Synthetic Pyroxene Spectral Database

To download an excel spreadsheet with the digital spectral data, please click on the plots in each section below. Spectra for Ca-bearing pyroxenes will be provided as soon as analyses are completed. The synthetic pyroxenes were provided for this study by Don Lindsley, Al Turnock and Darby Dyar. Details regarding sample synthesis procedures can be found in:
