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 ...
متن کاملDating 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...
متن کاملSmall-volume U–Pb zircon geochronology by laser ablation-multicollector-ICP-MS
U–Pb zircon geochronology is hampered by problems acquiring meaningful geologic ages on zoned grains that retain isotope signatures from multiple growth or thermal events. We present a new method using laser ablation-multicollector-inductively coupled plasma-mass spectrometry to overcome complications asso ciated with intricately zoned zircon crystals through in situ sampling of zircon volumes...

متن کاملDETRITAL ZIRCON U/Pb AGE DETERMINATION: UNDERSTANDING THE PROVENANCE OF THE LATE- CRETACEOUS SHUMAGIN FORMATION, ALASKA
The Chugach-Prince William (CPW) terrane is an Upper Cretaceous to Eocene accretionary complex exposed for ~2200 km in southern Alaska, extending from Baranof Island in the east to Sanak Island in the west. One of the thickest subduction-related accretionary complexes in the world, the CPW terrane is composed of deep-water flysch and associated volcanic rocks and is intruded by near-trench plut...
