Detailed discussion of the relationship between maceral composition and gas content. Vitrinite reflectance controls maceral composition and gas content. Gas content varies in lateral extension and vertical sequences. Gas content of coals with Ro,max between 1.0% and 2.5% is mainly controlled by preservation conditions.
