Introduction to the Dinaric Karst

open access: yes, 2010
Dinaric karst is expansive, 800 km long and up to 150 km wide area of karst, which extends over majority of Dinaric mountains and therefore also over the southwestern part of Slovenia.

Geology-engineering integration mode of ultra-deep fault-karst reservoir in Shunbei area, Tarim Basin

open access: yes, 2021
The exploration and development practice in Shunbei area of Tarim Basin shows that oil and gas resource there is rich. However, the reservoir is deeply buried, the degree of oil and gas enrichment varies greatly, the reservoir type is very complex, and ...

3D geological modeling of mine karst geothermal reservoir and geothermal resources evaluation

open access: yesMeitan xuebao
The traditional geothermal reservoir volume method is suitable for the evaluation of geothermal resources in large-scale regions, but there is a significant error when it is used for the evaluation of mine geothermal resources.

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.

Ectomycorrhizal Cortinariaceae species dominate class II peroxidase gene expression in a boreal forest soil

open access: yesNew Phytologist, Volume 252, Issue 1, Page 400-413, October 2026.
Share of transcripts and ITS2 sequence for each gene families among identified fungal contigs and OTUs. Summary Boreal forest ecosystems constitute a large terrestrial reservoir of carbon. In these nitrogen‐limited environments, release of nutrients through decomposition of soil organic matter is of fundamental importance.

Reconstructing large‐scale karst paleogeomorphology at the top of the Ordovician in the Ordos Basin, China: Control on natural gas accumulation and paleogeographic implications

open access: yesEnergy Science & Engineering, 2019
Karstification in carbonate successions has an important influence on hydrocarbon accumulation. Taking the Ordos Basin, currently the largest petroliferous basin in China, as an example, this study examines the large‐scale, long‐term (~120 Myr ...

From Core to Field: Pattern Selection in Dissolving Fractures

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Chemical erosion governs the evolution of fractures across Earth systems, which manifests in three distinct dissolution patterns. However, how the boundaries between these regimes depend on system scale remains an open question, and no predictive theory has successfully linked laboratory observations to field‐scale behaviors. Here we integrate

Application of comprehensive detection techniques in leakage analysis of karst reservoirs

open access: yesCarsologica Sinica
The reservoir is located in Fengdu county, Chongqing Municipality. After impoundment, karst collapses occurred successively on both the left and right banks at the reservoir tail. Reservoir water rapidly leaked through sinkholes within the collapse pits,

High Tree Species Diversity Promotes Thermal Enhancement Response of Microbial Carbon Use Efficiency

open access: yesAdvanced Science, Volume 13, Issue 53, 24 September 2026.
ABSTRACT Predicting soil carbon dynamics under warming is constrained by limited understanding of microbial thermal adaptation, particularly whether microbial carbon use efficiency (CUE) can adapt to warming and how plant diversity modulates this response. Using soils from a natural tree species diversity gradient in a subtropical forest, we combined a
