21. Northern Resources Development CAE Feb 21 ‘06 Ministry of Energy and Mines Resource Development And Geoscience Branch Bowser-Sustut Current Knowledge Other research – Provenance and age constraints from Isotopic Systems (V. McNicoll) Combined cumulative probability plots have youngest peak at the depositional age of the rock determined paleontologically. To date >750 zircon grains from 14 samples analyzed. The consistency with which the youngest peak is on the depositional age of the rock provides cautious optimism that we can use this method to determine the age of sections where fossils are lacking – target is unit boundaries. Typical Bowser Lake Gp detrital zircons on SHRIMP mount APPROACH – collect sandstone from strata whose age is well constrained paleontologically, and from diverse geography, map units, and ages. U-Pb SHRIMP analyses of detrital zircons provide a maximum age.

From field season - significantly refined distribution of map units in the southern basin; refinement of unit characteristics; completion of collection of sample suites for thematic studies. From ongoing work – major progress on a number of studies – thermal maturity, organic petrology, petroleum systems, thermal history (AFTT, paleomagnetism), provenance, paleontology, lithogeochemistry, seismic tomography, structural analysis.
