Ordovician magmatism in the Pyrenees
, 2017 Successive Ordovician magmatic pulsations are well documented in the pre-Variscan basement of the Pyrenees. According to radiometric data, magmatism lasted about 30 m.y., from ca. 477 to 446 Ma, and although the magmatic activity seems to be continuous, two peaks can be distinguished at 473-472 Ma and 457 Ma.

Journal of Extracellular Vesicles, Volume 14, Issue 9, September 2025.ABSTRACT Tumour progression depends on the bidirectional interactions between cancer and stroma in the heterogeneous tumour microenvironment (TME) partially through extracellular vesicles (EVs). However, the secretary mechanism and biological effect of cancer cell derived EVs on tumour survival under starvation is poorly defined.

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 9, September 2025.Abstract The Andean margin of Central Chile (∼32°40′–34°30′S) records abundant Cenozoic arc magmatic activity with variable compositional characteristics. This is examined through the analysis of an extensive database of new and published whole‐rock geochemistry and Sr‐Nd isotopic compositions, in addition to zircon Hf and O isotopic compositions.

Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.Abstract Inversions of satellite observations of the lunar crustal magnetic field do not consistently produce regional magnetization directions consistent with a selenocentric axial dipolar field. We modeled the thermal evolution of anomaly source bodies in the lunar crust and found that large features (impact melt sheets and ejecta deposits) cool ...

Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.Abstract We present a comprehensive study of a new Martian meteorite, Northwest Africa (NWA) 16788, found in the Sahara Desert in July 2023. This specimen constitutes the largest known individual meteorite of Martian origin, with a total weight of ⁓25 kg. A detailed mineralogical and geochemical investigation identifies NWA 16788 as an enriched olivine
