An integrated facies, MS and XRF‐based approach applied to the Tithonian–Berriasian Sidi Khalif Formation (central Tunisia) resolves five Tithonian and eight Berriasian third‐order sequences, showing how mixed carbonate–siliciclastic shelves record coupled eustatic, climatic and tectonic controls and providing a transferable template for similar mud ...

AI‐assisted identification of stromatoporoids
AI models integrating vertical and transverse thin‐section images accurately classify Silurian stromatoporoid taxa, achieving up to 97% accuracy. This dual‐orientation framework mirrors traditional taxonomy, reveals patterns of morphological continuity, and provides a scalable, quantitative approach for advancing automated fossil identification ...

Composition and Provenance of Victoria Group Sandstones in Southern North Victoria Land, Antarctica
Three distinct source areas contributed to sandstones of the Victoria Group within the Transantarctic Basin in southern North Victoria Land. During the Permian, quartzose sandstones were derived from erosion of the local Ross Orogen, likely from an uplifted swell in the area of today's Ross Sea, the Ross High.

Beach Gold and Heavy Mineral Concentrates on Tiwai Spit Gravel Strand Plain, Southland, New Zealand
The Holocene Tiwai Spit on Foveaux Strait is a 12 km by 2 km gravel‐dominated strand plain, ∼10 m above present sea level. Gravel clasts are dominated by well‐rounded quartz cobbles, pebbles and granules derived from Otago Schist 200 km to the north in evolving river drainage systems during late Cenozoic.

ABSTRACT Integrated earth modelling aims to combine all available geoscientific information to derive one common earth model. However, combining multiple parameters in a meaningful way remains challenging. In this study, we aim to improve mineral exploration workflows through the integration of new magnetotelluric data with other geophysical and ...

ABSTRACT Natural inland wetlands in Southeast Asia provide key biodiversity, hydrological, carbon‐storage and livelihood functions, but are increasingly affected by land‐use change, fire, hydrological modification and climate change and variability.

Abstract Headwater catchments provide essential water and nutrients to downstream ecosystems. The timing and evolution of their transport is shaped in part by the “invisible” subsurface structure but have been largely unexplored at the watershed scale.

Slope and sediment size in the development of pebble and cobble beaches with low permeability
We studied beaches composed of coarse‐grained beaches. In spite that the occurrence of an impermeable layer at a low depth that reduces its permeability, the correlation between the beach slope and the sediment size corresponds to what was expected, and the underlying and cohesive sediment reached the same slope of the beach.
