GeosciencesThe observed shortage of water resources in the western and southern regions of the Russian Federation may soon affect the territory of the Republic of Bashkortostan. An increase in the share of groundwaters can help to solve this problem. To provide the

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.Abstract Vulcanian eruptions are classically associated with the launch of ballistic ejecta and particularly with the production of breadcrust bombs. Morpho‐textural analysis of these ejecta provides critical insight into the poorly constrained processes controlling the complex dynamics of Vulcanian activity.

Investigating Layered Cratonic Lithosphere in the Fennoscandian Shield
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.Abstract Cold, thick, and chemically depleted lithosphere with high seismic velocity and low attenuation characterizes continental cratons. However, discrepancies between xenolith‐based thermal constraints and those inferred from surface‐wave seismic models, together with the widespread observation of mid‐lithosphere discontinuities, challenge the ...

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.Abstract Same‐dip double subduction (SDDS), in which two parallel slabs dip in the same direction, has been linked to accelerated plate motion in both modern and ancient convergent systems, such as the Late Cretaceous Africa–Eurasia system. Yet a systematic framework for quantifying how SDDS alters plate kinematics in a large‐scale spherical geometry ...

Zoning and the Distribution of Locational Rents: An Empirical Analysis of Harris County Texas [PDF]
The Coase theorem presents two criteria for evaluating regulation. The first is how successful the regulation is at reaching the efficient outcome relative to private solutions.

Petrology of Gameleira potassic lamprophyres, São Francisco Craton
Anais da Academia Brasileira de Ciências, 2012 Gameleira lamprophyres are dykes and mafic microgranular enclaves associated with the shoshonitic Gameleira monzonite. This association belongs to the Paleoproterozoic alkaline magmatism from Serrinha nucleus, northeast Brazil.

Tracking Deep Mantle Melting on Mars Using Phobos Tides
Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.Abstract We study the deep internal structure and rheological state of Mars by analyzing its response to tidal forces exerted by Phobos and by introducing a melt fraction in the mantle layers. Motivated by recent seismic evidence for a basal molten layer near the base of the Martian mantle, we explore the distribution of melt within the mantle and its ...

Geobiology, Volume 24, Issue 5, September/October 2026.ABSTRACT The Carri Laufquen Lakes System is a highly alkaline, basalt‐hosted lacustrine environment in northern Patagonia, Argentina. Diverse morphologies of Late Pleistocene sub‐fossil stromatolites occur along the lakeshores. Using detailed optical and electron microscopy, spectroscopy and organic geochemical analyses, this study shows that ...
