Enhanced diffusion of Uranium and Thorium linked to crystal plasticity in zircon
Geochemical Transactions, 2006 The effects of crystal-plasticity on the U-Th-Pb system in zircon is studied by quantitative microstructural and microchemical analysis of a large zircon grain collected from pyroxenite of the Lewisian Complex, Scotland. Electron backscatter diffraction (

Classifying Detrital Zircon U-Pb Age Distributions Using Automated Machine Learning
Applied Computing and GeosciencesThe prodigious use of detrital zircon U-Pb geochronology for provenance studies in recent decades has led many researchers to amass extensive datasets (>100,000 dates). When displayed as age distributions, individual samples are traditionally compared using visual inspection and statistical methods, which can become time-consuming and challenging when ...

New U-Pb zircon ages of El Baúl Massif, Cojedes State, Venezuela
Revista Técnica de la Facultad de Ingeniería, 2009 El Baúl massif (Cojedes State, Venezuela) has been studied since 1858, especially as an important target for oil companies since it is a structural high that has played an important role in the evolution of the oil bearing Barinas-Apure and Eastern Venezuela sedimentary basins.
