The Seismic Expression of Core Complex‐Style Extensional Detachment Faults in Rifted Margins

Terra Nova, Volume 38, Issue 4, Page 251-258, August 2026.
ABSTRACT The identification of core complex‐style extensional detachment faults (CCDFs) in rifted margins is crucial for accurately restoring their stratigraphic and thermal histories. Yet recognising CCDFs in seismic reflection images is challenging due to their faint topographic expression; the lack of associated abrupt offset in seismic reflections;

Tree‐Ring Oxygen Isotope Values During the Last Glacial Maximum and Insights to Future Changes in Climate

Terra Nova, Volume 38, Issue 4, Page 259-265, August 2026.
ABSTRACT Annual tree‐ring oxygen‐isotope values were measured from sections of two fossil logs of Picea mariana (black spruce) recovered from last glacial maximum proglacial sediment in Illinois, USA. Collectively, the specimens date from ca. 25,130 to 24,720 cal years BP.

Ductile Extrusion Triggered by Continental Collision in NE Brazil

Terra Nova, Volume 38, Issue 4, Page 266-277, August 2026.
ABSTRACT The Borborema Province in northeastern Brazil hosts one of the world's largest strike‐slip shear zone networks, active during the late Neoproterozoic assembly of West Gondwana. Whether these shear zones initiated during active continental collision or as a post‐orogenic response to far‐field stresses remains debated.

Emergence of Continents Stabilized the Bioavailability of Boron

Terra Nova, Volume 38, Issue 4, Page 278-284, August 2026.
ABSTRACT Boron is an essential element for the development of life on Earth; borates stabilize ribose in prebiotic reactions and facilitate metabolism in higher plants. There is, however, a relatively narrow surface boron concentration range over which borates stabilize and serve as a micronutrient rather than a toxin.

Global Cooling Driving the Increase in Erosion Rates Across the Himalaya Since the Quaternary

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Late Cenozoic global cooling is well documented, yet its impact on erosion rates in active mountain belts, particularly after the onset of Quaternary glaciation, remain contentious. This ambiguity partially stems from the potential methodological biases in erosion rate quantification, particularly in the Himalaya, where recent studies report ...
