Gazzi-Dickinson method
Videos
The Gazzi-Dickinson method is a point-counting technique used in geology to statistically measure the components of a sedimentary rock, chiefly sandstone. The main focus part of the technique is count
A sand grain that could be used for the Gazzi-Dickinson method. Scale box in millimeters, plane-polarized light on top, cross-polarized light on bottom. Landing on the large phenocryst of amphibole (center, clear in plane light, orange in cross-polarized light) would count as a mineral grain in the Gazzi-Dickinson method because it is sand-sized. Landing on the plagioclase-rich groundmass surrounding the grain would count as a volcanic lithic fragment. It would count as a volcanic rock fragment in the
