Organic geochemical characterization of a Miocene core sample from Haughton impact structure, Devon Island, Nunavut, Canadian High Arctic

Extremely well preserved sedimentary deposits in the Haughton impact structure (HIS) provide a unique record of the post-impact Miocene lacustrine depositional environment. Detailed organic geochemical characterization of a hydrocarbon-impregnated band found in a core from the crater-lake sedimentary infill reveals a complex source history for the hydrocarbons. These include contributions from eroded pre- and post-impact formations together …
