Olivine Infrared Spectra (generally 4000 - 3000 cm^-1)

Data files and images of OH in olivine

• Forsterite 1006 image; 6K GRR 1006, Forsterite from a kimberlite on the Monastery Farm, Winburg, South Africa. Image normalized to 10 mm thickness. This is a comparitively high OH-content forsterite. Data files: a, 30K; b, 32K; c, 29K;
• Forsterite 1283 image; 11K GRR 1283, Forsterite from the basalt flow at San Carlos, Arizona. This sample has been in annealed under water in the laboratory to increase its water content. Sample SC7#3 of Steve Mackwell. Image nomralized to 10 mm thickness. Data files: a, 33K; b, 33K; c, 33K;
• Forsterite 999 image; 11K GRR 999, Forsterite from the hydrothermal veins on Zabargad Island, Egypt. Image normalized to 10 mm thickness. Data files: a, 24K; b, 25K; c, 23K;
• Forsterite 1012 image; 5K GRR 1012, Forsterite from the Kimberley Mine, Kimberley, South Africa. Image normalized to 1.0 mm thickness. Data files: a, 49K; b, 49K; c, 49K;
• Forsterite 1695 image; 5K GRR 999, Forsterite from Black Rock Summit, Nevada, USA. Image normalized to 10 mm thickness. Data files: a, 46K; b, 49K; c, 46K;
• Forsterite KLV23 image; 5K KLV-23, Forsterite from the Kaalvallei kimberlite, South Africa. Image normalized to 1.0 mm thickness. Data files: a, 19K; b, 19K; c, 19K;
• Forsterite 1390.  This brown olivine sample from Buell Park, Arizona, contains clinohumite layers as evidenced by both TEM and IR studies.
