Discussion on Detrital zircon geochronology of the Carboniferous Baixo Alentejo Flysch Group (South Portugal); constraints on the provenance and geodynamic evolution of the South Portuguese Zone, Journal, vol. 172, 294-308 [PDF]
In their recent study, Rodrigues et al. (2014) attempted a provenance analysis of the Carboniferous Baixo Alentejo Flysch Group (SW Iberia), discussing variability over time in sources of South Portuguese Zone turbidites.

When do we need pan-global freeze to explain ^(18)O-depleted zircons and rocks? [PDF]
Rocks with δ^(18)O values of less than 5‰ SMOW (Standard Mean Ocean Water) contain oxygen derived from ∼0‰ seawater or meteoric (rain or melted snow,

Possible Jurassic age for part of Rakaia Terrane: implications for tectonic development of the Torlesse accretionary prism [PDF]
Greywacke sandstone and argillite beds comprising Rakaia Terrane (Torlesse Complex) in mid Canterbury, South Island, New Zealand, are widely regarded as Late Triassic (Norian) in age based on the occurrence of Torlessia trace fossils, Monotis, and other ...

U-Pb isotopic ages of zircons from Precambrian rocks of South Greenland
Results of age determinations on zircons from samples of gneiss, granite, syenite and diorite from the Ketilidian mobile belt of South Greenland are presented. The lead isotopes were determined by a direct ionisation method. As three of the four zircon concentrates gave more or less discordant results, their interpretation is difficult.

U-Pb isotopic results for single shocked and polycrystalline zircons record 550-65.5-Ma ages for a K-T target site and 2700-1850-Ma ages for the Sudbury impact event [PDF]
The refractory mineral zircon develops distinct morphological features during shock metamorphism and retains these features under conditions that would anneal them in other minerals.

U-Pb zircon age of the pegmatoid of the Muong Lat complex
Muong Lat granitoid complex located in Thanh Hoa province. It is composed of two mica granite, aplite and pegmatoid. Rock forming minerals include mainly K-feldspar, quartz biotite and muscovite. Crystallization age of pegmatite in Muong Lat body is determined by U-Pb zircon LA-ICP-MS method.

Shoshonitic enclaves in the high Sr/Y Nyemo pluton, southern Tibet: Implications for Oligocene magma mixing and the onset of extension of the southern Lhasa terrane [PDF]
Post-collisional potassic and high Sr/Y magmatism in the Lhasa terrane provides critical constraints on the timing and mechanism of subduction of Indian lithosphere and its role in the uplift of the Tibetan Plateau.
