LSU Doctoral Dissertations
This dissertation uses fossil (ice core) and modern pollen samples collected throughout the central Andes to investigate the paleovegetational changes in the area as well as the modern dispersal and depositional characteristics of pollen in this region of South America. The results of the fossil pollen study on Mt. Sajama reveal a vegetation history that closely corresponds to the chemical and physical records already published from the mountain. Pollen becomes abundant after 15,000 B.P. and suggests the occurrence of two distinct phases between 15,000 and 12,000 B.P. (a short interstadial and the Deglacial Climatic Reversal). After 12,000 B.P., there is …
