Microscopic thin-section analysis of area-volume relations is presented on a simplified granulometric basis. In thin-section, volumetric composition is obtained by point counting, whereas in grain slides, granulometric composition is obtained by ribbon sampling. Inherent errors in methods based on ribbon sampling of thin sections or point counting of grain slides are made evident.
