Testing the fidelity of zircon as a provenance indicator in fluvial‐fan successions: An example from the Palaeogene Colton Formation, Central Utah, USA

The Depositional Record
The stratigraphic, spatial and temporal variability of detrital zircon age populations in continental sedimentary successions is a critical tool in understanding palaeodrainage networks and how these systems distributed detritus within sedimentary basins.

Thermal history of the early Miocene Waitemata Basin and adjacent Waipapa Group, North Island, New Zealand [PDF]

, 1999
Apatite fission track (AFT) and vitrinite reflectance (VR) data for early Miocene outcrops from the Waitemata Basin reveal that the basin sequence was subjected to shallow burial before denudation.

Cryogenian Glacial Erosion and Tectonics as Agents of Crustal Recycling

Terra Nova, EarlyView.
ABSTRACT Zircon preserves evidence of recycling processes that link surface environments to the mantle. Combined δ18O‐εHf in zircon fingerprints magmatic sources and tracks how crustal material is reworked over time. We apply statistical analyses to a global compilation that apparently resolves shifts in zircon U–Pb, δ18O, and Lu‐Hf data spanning the ...

Thermo‐Tectonic History of Archean Basement Rocks in the Aktash Tagh, Southeastern Tarim Craton: Constraints From Zircon U‐Pb, Zircon and Apatite Fission‐Track Dating

Geochemistry, Geophysics, Geosystems
Stable craton lithosphere can undergo complex tectonic events at its margins due to peripheral tectonic activity. In this study, we conducted a comprehensive analysis of zircon U‐Pb dating, apatite and zircon fission‐track thermochronology on the Aktash ...

Near‐Synchronous Cambrian Evolution of the Transbrasiliano‐Kandi‐4°50′ Shear Zone in South America and Africa

Terra Nova, EarlyView.
ABSTRACT The Transbrasiliano‐Kandi‐4°50′ (TK4) shear zone in western Gondwana crosscuts South America and NW Africa for at least 6000 km. Despite its impressive size, the timing of the main episode of dextral ductile shearing is uncertain. We present detailed in situ multi‐mineral geochronology of mylonites from both Brazil and Algeria supporting that ...

Trace Element Characterisation of MAD‐559 Zircon Reference Material for Ion Microprobe Analysis

Geostandards and Geoanalytical Research, 2018
We document the composition of a natural zircon gemstone sourced from Madagascar, MAD‐559 – a new reference material for calibrating trace element mass fractions in zircon measured by SIMS.

Dating C/S Structures in Syntectonic Granites by In Situ Rb‐Sr Analyses on Muscovite

Terra Nova, EarlyView.
ABSTRACT The interplay of crystallisation, deformation and fluid–rock interactions makes deciphering geochronological information complex in syntectonic granites. In this study, we apply in situ Rb‐Sr analyses to selected samples from the Questembert Variscan syntectonic granite in Western France, which was emplaced along the South Armorican Shear Zone

THE PROLONGED INFLUENCE OF ROOT DRESSING OF CAJANDER LARCH (LARIX CAJANDERY MAYR.) ANNUAL AND BIENNIAL SEEDLINGS WITH THE GROWTH STIMULANTS ZIRCON AND EPIN ON THEIR GROWTH AT FIFTEEN YEARS OF AGE

Siberian Journal of Life Sciences and Agriculture
Cajander larch (Larix cajandery Mayr.) is the eastern race of Gmelin larch, the main forest-forming species in the Amur Region and the Primorsky Territory. It is widely used in the national economy. It is promising  for landscaping.
