Figure 3. Organic petrography images of Huron samples. (A) Sample OH-3 1090–1090.3 ft showing groundmass regions of bituminite (amorphous organic matter) outlined in red. Incident white light under oil immersion. (B) Same field as (A) under epifluorescence. (C) Sample KTY-66 showing groundmass regions of solid bitumen with gray reflecting surface (white arrows) and euhedral carbonate (red arrows). Incident white light under oil immersion. (D) Same field as (C) under epifluorescence. (E) Sample Bailer 3713.25–3715 ft showing Tasmanites (red arrows). Incident white light under oil immersion. (F) Same field as (E) under epifluorescence.
