Feldspar Mineral Chemistry Using the FCAEM Remotely Operable Electron Probe Micro-Analyzer. part of Mineralogy:Activities
Sven Holbik and Rosemary Hickey-Vargas, Florida International University
This lab uses the remote operation of an Electron Probe Micro-Analysis (EPMA) available through the Florida Center for Analytical Electron Microscopy (FCAEM; https://fcaem.fiu.edu/), at Florida International University, Miami, to explore feldspar mineral chemistry. This lab explores detailed mineral chemistry, data normalization, and plotting compositional ranges on ternary diagrams suitable as an introductory assignment in a Mineralogy, Earth Materials, or Petrology course. This instructor-led interactive demonstration of remote Electron Microprobe use introduces students to microprobe analysis, x-ray analytical techniques, standardization, image analysis, normalization, mineral formulas and composition. The instructor can acquire images (optional) of samples containing feldspar (provided by FCAEM or instructor's samples) then select multiple points for analysis. This activity captivates student's attention and provides a hands-on instrument-led approach to introducing undergraduate students to chemical analysis and vital concepts in mineralogy and petrology.
