Synopsis The Guadalupe Canyon fault is a short, east-west-trending fault in the southeastern part of the Guadalupe Mountains, just north of the U.S.-Mexico border and just west of the Arizona-New Mexico border. The fault mainly cuts bedrock, but along about 3 km of its length, the fault forms 10- to 20-m-high scarps on Pliocene to lower Quaternary alluvium. There are no meaningful constraints on the age of youngest movement on this fault.

Name comments Initially mapped by Hayes (1982 #2115) but not interpreted as cutting Quaternary alluvium. Menges and Pearthree (1983 #2073) and Machette and others (1986 #1033) recognized it as a possible Quaternary fault based on a fault scarp formed on a thin veneer of Pliocene to lower Quaternary alluvium.

Compiled at 1:24,000 scale.

Comments: Mapped by Hayes (1982 #2115) at 1:62,500 scale and field-checked on a reconnaissance basis and compiled at 1:250,000 scale by Machette and others (1986 #1033). Compiled fault trace from 1:24,000-scale mapping of Skotnicki (2002 #7361), though he did not show it as cutting Quaternary alluvium.

Geologic setting For most of its length, this is an intra-bedrock fault within the Guadalupe Mountains, displacing mainly Cretaceous and Oligocene rocks. An upper Pliocene to lower Quaternary basalt is in contact with the fault and may be faulted. The east-west orientation of the fault is unusual among Quaternary faults of this region.

Length (km) 5 km.
Average strike N85°E
Sense of movement Normal

Comments: Normal fault as mapped in bedrock by Hayes (1982 #2115).

Dip Direction S
Paleoseismology studies

Geomorphic expression The fault forms 10- to 20-m-high scarps on the remnants of Pliocene to lower Quaternary alluvial fans.

Age of faulted surficial deposits Early Pleistocene to Pliocene. The estimated age of faulted alluvium is based on geomorphic surface characteristics and topographic position in the landscape.
Historic earthquake
Most recent prehistoric deformation undifferentiated Quaternary (<1.6 Ma)

Comments: Age of youngest faulted deposits is Pliocene to early Pleistocene. There is no meaningful minimum constraint on the age of youngest faulting event. Given the uncertainty in the age estimate of the faulted alluvial deposits, there may have been no Quaternary movement on this fault.

Recurrence interval
Slip-rate category Less than 0.2 mm/yr

Comments: A low slip rate is inferred based on less than 20 m of displacement during the past 1 m.y.
