The African Humid Period (AHP) resulted in more humid conditions across Northern and Eastern Africa from 15 to 5 thousand years ago (ka). This wetter climate affected flora, fauna and the Homo sapiens living in East Africa. The lack of terrestrial paleoenvironmental reconstructions is a problem in East Africa, especially during the AHP, where most are done utilizing lacustrine or marine proxies. In the case of Gona, Ethiopia, terrestrial proxies are desired due to the rich archaeological and fossil concentrations that occur in the area. Paleosols provide more direct, localized reconstructions that provide context for these finds. This study utilizes …

Using X-Ray Fluorescence To Analyze Fire Impacted Soil And Vegetation Composition, Dylan Darter
Kansas State University Undergraduate Research Conference
In our lab, I am using an X-ray fluorescence (XRF) to measure the concentrations of metals in sediments from subalpine lakes. Our goal is to measure the biogeochemical consequences of wildfires over the last 2000 years. This study looks at the elemental composition of different lake cores, and vegetation samples from areas of the “Big Burn” fire of 1910. This fire burned across several states in the Rocky Mountain region. With our XRF data we are able to see how the fire impacted the soils and how long after the fire proper soil composition can occur. This study can be …
