Description and terrestrial ages of the Calama Area Meteorite Collection (Atacama Desert, Chile)

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract We present a comprehensive study of a meteorite collection from the Atacama Desert (Chile), the driest and most climatically stable desert in the world. This collection includes meteorites from three adjacent Dense Collection Areas (DCAs) in the northern part of the Atacama Desert: Calama, Sierra Gorda, and Chug Chug, referred to as the ...

The Unexpected Discovery of Paleocene? Coals in Outcrops Thought to Be Cambrian, Al Huqf, Oman

open access: yesJournal of Petroleum Geology, Volume 49, Issue 4, Page 1179-1194, October 2026.
ABSTRACT Two brown organic deposits were encountered whilst investigating kaolinitic claystones thought to occur at the base of a Cambrian formation at outcrop. The age of these organic deposits is probably Paleocene from palynology. Organic petrography shows that they are subbituminous coals with some oil source potential.

Transforming rice production constraints into opportunities: Coordinated innovation for sustainable agrosystems in Asia

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Rice (Oryza sativa L.) production remains central to global food security, particularly across Asia, where both wetland and upland cultivation systems dominate. These agroecosystems face distinct ecological and agronomic constraints that threaten sustainable intensification.

Comparison of the Use of Cement, Gypsum, and Limestone on the Improvement of Clay through Unconfined Compression Test

open access: yesJournal of the Civil Engineering Forum, 2019
Soil stabilization is an effort to improve soil properties by adding additives in the soil to increase the soil strength and maintain the shear strength of the soil. There are many materials which can be used as stabilizers.

Climate change impacts on global wheat (Triticum aestivum L.) production: A comprehensive meta‐analysis of stressors, risks, and adaptation strategies

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Climate change is exerting profound and multidimensional pressures on global wheat (Triticum aestivum L.) production. Rising temperatures, higher vapor pressure deficit, and more frequent heatwaves reduce yields through strong, phenology‐dependent effects, with flowering and grain filling identified as the most vulnerable stages. Compound heat–
