Geological and geochemical data from the Canadian Arctic Islands. Part XII : descriptions and lithologs of Upper Paleozoic core / [by] P.B. Kabanov and K.E. Dewing. : M183-2/7569E-PDF
The inventory of Upper Paleozoic core , 415 m in total thickness, includes sandstone, limestone, dolostone, shale, chertstone, conglomerate, anhydrite, salt, and diabase. Measured cores mostly represent short sections not exceeding 18.5 m in thickness. Porosity was observed in 11 out of 52 cores, and mostly it is patches of low to moderate matrix porosity in sandstone. Oil impregnation was observed in five porous sandstones and carbanates. There are 20 occurrences of relatively thick (over 2 m) shale or shale-dominated intervals. Three gradational classes of shales are recognized: (1) dark gray or black laminated shales with a bioturbation index (BI) not exceeding 2; (2) dark gray shales with more intense bioturbation patterns (BI over 2) and commonly containing benthic fossils; and (3) mottled, commonly reddened shales with visually degraded coaly detritus. The first group, deposited in a dysoxic to anoxic setting, is the most interesting target for shale hydrocarbon exploration.
