Organic Type and Colour, and Hydrocarbon Potential: Offshore Eastern Canada: Abstract
Diverse views on the meaning of the term kerogen highlight the general absence of a standard terminology in visual studies on dispersed organic matter. At present there is no objective, purely morphological classification of organic material observed in transmitted light. Thus the terms amorphogen, phyrogen, hylogen and melanogen have been proposed for the four types recognized in our studies. Over 250 000 m of sediments from 75 wells drilled on the Scotian Shelf, Grand Banks and Labrador Shelf have been examined for organic type and colour. Organic type is closely related to the age of sediments, geographic location and depositional environments; amorphogen being most common in marine strata and hylogen in nonmarine sediments. In most wells examined the combination of organic type and colour indicates poor source rock potential for hydrocarbons. Exceptions are the Labrador Shelf and locally on the Scotian Shelf and Grand Banks, where the organic matter may reach maturity.
