Machine Learning‐Driven Classification and Production Capacity Prediction of Tight Sandstone Reservoirs: A Case Study of the Taiyuan Formation, Ordos Basin

Energy Science &Engineering, Volume 14, Issue 5, Page 2514-2538, May 2026.
On the basis of core and log data, a Bayesian‐Optimized Random Forest model achieved 92.76% accuracy in classifying tight sandstone reservoirs. A gray relational analysis‐derived evaluation index shows > 80% consistency with actual gas zones. ABSTRACT Tight sandstone gas (TSG), an unconventional oil–gas resource, has heterogeneous reservoirs ...

A Millennium of Coastside Occupation. Micromorphological Insights From the Indigenous Site of Las Estacas Cave, Tenerife

Geoarchaeology, Volume 41, Issue 3, May/June 2026.
ABSTRACT The archaeological site of Las Estacas Cave (NW Tenerife, Canary Islands) preserves some of the earliest human occupations in Tenerife, dating to the 2nd century CE, spanning the entire pre‐European time range up to the 15th century. Using soil micromorphology, this study applies a geoarchaeological approach to reconstruct site formation ...

High Geomagnetic Reversal Frequency During the Middle to Late Ediacaran (∼570 Ma) Constrained by Integrated Magneto‐ and Cyclostratigraphy

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract The Ediacaran–Cambrian (∼635–539 Ma) geomagnetic field is characterized by unusually high reversal rates and markedly weakened field strength. Estimates of these reversal frequencies can reveal key aspects of deep Earth dynamics and their potential influence on surface environments and early complex life.
