- Abstract
- New Nd isotopic data of zircon grains from dikes and spatially associated, penecontemporaneous tuffs within the Latir volcanic field (NM) and Mount Princeton (CO) do not show an isotopic connection between the dikes and tuffs. I hypothesize that these inconclusive results are from inheritance of Precambrian zircons within the samples. U-Pb geochronology data of the Questa ring dike sample supports this hypothesis because it is demonstrably older than previously dated samples. Future research should date the samples using zircon U-Pb geochronologic methods alongside the Nd analysis to ensure that the samples are not contaminated with inherited zircons.
