Sedimentology, EarlyView.ABSTRACT Shelf‐edge deltas are commonly interpreted to record basinward facies migration across uninterrupted, gently dipping shelf margins; however, examples from mixed siliciclastic‐carbonate margins reveal more complex depositional dynamics. Periods and areas of carbonate sedimentation within mixed siliciclastic‐carbonate margins can modify shelf ...

Sedimentology, EarlyView.ABSTRACT Classical models of formation of sedimentary siliceous rocks (flint, chert, opoka) commonly assume that the Cretaceous marine silicon (Si) cycle was primarily biologically controlled, broadly analogous to the modern ocean. In this framework, siliceous sponges are regarded as the principal source of dissolved silica (dSi) to sediment porewaters,

U–Pb Dating of Cambrian Magmatism in the Pinerolo‐Sanfront Unit, Dora‐Maira Massif (Western Alps)
Terra Nova, EarlyView.ABSTRACT The Pinerolo‐Sanfront Unit (PSU), the structurally lowest tectonic unit of the Dora‐Maira Massif (Western Alps), has been regarded as a monocyclic unit composed of Permo‐Carboniferous sediments and Permian granitoids that were metamorphosed during the Alpine orogeny.

Geoscience Data Journal, Volume 14, Issue 1, January 2027.3D visualisation of an integrated borehole dataset together with the LHC and SPS tunnel alignments. As the figure illustrates, the geological composition varies between the SPS and LHC tunnels. Near the SPS tunnel, sandstone and marl are the most common rock types, while between Points 3 and 4 along the LHC tunnel, limestone dominates.

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives
Biological Reviews, Volume 101, Issue 6, Page 2839-2873, December 2026.ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.

Selected Physical and Geotechnical Properties of Loess in Wairarapa Valley, New Zealand
New Zealand Journal of Geology and Geophysics, Volume 69, Issue 4, December 2026.Loess up to 10 m thick covers marine terraces, old river aggradation terraces, and gentle hill country slopes in Wairarapa, New Zealand. In the drier eastern and southern parts of Wairarapa, the loess is subject to dry summer and autumn and wet winter and spring in most years.

Placer Gold in the Eastern Maniototo Basin, Otago, New Zealand: Deposits and Sources
New Zealand Journal of Geology and Geophysics, Volume 69, Issue 4, December 2026.Abundant detrital gold particles in placer deposits of eastern Maniototo basin, southern South Island, New Zealand, have only minor rounding and retain many angular and crystalline features, implying derivation from a nearby source. Likewise, gold particle interior textures have undergone only minor transport‐induced deformation and recrystallisation ...
