Pyrite is one of the important components of shale and plays a crucial role in shale gas
enrichment. However, currently there are just a few studies on this subject matter. Therefore …

Hybrid microbial, skeletal, and abiotic carbonates have changed over time and space on
various scales, and are key to understanding sedimentological and palaeoecological …

The reefs in the **annüdong Formation (Cambrian Series 2) are the oldest archaeocyathan–
