Regional Geology

This geological map and associated information on rock units at or nearby to the coordinates given for this locality is based on relatively small scale geological maps provided by various national Geological Surveys. This does not necessarily represent the complete geology at this locality but it gives a background for the region in which it is found.

Chattian - Rupelian
23.03 - 33.9 Ma

ID: 2862313
Lower-upper middle Tertiary basaltic andesites and andesites of the Mogollon Group

Age: Oligocene (23.03 - 33.9 Ma)

Stratigraphic Name: Mogollon Group

Description: Includes La Jara Peak Basaltic Andesite, Uvas Basaltic Andesite, basaltic andesites of Poverty Creek and Twin Peaks, Squirrel Springs Canyon Andesite, Razorback Basalt, Bear Springs Basalt, flows of Gila Flat, Salt Creek Formation, Middle Mountain Formation, and the Alum Mountain Group. Pre-Amalia-Tuff lavas in the Questa caldera are dominantly silicic andesites and dacites; elsewhere silicic lavas are a minor component of Tual.

23.03 - 33.9 Ma

ID: 3274559
Tuff of Tetilla Peak

Age: Oligocene (23.03 - 33.9 Ma)

Description: Quartz-rich light-colored weakly welded rhyolitic ash-flow tuff (73–75 percent SiO2) containing abundant small volcanic fragments. Phenocryst content 10–30 percent; mainly quartz, sanidine, plagioclase, and sparse chloritized biotite. Lithic fragments mostly andesite and quartz- bearing rhyolite; where the tuff is altered, lithic fragments are main indicator of original pyroclastic character. Unit ranges from light gray to buff in northeastern part of area, to dark-gray dense rocks of obscure texture where baked and otherwise altered by granitic intrusions within the caldera. Tuff of Tetilla Peak is closely associated in areal and stratigraphic position with large rhyolite flow-dome complexes (Trc); the tuff probably represents pyroclastic eruptions associated with emplacement of the rhyolite flows. In places several ash-flow units, each 10–30 m thick, are separated by thin interbeds of rhyolitic ash-fall tuff or reworked tuffaceous sedimentary rocks equivalent to the volcanic sedimentary unit (Tvs). Within the Questa caldera, tuff of Tetilla Peak is locally difficult to distinguish from the lithic-rich lower part of the Amalia Tuff (Trtl). Tuff of Tetilla Peak is as much as 300 m thick; substantial local thickness variations are due to pre-eruption topography and in places to subsequent structural complications
