Open-File Report 14-6
Preliminary geologic map of Heath Canyon, central Grant Range, Nye County, Nevada, by Sean P. Long, 2014
New 1:24,000-scale mapping across the full width of the central Grant Range, in a transect-style map located east of the Grant Canyon and Bacon Flat oil fields in Railroad Valley, provides valuable context for relating the structural style and geometry within the range to the subsurface structure of the oil fields. Sedimentary rocks between Cambrian and Pennsylvanian in age, and Eocene to Oligocene sedimentary and volcanic rocks, are exposed in the map area. Cambrian and Ordovician rocks have been metamorphosed to greenschist facies and experienced penetrative ductile deformation, likely during the Cretaceous. Two separate sets of normal faults deform the section, including an older set of down-to-the-west detachment faults that eliminate stratigraphy, and formed at low angles to bedding, and a younger set of high-angle, cross-cutting normal faults, including a range-bounding fault with multiple Holocene surface ruptures. Several detachment faults cut Oligocene volcanic rocks, providing a maximum age bound for the older episode of extension.
This publication was prepared as part of the STATEMAP component of the National Cooperative Geologic Mapping Program in cooperation with the U.S. Geological Survey.

Open-File Report 13-10 (second edition)
Preliminary geologic map of the central Lake Range, southern Fox Range, and northern Terraced Hills, Emerson Pass geothermal area, Washoe County, Nevada, by Ryan B. Anderson, James E. Faulds, and Gregory M. Dering, 2014
Detailed geologic mapping and stratigraphic-structural analyses have elucidated the kinematics, stress state, and structural controls of a “blind” geothermal system in Emerson Pass on the Pyramid Lake Paiute Tribe Reservation, western Nevada. The Emerson Pass area resides near the boundary of the Basin and Range and Walker Lane provinces of northwestern Nevada, at the northeast end of Pyramid Lake. Strata of the surrounding Fox Range, Lake Range, and Terraced Hills are comprised of late Miocene to Pliocene sedimentary rocks and the middle Miocene Pyramid sequence volcanic rocks, all overlying Cretaceous intrusions and Triassic to Jurassic metasedimentary rocks.
The active geothermal system is expressed as a 2-m shallow temperature thermal anomaly (maximum ∼60°C) that lies at the western edge of a broad left step at the northeast end of Pyramid Lake between the north- to north-northeast-striking, west-dipping, Fox and Lake Range normal faults. The 2-m temperature surveys have defined a north-south elongate thermal anomaly that resides on a north- to north-northeast-striking normal fault. Additionally, travertine mounds, chalcedonic silica veins, and silica-cemented Pleistocene lacustrine gravels in Emerson Pass indicate a robust geothermal system active at the surface in the recent past, likely the early Holocene. Structural complexity and spatial heterogeneities of the strain and stress field have developed in the step-over region, but kinematic data suggest a west-northwest-trending (∼280° azimuth) extension direction. The geothermal system is likely hosted in Emerson Pass as a result of enhanced permeability generated by the intersection of two oppositely dipping, southward- terminating north- to north-northwest-striking (Fox Range fault) and north-northeast-striking normal faults.
This publication was prepared with support from the U.S. Department of Energy. We thank the Pyramid Lake Paiute Reservation for access to tribal lands and logistical support throughout the project.
Geochronologic data (several 40Ar/39Ar dates) were added to this second edition.

Congratulations are in order for three of our current and recent graduate students who won “gold, silver, and bronze” (clean sweep) in the 2014 Student Geologic Map Competition at the annual meeting of the Geological Society of America in Vancouver, BC, today (October 21, 2014).
Chad Carlson: 1st place for his Geologic Map of the Terrill Mountains, western Nevada. Ph.D. student (Advisor-Jim Faulds)
Russell DiFiori: 2nd place for his Geologic Map of the Eureka Mining District, eastern Nevada. M.S. completed-May 2014 (Advisor-Sean Long)
Joel Edwards: 3rd place for his Geologic Map of Neal Hot Springs, eastern Oregon. M.S. completed-May 2013 (Advisor-Jim Faulds)
All three worked incredibly hard and dedicated many months to generating some very detailed and beautiful maps of some very complex geology. These maps will stand as enormous contributions for many years to come. Please join me in congratulating three very talented individuals.
Our Cartographic/GIS staff also deserve kudos for helping with the layout and providing technical assistance on the maps.
