Minimizing the effects of Pb loss in detrital and igneous U–Pb zircon geochronology by CA-LA-ICP-MS [PDF]

open access: yesGeochronology
Detrital zircon geochronology by laser ablation–inductively coupled plasma–mass spectrometry (LA-ICP-MS) is a widely used tool for determining maximum depositional ages and sediment provenance, as well as reconstructing sediment routing pathways ...

Discordance dating: A new approach for dating alteration events [PDF]

open access: yesGeochronology
Zircon is the premier geochronometer used to date igneous and metamorphic processes, constrain sediment provenance models, and monitor key events in Earth history such as the growth of continents and the evolution of the biosphere.

Chemical abrasion applied to LA-ICP-MS U-Pb zircon geochronology [PDF]

open access: yes, 2014
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.

Modeling apparent Pb loss in zircon U–Pb geochronology [PDF]

open access: yesGeochronology
The loss of radiogenic Pb from zircon is known to be a major factor that can cause inaccuracy in the U–Pb geochronological system; hence, there is a need to better characterize the distribution of Pb loss in natural samples.

U-Pb zircon age of the pegmatoid of the Muong Lat complex

open access: yesScience and Technology Development Journal - Natural Sciences, 2019
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.
