| Preferred Labelskos:prefLabel | lithic arkosic detrital mode |

| Definitionskos:definition | Sandstone petrographic composition term indicating that detrital mode for clastic rock (Q-F-L) includes less than 75 percent quartz and the ratio of lithic fragments to feldspar is between 1:1 and 1:3. This corresponds to the lithic arkose field of Folk (1968), the 75 percent quartz boundary is chosen to be consistent with quartzsose composition as defined in the mineralogic compostion terms vocabulary. Because of the abundance of lithic fragments for which the mineralogic composition is not specified, and the presence of undiscernible matrix and cement that are not incuded in the detrital mode, corresondence with the mineralogical composition terms is very approximate. |
