Porphyritic pyroxene-bearing granitolds - a strongly weathered rock group in central Finland

Fennia: International Journal of Geography, 1985
Intense preglacial weathering is associated with porphyritic pyroxene­ bearing quartz syenites, quartz monzonites, quartz monzodiorites and monzogranites, which form synorogenic stocks and batholiths in central Finland.

Crustal Architecture of the Paleo‐Pacific Rift Margin of East Antarctica: Evidence From U‐Pb Ages and O‐Hf Isotope Compositions of Ross Orogen Granitoids

Geochemistry, Geophysics, Geosystems
Granitic batholiths of the ∼500 Ma Ross Orogen in Antarctica are voluminous in scale, reflecting prolific magmatism along the active early Paleozoic convergent margin of Gondwana.

Reduced West Antarctic Ice Sheet Size During Prominent Quaternary Interglacials Constrained by Iceberg‐Rafted Debris Provenance in the Amundsen Sea

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The stability of the West Antarctic Ice Sheet (WAIS) remains a major uncertainty in sea‐level projections, and geologic records provide important constraints on its past behavior. We present 40Ar/39Ar ages of biotite and hornblende grains from iceberg‐rafted debris (IRD) in two Amundsen Sea sediment cores (PC493 and PS58/254), located south ...

Supercritical‐flow structures in a Cretaceous submarine channel–lobe transition zone, Point Loma Formation, California

The Depositional Record, Volume 12, Issue 3, June 2026.
We document meter‐scale antidune and cyclic‐step deposits in channel–lobe transition zone (CLTZ) deposits of the Upper Cretaceous Point Loma Formation in San Diego, California. These results provide new insights into sediment transport dynamics in CLTZ environments, which are critical for understanding reservoir connectivity and heterogeneity in ...
