Journal ArticleDOI
Improved 206Pb/238U microprobe geochronology by the monitoring of a trace-element-related matrix effect; SHRIMP, ID-TIMS, ELA-ICP-MS and oxygen isotope documentation for a series of zircon standards

TL;DR: In this article, the authors investigated correlations between the age offsets and P, Sm and Nd abundances in the zircons, and concluded that the presence of Nd is not the primary cause of the apparent matrix effect.
Journal ArticleDOI
U‐Pb geochronology of zircons from lunar breccia 73217 using a sensitive high mass‐resolution ion microprobe
TL;DR: In this paper, the age of four zircons from thin-sections of one highland breccia, 73217, using the recently constructed ion microprobe SHRIMP was determined.
Journal ArticleDOI

TL;DR: The 2008 BHIVA Guidelines have been updated to incorporate all the new relevant information since the last iteration and all the peer-reviewed publications and important, potentially treatment-changing abstracts from the last 2 years have been reviewed.
Journal ArticleDOI
Zircon U-Pb ages for the Early Cambrian time-scale
TL;DR: In this paper, single zircons from two Early Cambrian volcanic horizons have been analyzed using the SHRIMP ion microprobe, revealing the presence of both detrital or xenocrystic grains as well as areas within grains that have lost radiogenic Pb.
