Zircon U/Pb ages for gniess from Qianshan, Anhui

Chinese Science Bulletin, 2000
Zircon U/Pb ages were measured for Qianshan gneiss at the ultrahigh pressure metamorphic (UHPM) complex in the Southern Dabie Terrain (SDT). According to morphology, Th and U contents of eight fractions of zircon and data distribution on the discordia, it is indicated that they should be treated as metamorphic overgrowth mixing zircons, in which the ...

Extensional faulting on Tinos island, Aegean sea, Greece: How many detachments? [PDF]

, 2007
Zircon and apatite fission track (ZFT and AFT) and (U-Th)/He, 40Ar/39Ar hornblende, and U-Pb zircon ages from the granites of Tinos Island in the Aegean Sea, Greece, suggest, together with published ZFT data, that there are three extensional detachments ...

New U-Pb zircon age and petrogenesis of the plagiogranite, Troodos ophiolite, Cyprus [PDF]

Lithos, 2020
Abstract The Troodos ophiolite is a classic and is one of the most complete and best-studied ophiolites on Earth. However, there are few studies on the geochronology of the plagiogranite in the Troodos ophiolite. With the advancement of zircon U-Pb in situ dating method developed in recent decades, it is necessary to revisit the age of the ...

Evaluating the construction and evolution of upper crustal magma reservoirs with coupled U/Pb zircon geochronology and thermal modeling:A case study from the Mt. Capanne pluton (Elba, Italy) [PDF]

, 2015
Evaluating mechanisms and rates for magma transport and emplacement in the upper crust is important in order to predict the thermal and rheological state of the crust, and understand the relationship between plutonism and volcanism. U–Pb geochronology on

High precision U–Pb zircon ages for Mesozoic igneous rocks from Hong Kong [PDF]

Journal of Asian Earth Sciences, 2012
Abstract Sixteen new high precision U–Pb zircon ages are reported from Jurassic and Early Cretaceous silicic volcanic and plutonic rocks of Hong Kong. When combined with the existing age dataset, the new ages constrain more tightly the timing of major periods of volcanism and plutonism at 162.6 ± 4.5 Ma, 146.7 ± 1.1 Ma, 143.0 ± 1.0 Ma and 140.8 ± 0.6
