Exploration Activity: Petrography Analysis At Geysers Area (Lambert & Epstein, 1992)
|Exploration Activity Details|
|Exploration Technique||Petrography Analysis|
Rocks and minerals were visually identified in cuttings, and identifications were confirmed through examination of thin sections. X-ray powder diffraction was used to test the purity of some mineral separates. The chemical compositions of some metamorphic minerals were determined by electron microprobe.
