Geochemistry, Geophysics, Geosystems, Volume 26, Issue 5, May 2025.Abstract Detailed geochronology from two compositionally distinct generations of dikes and sills intruded into the Alta metamorphic aureole, north‐central Utah, complement previous geochronologic studies from the Alta stock, providing information on the timing of magmatism and the nature of emplacement.

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 5, May 2025.Abstract High heat fluxes occurring in rift settings are expected to generate partially melted low‐pressure–high‐temperature granulites (LP–HTG). Therefore, studying these rocks can offer valuable insights into crustal reworking during extension. However, our interpretations are limited by the rarity of LP–HTG in the metamorphic record.

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 5, May 2025.Abstract The identification and real‐time monitoring of geofluids during drilling is crucial for safe drilling operations and can provide valuable insights into reservoir properties and fluid migration. While mud gas logging is well established in oil and gas exploration, recent interest in natural hydrogen (H2) and helium (He) exploration has prompted

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 5, May 2025.Abstract Post‐collisional mafic rocks not only record geodynamic processes at the end of the orogenic cycle but also retain various clues regarding preceding interactions between subducted slabs and mantle wedges. However, the latter and related indicators have often been overlooked; in particular, how the continental crust interacts with the mantle in

Geobiology, Volume 23, Issue 3, May/June 2025.ABSTRACT Shallow‐marine environments are thought to have been pivotal to the spreading, perhaps even the origin, of early life on Earth. The shallow‐marine Archean sedimentary record of early life, however, is biased towards carbonates; nearshore siliciclastic environments have not received proportional attention.
