Cambrian stratigraphy and paleontology
chercheur principal: Pratt, Brian R.
Année(s) de permis: 2019
Résumé: Sedimentary rocks of Cambrian age (~500 million years old) are the oldest Phanerozoic strata in the Mackenzie River valley region and record the spread of a shallow sea over much older strata. The approximate age of these rocks is known via trilobite fossils based on reconnaissance collections made in the 1960s and 2010s. The purpose of the project is to make more closely spaced fossil collections...

Cambrian stratigraphy
chercheur principal: Pratt, Brian R.
Année(s) de permis: 2012 2002 2000 1998
Résumé: The principal investigator has been working off and on for many years on the stratigraphy and paleontology of Cambrian strata of the Mackenzie Mountains. This is a critical region of North America because the record of sedimentation on the flank of the continent as it was over half a billion years ago is particularly extensive with little interruption. At the section of interest the lower part of ...

Upper Cambrian Trilobite Biostratigraphy of the Cass Fiord Formation, Ellesmere Island
chercheur principal: Pratt, Brian R.
Année(s) de permis: 1995 1993
Résumé: The researcher will study trilobite fossil communities that exsisted in the Cambrian Period. Study of these fossils will help in more precisely dating the rocks laid down by this sea. The researcher will also prepare a biostratigraphic zonation....
