A missing continental impact melt sheet signal in the early Earth detrital zircon record [PDF]
Impact-derived melting has been proposed as a significant process in the formation of Earth’s early crust which could mean that impact melts are a source for Earth’s oldest minerals including ancient zircons. However, the source lithology of many Archean

Using detrital zircon to reconstruct Neoproterozoic crustal thickness variation in the northwestern margin of the Yangtze Block [PDF]
Trace element geochemistry and chronology of zircon are reliable tools for reconstructing sediment provenance and crustal evolution, particularly in contexts where early crustal and rock records are sparse.

New insights on the geochemical affinity and age of mineralized rocks in Timok magmatic complex, East Serbia [PDF]
Bor and Čukaru Peki are world-class porphyry deposits spatially and genetically associated with the Cretaceous Timok magmatic complex. This research was conducted to determine the age and geochemical affinity of the magmatic rocks that formed these ore ...

Magmatism has profoundly influenced the evolution of the geosphere, hydrosphere, atmosphere, and biosphere in back-arc basins. However, the timing of the magmatism in the Okinawa Trough (OT) is not well constrained by the age spectra of zircons.

In the Ordovician limestone of the Thorsberg quarry (South Sweden), about 130 meteorites have been found. Among the extraterrestrial material, several terrestrial Cr-spinels and zircons have been found too. In particular, in the interval 416–447 cm above

Nature of zircon clastics in the Riphean and Vendian sandstones of the Southern Urals
New age dates of detrital zircons of terrigenous rocks augmented the possibilities of interpretation of their provenance. Unfortunately this interpretation is restricted by a formal comparison of age-and-composition characteristics of detrital crystals ...

Provenance and tectonic implications of the Yanshi bauxite area in Western Henan, China [PDF]
The bauxite layer in Western Henan supplies a large number of bauxite ores and is useful for studying tectonic movement. In this paper, the bauxite samples were selected to carry out LA-ICP-MS detrital zircons U-Pb dating and Hf isotope testing.
