Origins of Mafic Enclaves in the Dinkey Creek Pluton, Central Sierra Nevada Batholith, California part of Cutting Edge:Petrology:Teaching Examples
In this lab exercise, students use and substantial spreadsheet of major, minor and trace element data compiled from studies of the Dinkey Creek pluton (Sierra Nevada batholith) and its microgranular mafic enclaves. The use of the Excel Add-in Petroplot is a must for this exercise to save time. The Petroplot Add-in and its instructions can be found at the following web site: Petroplot Add-in

Batch and Rayleigh Decarbonation Modeling of d13C part of Cutting Edge:Petrology:Teaching Examples
This is an Excel spreadsheet and graph that illustrates standard "batch" and Rayleigh decarbonation models and how they can be used to detect fluid infiltration during metamorphism of carbonates. It makes a good lecture demonstration, but with a few modifications can be turned into a laboratory exercise. Key variables are "hotlinked" directly into the batch and Rayleigh models so students can adjust them to get a feel for the influence of different model parameters. The included carbon isotope data are from marbles in the Jervois region, central Australia (Cartwright et al., 1997). Oxygen isotope data are also included in the spreadsheet.
