The Depositional Record, Volume 12, Issue 4, September 2026.This study compares primary dolomite precipitation in modern and ancient environments, varying from coastal to transitional to continental saline environments. The microbially mediated dolomites are characterised by high Sr concentrations. Here, various geochemical proxies are studied and compared to previous findings.

Evaluation of Drillability of the Mahu Conglomerate Formation in Xinjiang, China
Energy Science &Engineering, Volume 14, Issue 9, Page 4095-4112, September 2026.This graphical abstract illustrates the workflow for developing an optimized prediction model using measurement while drilling (MWD) data. A total of 90 MWD cases are divided into a training set (80%) and a test set (20%). Four logging‐while‐drilling parameters—compensation density, acoustic travel time, resistivity, and neutron porosity—are selected ...

Permeability and Induced Polarization of Mudstones
Water Resources ResearchElectrical measurements can be used to estimate hydraulic properties such as permeability (k) in sedimentary rocks. Previous work has focused on sandstones, siltstones, and carbonates, while investigations on mudstones have rarely been reported.
