Crustal Structure of the J Magnetic Anomaly at 31°N, Northern Central Atlantic
Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.Abstract The J magnetic anomaly in the Central Atlantic has 10 times larger amplitude than surrounding seafloor‐spreading magnetic lineations and is often associated with thick oceanic crust formed by excess magma. The anomaly has also been identified in the southern North Atlantic, where it has been linked to the onset of seafloor spreading ...

Papers in Palaeontology, Volume 11, Issue 6, November/December 2025.Abstract The Villaggio del Pescatore (VdP) fossil Lagerstätte represents the most significant Upper Cretaceous (lower–middle Campanian) palaeontological locality in Italy and the Mediterranean region. We present the first systematic revision of the VdP fossil assemblage with a focus on its previously undescribed arthropod fauna, providing new insights ...

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.Abstract Continental breakup involves multiple extension styles; each linked to unique structural and sedimentary processes. High‐angle, low‐angle, listric and antilistric normal faults develop at different stages and positions during rifting. The Bay of Biscay and its margins, a prototypical example of magma‐poor rifted margins during Jurassic ...
