Rethinking microtidal systems: Tidal signatures in the fluvial deposits of the Po River, Italy

Sedimentology, EarlyView.
ABSTRACT In microtidally influenced rivers, tides are generally assumed to leave virtually no signatures in the sedimentary record. However, this hypothesis has been surprisingly poorly tested using modern river analogues, which provide an opportunity to assess whether sedimentary signatures of microtidal regimes can develop in rivers that lack ...

Paragenetic relations of minerals in the Snezhnoye ruby deposit, Muzkol-Rangkul anticlinorium, Central Pamir

Известия высших учебных заведений: Геология и разведка
Background. The mineral association of ruby in the Snezhnoye deposit is represented by 7 rock-forming and 19 accessory minerals. Here, all minerals vary in their composition due to isomorphism.

The Material Basis of 18th‐Century Meissen Porcelain

Archaeometry, Volume 68, Issue 5, Page 908-918, October 2026.
ABSTRACT In the summer of 1708, the quest for making hard‐paste porcelain from Saxonian clay and other mineral resources succeeded. This was achieved by applying as its essential ingredient newly discovered pure kaolin from Heidelsberg near Aue, western Saxon Ore Mountains.

Escaping Russia, trapped by identity: National identity negotiation in light of ingroup wrongdoing

British Journal of Social Psychology, Volume 65, Issue 4, October 2026.
Abstract The Russian invasion of Ukraine caused a wave of emigration, with vast numbers of people fleeing Russia due to political persecution or safety concerns. The study explored how anti‐war Russian emigrants negotiate their national identity and moral responsibility amid ingroup wrongdoing.

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

Journal 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.

Consistency and Rheological Properties of Cemented Paste Backfills Prepared with Tailings with Varying Free Muscovite Content

Mining
The presence of free muscovite in tailings can negatively affect the mechanical strength and rheological properties of cemented paste backfill, as has been observed for several cementitious materials. The aim of this study is to evaluate the influence of

Porosity Preservation in Deeply Buried (8500 m) Jurassic Calcareous Mudstones of the Vienna Basin (Austria)

Terra Nova, Volume 38, Issue 5, Page 306-313, October 2026.
ABSTRACT Significant porosity of more than 5% was found at depths of more than 8500 m in poorly sorted, calcareous mudstones of the Malmian Mikulov Formation. These overpressured rocks are the main hydrocarbon source rock in the Vienna Basin. Core samples from present‐day depths of 8150 m to 8550 m were analysed using X‐ray diffraction and scanning ...

Development of unfired earthen building materials using muscovite rich soils and alkali activators

Case Studies in Construction Materials, 2019
Most studies have focused on the alkali activation of thermally activated kaolinitic clays for the production of innovative building materials. Whilst the widespread use of these minerals may be hindered due to geographical availability; a combination of

Flexural bulges and foredeep basins: Dynamic tectonic control on shifting depocentres and condensed facies, Upper Cretaceous (Santonian), Western Canada Foreland Basin

The Depositional Record, Volume 12, Issue 4, September 2026.
Allostratigraphically defined mudstone packages show marked along‐strike thickness variation, interpreted to be related to shifting thrust activity in the orogen; loading cycles lasted about 750 kyr. Close to the orogen, the forebulge is mantled by shelly sandstone whereas far from the orogen, the forebulge is typified by organic‐rich mudstone ...
