Role of Magma Ocean Differentiation in the Formation and Long‐Term Preservation of Distinct Geochemical Domains Within the Deep Mantle

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 5, May 2025.
Abstract We modeled the evolution of the terrestrial Magma Ocean using the short‐lived 182Hf‐182W isotope system (t1/2 = 8.9 Myr) in a multi‐reservoir early Earth. We start with a chondritic Earth at T0 = 4.567 Ga. Core segregates and attains its present‐day mass, W elemental and isotopic (182W/184W) composition by the end of core formation (TCF).

How Do Passive Margins Convert to Active Margins?

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 5, May 2025.
Abstract There has been a long debate about how passive (Atlantic‐type) margins can convert to active (Andean) margins, particularly if they can do so directly, or some other process such as an arc‐continent collision must intervene (Burke et al., 1984; Dewey, 1969, https://doi.org/10.1016/0012‐821x(69)90089‐2; Kusky & Kidd, 1985).

Salt Diapirs and Minibasins Along a Transect Across the Basque‐Cantabrian Pyrenees: Implications for Cover‐Basement Interaction During Rifting and Inversion

Tectonics, Volume 44, Issue 5, May 2025.
Abstract The Basque‐Cantabrian Pyrenees experienced Early Cretaceous rifting and latest Cretaceous to Cenozoic inversion, with the presence of prerift Upper Triassic Keuper salt influencing how deformation was accommodated. Considerable disagreement exists on the degree of decoupling of supra‐ and subsalt deformation, the amount of thin‐skinned ...

Evaluating the applicability of a 2D weighted compact gravity inversion method for determining crustal undulations and thicknesses in the Aegean region

Geophysical Prospecting, Volume 73, Issue 4, Page 1243-1254, May 2025.
Abstract This study introduces the application of the 2D weighted compact gravity inversion technique to model crustal thickness and intracrustal discontinuities in the Aegean region, encompassing both marine and terrestrial areas over a significant area of 430 km × 333 km.

A New UHP‐HP Tectono‐Metamorphic Architecture for the Southern Dora‐Maira Massif Nappe Stack (Western Alps) Based on Petrological and Microstructural Evidence

Journal of Metamorphic Geology, Volume 43, Issue 4, Page 359-383, May 2025.
ABSTRACT The southern Dora‐Maira Massif, where coesite was first discovered 40 years ago, is among the most studied and better known example of high/ultra‐high‐pressure (HP/UHP) terranes. Previous to this study, the Polymetamorphic Basement Complex of the southern Dora‐Maira Massif has been defined as a nappe stack consisting of three juxtaposed ...
