Representative photomicrographs of maceral of the Samfarinda coals. (a, b) Alginite associated with humodetrinite (a) in reflected white light and (b) fluorescence mode in same view as (a), Sample 7. (c, d) Suberinite associated with humodetrinite in coal, (c) reflected white light and (d) in fluorescence mode in same view as (c), Sample 10. (e) Funginite associated with humodetrinite groundmass in coal, (f) fluorescence mode in same view as (e), Sample 9. (g) Suberinite associated with humodetrinite groundmass in coal, Sample 9. (h) Same as for Figure (g), but in fluorescence mode. Hu: humodetrinite, Al: alginite, and Su: suberinite.
