Pore Development Characteristics of Marine-Continental Transitional Shale of Benxi Formation from the Ordos Basin, China

, 2023
The mechanisms governing pore development, particularly of organic pores, in marine-continental transitional shales remain poorly constrained. This study investigated the primary controls on pore evolution within transitional shales of the Benxi ...

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.

Amber in lagoon fill facies in the Upper Albian of "Páramo de la Lora" (northern side, Palencia)

, 2003
A new discovery of in situ amber from the Lower Cretaceous series of the northern side of the "Páramo de la Lora" is reported. A detailed analysis of the outcrop section revealed facies attributed to transitional continental-marine enviroments (lagoon ...

Best Practices in Open and Reproducible Antarctic Marine Sediment Core Research

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract Marine sediment cores from Antarctica are archived by national programs for reuse and resampling by future researchers, creating a resourceful way to conduct Antarctic science. With reduced budgets to conduct Antarctic field work and to collect new sediment cores offshore of the icy continent, the accessibility of these archived cores and ...

Salt Tectonics and Inversion Style in the Southeastern Iberian Chain

Tectonics, Volume 45, Issue 11, November 2026.
Abstract The southeastern Iberian Chain is characterized by Mesozoic rift basins that were subsequently inverted during Alpine contraction. We integrate geological mapping, borehole data, balanced cross‐sections, structural restoration, and forward kinematic modeling to evaluate how rift architecture controlled Alpine deformation from basin to crustal ...
