Regionalized Formation and Recycling of New Venusian Crust at Chasmata
The Planetary Science JournalVenus and Earth are geologically active in ways distinct from each other. Earth exhibits plate tectonics, where the primary resurfacing mechanism is crust formation along a globe-girdling, extensional tectonic setting in mafic crust, the mid-ocean ridge (

Journal of Petroleum Geology, EarlyView.ABSTRACT The diagenetic albitization of plagioclase and K‐feldspar grains is a transformative process that significantly alters sandstone's detrital composition and formation water chemistry, impacting reservoir quality. In this study, Eocene turbidite sandstones from the offshore Espírito Santo Basin, Brazil, were investigated to elucidate the role of

Sedimentology, EarlyView.ABSTRACT Microporous carbonate rocks typically record complex diagenetic histories driven by microbial activity and fluid interactions within multiple diagenetic environments. The relative roles of meteoric and burial diagenetic processes in pore evolution remain debated, particularly within Cretaceous carbonate systems of the Middle East, as does the ...

Cenozoic tropical carbonate platforms in the Santos Basin, SE Brazilian Margin
Sedimentology, EarlyView.ABSTRACT Tropical carbonate platforms accompanied the latitudinal shifts of the tropical belt throughout the Cenozoic. Their flat‐topped geometries were influenced by a specific set of processes, including climate and sea‐level changes, carbonate facies, tectonics and continental runoff.

Sedimentology, EarlyView.ABSTRACT Previous studies have documented genetic divergence within the last few million years between northern and southern populations of terrestrial plants and animals along the Baja California peninsula, with many studies hypothesising that the divergence is due to an ancient seaway that crossed the central peninsula and created a physical barrier ...

Terra Nova, EarlyView.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 ...

Fault‐Controlled Permeability: A Key Parameter in Geothermal Electricity Production Assessment
Terra Nova, EarlyView.ABSTRACT Geothermal energy is central to the global green energy transition, but its development has long focused on regions with positive thermal anomalies. Through a semi‐quantitative global‐scale review and spatial analysis of 361 geothermal sites, we show that 56.2% of global geothermal electricity production occurs in regions with thermal ...
