Carboniferous basement rocks of northern Britain [PDF]

open access: yes, 1987
The study of Carboniferous basement rocks of northern Britain has concentrated on the dominantly clastic rock succession which unconformably overlies the Lower Palaeozoic basement and occurs beneath the lowermost Carboniferous limestones in areas ...

Fracture evolution of a thick soft protection layer and the water inrush mechanism in overburden under longwall mining

open access: yesDeep Underground Science and Engineering, EarlyView.
Through shear–tensile creep tests and viscoelastic modeling, the fracture evolution of thick soft protective layers is clarified. Results show thickness‐dependent rheological failure modes that govern four types of roof water inrush, providing a mechanism‐based framework for hazard prediction and control. Abstract In the Jurassic coal‐bearing strata of

Mineralogical, Elemental, and Spatial Variability of Volcaniclastics in Fluvio‐Coastal‐Aeolian Sedimentary Systems and Their Insights for Mineral Sorting on Mars

open access: yesEarth and Space Science, 2022
This study investigates the mineralogical, elemental, and spatial variability from source (proximal) to sink (distal) of Merapi basalt‐andesitic stratovolcano (Java, Indonesia) to better constrain volcaniclastic mineral sorting in fluvial, aeolian, and ...

The origin of massive sandstone facies in an ancient braided river deposits [PDF]

open access: yes, 1995
Lateral profiling techniques have been utilised to define the three-dimensional fluvial architecture of the Fell Sandstone Group (Arundian-Holkerian) of the Northumberland Basin, UK; the Lee-type sandstones (Morrowan-Atokan) of the central Appalachian ...

Multifactorial Screening for Fine‐Scale Selection of CCS Industrial Clusters and Hubs in Brazil

open access: yesGreenhouse Gases: Science and Technology, EarlyView.
ABSTRACT As Brazil moves toward implementing its decarbonization commitments, carbon capture and storage (CCS) hubs are emerging as a key pathway for large‐scale CO2 abatement in hard‐to‐abate sectors. This paper presents a multifactorial, data‐driven framework to screen and prioritize potential CCS industrial clusters and hubs across Brazilian regions,

Volcanogenic Fluvial-Lacustrine Environments in Iceland and Their Utility for Identifying Past Habitability on Mars

open access: yesLife, 2015
The search for once-habitable locations on Mars is increasingly focused on environments dominated by fluvial and lacustrine processes, such as those investigated by the Mars Science Laboratory Curiosity rover.

Mesozoic–Cenozoic Thermochronology of the Tarim–Southern Tianshan System, NW China

open access: yesGeological Journal, EarlyView.
Tectonothermal history of the Tarim–Southern Tianshan system compared with the major tectonic events at far‐field plate margins. ABSTRACT The Tarim Basin, an oil‐bearing basin in northwest China, is tectonically and sedimentologically linked to the Southern Tianshan Orogenic Belt.

Contraction of the fluvial territory in the Jarama River (Spain)

open access: yes, 2023
Rivers are dynamic systems, with mobility due to their changing flows. Variations in flow give rise to floods, forming floodplains, whose human occupation depends on the probability of flooding; the reduction of floods favours human occupation.

Molecular Palaeontology Prospects From Exceptionally Preserved Eocene Brackish‐Water Bivalve Batissa sitakaraensis (Venerida: Corbiculidae) From Hokkaido, Japan

open access: yesGeological Journal, EarlyView.
This study reports the exceptional preservation of the Eocene freshwater bivalve Batissa sitakaraensis from Hokkaido, Japan. Multimodal analyses reveal that both the aragonitic shell mineralogy and the delicate organic periostracum retain their original structural and chemical characteristics after millions of years.

Satellite ASTER Mineral Mapping the Provenance of the Loess Used by the Ming to Build their Earthen Great Wall

open access: yesRemote Sensing, 2020
The earthen border wall (Great Wall) built by the Ming is largely made of wind-blown loess. However, does the composition of this loess change along the length of the wall in response to variations in regional sediment transport pathways and impacting on
