Late Paleozoic tectonic evolution of the Qinling Orogenic Belt: Constraints and insights from detrital zircon U–Pb geochronology in the Western Qinling

Dizhi lixue xuebao
Objective  The Qinling Orogenic Belt, positioned between the Yangtze and North China cratons, has undergone a multi-stage evolution from the Paleozoic to the Early Mesozoic, fully documenting the collisional orogenic history between both cratons ...

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 ...

A database of detrital zircon U–Pb geochronology and Hf isotopes from the Songpan–Ganzi and Western Qinling terranes

Geoscience Data Journal
Since the advent of detrital geochronology, significant progress has been made in the study of sedimentary sources. The detrital zircon U–Pb age spectrum, especially when combined with zircon Hf isotopes, provides a powerful tool for determining the ...

Continental Crust Rejuvenation Across the Paleo‐Mesoarchean Transition Resulted From Elevated Mantle Geotherms

Geophysical Research Letters
The increase in initial Hf isotopes identified in early Mesoarchean detrital zircon is commonly interpreted as a reflection of the geodynamic transition from stagnant‐lid to mobile‐lid tectonics.

Detrital zircon–apatite fingerprinting challenges glacial transport of Stonehenge’s megaliths

Communications Earth & Environment
How Stonehenge’s building blocks arrived on Salisbury Plain remains debated, with glacial and human transport mechanisms proposed. Here we test the possibility of Pleistocene glacial sediment input using grain-scale U–Pb fingerprinting of detrital zircon

Detrital Zircon U-Pb Geochronology of the Dazhuyuan Formation in Northern Guizhou: Implications for Bauxite Mineralization

Yankuang ceshi, 2013
The Late Carboniferous Dazhuyuan Formation, an important bauxite bearing bed, lies along the Northern Guizhou-Southern Chongqing formation. For tracing the material source of the bauxite, U-Pb dates on detrital zircon of aluminous from Dazhuyuan bauxite ...
