The geological history of the Canadian Shield is difficult to constrain because the sedimentary record is missing in those areas where Precambrian basement is...
We present a multi-chronometric approach for reconstructing deep-time thermal histories using southern Baffin Island as a case study. This continuous thermal...
Apatite fission track (AFT) and elemental data are presented for a Permian and Devonian sample from northern Yukon in support of a journal paper (submitted to...
Cratons are generally considered to comprise lithosphere that has remained tectonically quiescent for billions of years. Direct evidence for stability is...
The Geo-mapping for Energy and Minerals (GEM) program (2008-2020) of the Geological Survey of Canada made important contributions to the understanding of...
Central tenets of the snowball Earth hypothesis are that mantle upwelling and widespread igneous magmatism during equatorial supercontinent breakup led to...
Knowledge of the kinetic behavior of He in apatite and other U- and Th-bearing minerals comes largely from detailed step-heating experiments, yet such...
Old slowly-cooled apatites often yield dispersed (U-Th)/He ages for a variety of reasons, some well understood and some not. Analytical protocols like careful...
