Results of a sedimentological investigation of the bituminous marl formation (Oligocene), Eastern Carpathians of Romania

Sedimentary Geology, 2019
The bituminous marl formation (BMF) is an important source rock in Romania. At the study location, in the Eastern Carpathians, the BMF composition is dominated by calcite (coccolith debris, cement) and diagenetic silica, with the remainder consisting ...

The origin and impact of the Shizhuang ground fissure, Yingxian area, Datong Basin, China

Engineering Geology, 2019
The Datong Basin is part of the regionally extensive Fenwei Graben System, a major tectonic zone impacted by active tectonics and the resulting damage to life and infrastructure. The basin also contains the Shizhuang ground fissure system. In this study,

Carbon mineralization using plagioclase feldspar-rich mine tailings: characterization and cation extraction

, 2021
The possibility to capture and store CO2 in mine tailings has gained significant traction as a viable climate mitigation technique. The mineralogy and chemistry of mine tailings can vary drastically depending on the type of mine and local geology ...
