PLANT REMAINS AND RELATED SUBSTANCES IN THE PAST LACUSTRINE SEDIMENTS O F THE MT. RIISER-LARSEN
Abstract: Fragments of protonematoid moss plants remains, and empty shells seldom containing a plastid debris of epiphytic and free-living diatoms of Ach-nanthes and Pinniilnria were found in the laminated muddy sediments formed in the past lacustrine environment of Lake Richardson in the vicinity o...
