Geologic units containing quartz latite
A volcanic rock defined in the QAPF diagram as having Q/(Q+A+P) between 5 and 20% and P/(P+A) between 35 and 65%...
- Intra-ash flow quartz latitic lavas (Phanerozoic | Cenozoic | Tertiary)
- Dacite to rhyolite (or rhodacite) ignimbrites; Eocene rhyodacitic cauldron complex; east-central Idaho, central Challis volcanic field (Eocene)
- Eocene mixed silicic and basaltic volcanic ejecta, flows and reworked debris.
- Rhyolite, quartz latite, and latite ignimbrites and flows; Miocene felsic volcanics; Owyhee Plateau; (Miocene)
- Miocene silicic flows, tuffs; most common in southwestern Idaho.
- Silurian Rocky Mountain Quartz Latite (Silurian)
- Silurian Rocky Mountain Quartz Latite
- Volcanic sandstone, felsic ash-flow tuffs, rhyolite, and rhyodacite flows (Middle Jurassic to Early Cretaceous)
- VOLCANIC SANDSTONE, FELSIC ASH-FLOW TUFFS, RHYOLITE, AND RHYODACITE FLOWS (Upper? Jurassic)-Pony Trail Group of Cortez Mountains, Eureka County
- Eocene-Oligocene volcanic rocks (Eocene-Oligocene)
- Predominantly light-green, bedded andesite breccia with interbedded andesite and basalt flows, mudflows, and tuff beds; becomes more tuffaceous near top of unit. Includes tuffaceous and arkosic sandstone, shale, and carbonaceous shale beds in central and southern Cascade Mountians. Rhyodacite and quartz latite flows in northwestern Ferry County.
- Dacite and quartz latite intrusive and extrusive igneous rocks (Phanerozoic | Cenozoic | Tertiary | Eocene)
- DACITE AND QUARTZ LATITE INTRUSIVE AND EXTRUSIVE IGNEOUS ROCKS (AGE ABOUT 44 Ma)--Light-gray porphyritic rock.
