Anisotropic velocity properties and lithofacies identification of shahejie lacustrine shales. [PDF]

Sci Rep
Abstract Lacustrine shales have gained increasing attention in the global energy transition. However, their more complex lithofacies variations compared to marine shales pose significant challenges for precise reservoir characterization.

Pore-micro fracture structure, porosity and gas- bearing property of deep shale under lithofacies-formation pressure coupling [PDF]

Scientific Reports
Formation pressure-lithofacies type are the most critical factors influencing micro pore structure and porosity in shale reservoir. However, how these two factors jointly affect shale gas accumulation remains unclear.

Microbialite Diversity and Ocean Redox Geochemistry of the Late Tonian Callison Lake Formation. [PDF]

Geobiology
ABSTRACT Microbialites provide a unique insight into ancient microbial processes and environments, but trends in the diversity of unlaminated microbialites remain poorly understood. The ca. 745 Ma Callison Lake Formation in the Yukon (northwest Canada) features a range of microbialites which are diverse at both the mesoscale and microscale.
