Figure F20. Empirically deduced tectono-genetic provenance of sandstones according to their framework composition, displayed in terms of quartz (Q), feldspar (F), and lithoclast (L) grains (Dickinson, 1985). The framework composition of the lithic arenites from Unit II plots in the "Undissected arc" field.
