Bryozoan‐Rich Carbonate Units of the Erfoud Area (SE Morocco) Record Latest Katian to Early Hirnantian Interglacial Intervals

open access: yesGeological Journal, EarlyView.
In this study, we re‐examine the depositional architecture of the Erfoud limestone in Morocco. Introducing new biostratigraphic constraints from chitinozoan assemblages, we show that Katian to Hirnantian bryozoan‐pelmatozoan meadows reflect flooding events linked to a series of interglacial transgressions known to have occurred immediately prior to the

Lithological features of forming paleozoic collectors of the Ledyansk uplift (North Tunguska oil-and-gas area)

open access: yesИзвестия Томского политехнического университета: Инжиниринг георесурсов, 2019
The relevance of research is caused by the need to study and search oil and gas fields in the Arctic regions of Russia. As the exploration drilling of these areas is very low, the more detailed study of previously drilled wells is required for successful

Miocene to Quaternary Tectonostratigraphic Evolution of the Northern Section of the Burdur‐Fethiye Shear Zone, South‐Western Türkiye

open access: yesGeological Journal, EarlyView.
New zircon ages reveal that lacustrine sedimentation initiated in the Late Miocene (Messinian), revising earlier Pliocene age assignments. The study results support the interpretation of the northern BFSZ as a broad left‐lateral transtensional shear zone rather than a discrete sinistral fault or simple extensional graben array.

Syagoy site of Arka-Tabayakha clayey diatomite deposit: lithology of rocks and mining potential

open access: yesИзвестия Томского политехнического университета: Инжиниринг георесурсов, 2018
Relevance. Modernization of infrastructure of the oil and gas complex of Western Siberia and development of the northern territories require the widespread use of local non-metallic raw materials.

Lithology Determination with Well Log Measurements

open access: yes
In this study, it was aimed to calculate the porosity, pollution and saturation of rocks by using sonic, density, neutron and g-ray logs taken in an oil well.

Ichnology of the Rhätsandstein in the Exter Formation (Triassic), Germany

open access: yesGeological Journal, EarlyView.
Trace fossils from the Rhätsandstein of southern Germany record repeated colonization of high‐energy shallow‐marine substrates before the Triassic–Jurassic transition. The assemblage reflects environmental and preservational controls on ichnodiversity.

A Hybrid Fuzzy AHP–Fuzzy TOPSIS and GIS‐Based Framework for Mobile Clinic Location Selection in Conflict Zones: A Case Study From Northern Syria

open access: yesThe International Journal of Health Planning and Management, EarlyView.
ABSTRACT Providing healthcare services in conflict‐affected regions like northern Syria is a significant challenge due to ongoing conflict and massive displacement. Mobile clinics offer a flexible solution to meet the urgent healthcare needs of displaced communities.

Holocene vegetation dynamics of Grande Terre (Kerguelen Islands) inferred from sedimentary ancient DNA

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT While the Antarctic region has experienced significant climatic changes over the Holocene, few high‐resolution records have examined their effects on the local biota. In order to understand past ecological shifts and forecast future changes, it is important to obtain high‐resolution palaeoecological records from this region.

A High Resolution Microprobe Study of EETA79001 Lithology C [PDF]

open access: yes, 2010
Antarctic meteorite EETA79001 has received substantial attention for possibly containing a component of Martian soil in its impact glass (Lithology C) [1]. The composition of Martian soil can illuminate near-surface processes such as impact gardening [2]

New geochronological constraints on Late Pleistocene glaciation in the southern Cadí Massif, SE Pyrenees

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The Cadí Massif (42°17′09″ N, 1°38′11″ E; 2649 m a.s.l.) in the southeastern Pyrenees preserves clear evidence of Late Pleistocene glaciation, although previous research has focused almost exclusively on its northern slope. By contrast, the southern slope has remained largely unexplored.
