|---|---|
| Definitionskos:definition | Sandstone petrographic composition term indicating that detrital mode for clastic rock (Q-F-L) includes less than 75 percent quartz and the feldspar to lithic ratio is greater than 3 to 1. This corresponds to the arkose field of Folk (1968). For clastic rocks with little or no matrix and cement, rocks in this detrital mode composition category will also have quartz-feldspathic mineralogical composition. |
