Summary

Geologic mapping, characterization of geologic structures, and sampling for geochronology was completed in two areas of the northwestern Sangre de Cristo Mountains from 2011 through 2017. This data release provides the raw analytical data, metadata and sample information for 20 zircon U-Pb age analyses from laser ablation-inductively coupled plasma mass spectrometry (LA-ICPMS). The two areas include the Poncha Pass area where the entire 71/2’ Poncha Pass quadrangle and parts of five other quadrangles (Mount Ouray, Maysville, Salida West, Salida East, and Wellsville) were mapped at a scale of 1:24,000 (see Minor and others, 2019). The Deadman thrust fault is the second area, approximately 80 km southwest of the Poncha Pass area, and [...]

Purpose

The research common to both the Poncha Pass and Deadman areas involves documenting and understanding the evolution of continental crust and the geological processes involved with the inception, age, deformation, and growth of the Rio Grande rift. New U-Pb zircon geochronological data from the wide range of representative rock types provided by this data helps to fill gaps in understanding the geologic and tectonic framework of the northwestern Sangre de Cristo Mountains.
