Time Scales of Climate Change part of Cutting Edge:Rates and Time:Teaching Activities
This activity introduces students to the fact that climate change occurs at timescales of 1 year to 108 years and there are various drivers to explain these changes. It addresses how scientists detect these scales of climate change on the geologic record. Students, using what they learn, are also asked to evaluate the potential drivers of climate change since the Industrial Revolution.
Cyclostratigraphy and astrochronology exercise part of Cutting Edge:Rates and Time:Teaching Activities
Simple classroom activity to highlight how cyclostratigraphy and concepts of astronchronology can be used to refine age control in sedimentary rocks, estimate rates of processes, and for time control and correlation.
Simplified Carbonate Sequence Stratigraphy part of Cutting Edge:Sedimentary Geology:Activities
Sequence stratigraphy is jargon-laden and typically presented in an overly complicated manner which turns many students off. This lab is a simple and straightforward introduction to sequence stratigraphic interpretations of a carbonate platform using a combination of facies analysis, facies correlations, hand samples, thin sections, and is followed up by students reconstructing the platform profile at specific time intervals during sequence development to detect and interpret changes in platform morphology.
Delta environments and paleogeography part of Cutting Edge:Sedimentary Geology:Activities
One of the most basic and useful aspects of stratigraphy is reconstructing paleogeography using correlated stratigraphic columns. This lab introduces students to the reconstruction of deltaic paleoenvironments through three time slices using stratigraphic columns, facies analysis, bentonite marker beds, and paleoflow indicators (using rose diagrams). Construction of the paleogeographic maps teaches students to think in 3-dimensions and through time, and forces them to make educated interpretations based on limited data control.
Maya Elrick part of Workshop 2012:Essays
My research focusses on millennial-, orbital- and My-scale paleoclimate cycles in marine sedimentary rocks, so dealing with trying to determine absolute time and rates in sedimentary successions is essential for me. Because of this, I stress time in sedimentary successions in my classes (Earth History, Sedimentology-Stratigraphy, Carbonate Sedimentology).
