Cambrian stratigraphy and paleontology
Principal Investigator: Pratt, Brian R.
Licensed Year(s): 2019
Summary: 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
Principal Investigator: Pratt, Brian R.
Licensed Year(s): 2012 2002 2000 1998
Summary: 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 ...

Cambrian sedimentology and paleontology
Principal Investigator: Pratt, Brian R.
Licensed Year(s): 1995 1993
Summary: The Cambrian period is an interval of geologic time that is poorly known in arctic Canada. Previous studies have been very basic and almost no fossils have been recovered. Sections of sedimentary rock will be measured in detail, with attention focused on the structure of the sediments as well as the presence of fossils. A map will then be constructed showing the layers in which fossils occur. ...
