Abstract

Surface sediments were sampled from Prado Lake (7 samples) and Salty Lake (5 samples) in southern Western Australia for palynological analyses. Light microscopy was utilized in examining the samples for dispersed organic matter (palynofacies) and organic-walled microfossils (palynomorphs). The most abundant dispersed organic components were comminuted and structured phytoclasts; amorphous organic matter was also common. Pollen and spore were more commonly preserved in the Prado Lake samples, as opposed to the Salty Lake samples. An overview of the types of palynomorphs preserved in the samples suggests vegetation comprising mainly aridloving floras. Statistical analysis of the data yields useful information about the paleoenvironmental conditions and overall lake history.

Biography

Brittany is a senior in the Geological Science and Engineering Department, with a minor in Nuclear Engineering. Aside from undergraduate research in palynology, she is also active in Student Union Board as the Promotions Director for the Concert Committee and is a board operator for the KMST station on campus. After graduation, she will be continuing on with geology into graduate school.
