Picture of Sandstone from the Chinle Formation at Lee’s Ferry. (Studied March-April 2013)
This past week I have started working on my analysis of the changes in chemical composition throughout the different layers that were sampled in the Chinle. The picture above exemplifies some of the unexpected material that was found in the layers. I was expecting to find ash in all the samples collected and they appear the same in hand sample, but look completely different under the microscope. I am excited to present the full results at the end of the semester.
