Combined Zircon/Apatite U-Pb and Fission-Track Dating by LA-ICP-MS and Its Geological Applications: An Example from the Egyptian Younger Granites

Dating of Precambrian Metasedimentary Rocks and Timing of their Metamorphism in the Soursat Metamorphic Complex (NW IRAN): Using LA–ICP-MS, U–Pb Dating of Zircon and Monazite

Soursat Metamorphic Complex (SMC) in west of Takab city is one of the polyphase metamorphic terrenes in northern Sanandaj-Sirjan metamorphic belt of Iran. The SMC composed mainly of metasedimentary rocks associated with granitic intrusions. Based on metamorphic rocks, two metamorphic phases could be separate in the complex. M1 is representative of regional metamorphisms which varies from greens...

Chemical Abrasion Applied to LA-ICP-MS U–Pb Zircon Geochronology

Zircon (ZrSiO4) is the most commonly used mineral in U–Pb geochronology. Although it has proven to be a robust chronometer, it can suffer from Pb-loss or elevated common Pb, both of which impede precision and accuracy of age determinations. Chemical abrasion of zircon involves thermal annealing followed by relatively low temperature partial dissolution in HF acid. It was specifically developed ...

In situ U-Pb Dating Combined with SEM Imaging on Zircon — An Analytical Bond for Effective Geological Recontructions

U-Pb Zircon and Titanite Dating in Support of British Columbia Geological Survey Regional Mapping Studies

In this paper we report U-Pb zircon and titanite data and interpreted ages for sixteen rocks (Figure 1) sampled in support of regional mapping projects conducted by the British Columbia Geological Survey Branch during the midto late-1990s. Each sample is reported with geological context, interpretation of U-Pb data and significance of the date. The U-Pb results are also displayed on standard co...
