The level of organic maturation, thermal history and petroleum source potential of Phanerozoic strata in northern Yukon and northwestern District of Mackenzie have been investigated by measurement of vitrinite (% Rorand) and graptolite (% Romax) reflectance, conodont alteration index (CAI) and Rock-Eval pyrolysis.
