Description and terrestrial ages of the Calama Area Meteorite Collection (Atacama Desert, Chile)

Meteoritics &Planetary Science, EarlyView.
Abstract We present a comprehensive study of a meteorite collection from the Atacama Desert (Chile), the driest and most climatically stable desert in the world. This collection includes meteorites from three adjacent Dense Collection Areas (DCAs) in the northern part of the Atacama Desert: Calama, Sierra Gorda, and Chug Chug, referred to as the ...

First records of Boreolithothamnion astragaloi and Boreolithothamnion soriferum (Hapalidiales, Rhodophyta) from Japan with the characterization of Boreolithothamnion japonicum from Hokkaido based on molecular and morpho‐anatomical analyses

Phycological Research, EarlyView.
SUMMARY Boreolithothamnion is a non‐geniculate coralline red algal genus distributed in cold to warm temperate regions of the Northern Hemisphere. Since the establishment of the genus in 2023, following the redefinition of the genus Lithothamnion, its species diversity and distribution of Boreolithothamnion in Japan needed to be reassessed.

Kelp‐boulder transplants for habitat restoration

Restoration Ecology, EarlyView.
Abstract Introduction Degraded habitats present a major barrier to the survival and recovery of threatened marine species, particularly where structural or biogenic complexity has been lost, and natural regeneration ability is uncertain. Despite growing interest in habitat restoration, techniques rarely deliver rapid improvements at the necessary ...

Geochronological and geochemical constraints on juvenile continental crust formation in the Eocene Luzon intra-oceanic arc, Philippines

Geoscience Letters
The formation of juvenile felsic crust in intra-oceanic arcs (IOAs) represents a fundamental but poorly understood process in Earth's crustal evolution.

Not all rhodoliths need a bed–depositional mechanisms in shallow water Sporolithon nodosum rhodoliths from the Whangaparaoa peninsula (North Island, New Zealand)

Sedimentology, EarlyView.
ABSTRACT Rhodoliths, formed by crustose coralline algae (CCA), are prominent components in carbonate platform deposits, contributing to the characteristic rhodalgal facies. Their formation is influenced by both biological and physical factors, and under specific conditions, they can accumulate, forming extensive rhodolith beds.

Contourite erosional and depositional features of the Maastrichtian chalk on Jasmund peninsula (Rügen island, NE Germany)

Sedimentology, EarlyView.
ABSTRACT Seismic‐scale features such as deeply incised submarine valleys and mounded drifts together with ichnological features indicative of discontinuous sedimentation and erosional episodes have recently been documented from the Upper Cretaceous chalk in the southern Baltic Sea area.

Early development of anoxia prior to the main euxinic phase of the Jenkyns Event on the margin of the Western Tethys (Sachrang Basin, Eastern Alps)

Sedimentology, EarlyView.
ABSTRACT Although the global expansion of oxygen‐depleted marine environments during the Early Toarcian Jenkyns Event (or Toarcian Oceanic Anoxic Event) is primarily inferred from successions in the NW European epicontinental basins, the timing of the expansion of anoxia in Tethyan basins, where hydrography potentially played a minor role, is poorly ...

Origin of the King's Trough Complex (North Atlantic): Interplay Between a Transient Plate Boundary and the Early Azores Mantle Plume

Geochemistry, Geophysics, Geosystems
The King's Trough cuts into an area of thickened oceanic crust associated with the 45°N melting anomaly at the Mid‐Atlantic Ridge. Here we present a comprehensive geochemical data set and new 40Ar/39Ar age and bathymetric data from magmatic rocks from ...
