Sedimentology of silica granules and haematite in the 3.47 Ga Antarctic Creek Member, Mount Ada Basalt, Western Australia

Sedimentology, Volume 73, Issue 5, Page 1842-1866, August 2026.
ABSTRACT The Paleoarchean Antarctic Creek Member of the Mount Ada Basalt, Eastern Pilbara Terrane, Western Australia, includes beds of jasper and white chert composed of sand‐sized silica granules that often contain or are mixed with silt‐sized particles of haematite.

Source‐to‐sink sediment transport reversals during glacial sea‐level lowstands sustain soil formation on pericoastal carbonate terrains

Sedimentology, Volume 73, Issue 5, Page 1892-1910, August 2026.
ABSTRACT Understanding the processes that drive soil formation is crucial for developing sustainable land‐use strategies, as changing land‐use practices and climate change exacerbate soil erosion. The formation of substantial arable soils on carbonate bedrock requires substantial dust accretion as the underlying bedrock lacks siliciclastic material. In

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.

Synchronous Advance of the Alpine Glaciation Across the Northern and Southern Tibetan Plateau During the Mid‐Pleistocene Transition

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Chronological studies of glacial sediments from the Shishapangma and Yarlung Tsangpo River valley indicate that Quaternary glaciation on the southern Tibetan Plateau commenced at ∼0.75–0.83 Ma. However, the oldest glacial deposits in the northern plateau are dated to only ∼0.46 Ma, markedly later than the Middle Pleistocene glacial ...
