Finding FaultsHow the Burgeoning Walker Lane May Split the American West
By Mike Wolterbeek, Nevada Today, February 18, 2020

Excerpts: “California won’t fall into the ocean, but it could get nudged hundreds of miles offshore, making Nevada the new coastline of the continent, scientists at the Nevada Bureau of Mines and Geology at the University of Nevada, Reno hypothesize. They have combined decades of data and the latest technology to study the Walker Lane, an approximately 1000-kilometer-long (625 miles) corridor riddled with hundreds of earthquake faults.

Several researchers at the University are part of a group of scientists who are studying the massive system of relatively discontinuous faults that runs through western Nevada. It is known as the Walker Lane and in about 7-8 million years or so could become the new tectonic boundary between the North American and Pacific plates. The group at the University is relatively rare, as it includes expertise that analyzes fault zones at three different time scales from tens of millions of years (structural geology/tectonics) to the past approximately two million years (paleoseismology) to the present (geodesy). This combination of expertise is needed to understand the evolution of something potentially as grand as the Walker Lane.  In essence, the University team combines the most modern fieldwork techniques with the latest technologies such as satellites, LIDAR and computer simulations…”

“But it’s the combination of three science disciplines that illustrates the prominence of the Walker Lane – paleoseismology, geodesy and Faulds’ specialty of structural geology/tectonics. All three perspectives are crucial in analyzing something like the Walker Lane, because they provide three different timeframes with which to evaluate the evolution of the Walker Lane – from what’s happening now, to the past million years or so, and to the long-term (back-tracking tens of millions of years). We have all three disciplines in the College of Science at the University of Nevada, Reno…”

Geologic Map of the Granite Peak Quadrangle, Washoe County, Nevada

View, download, or purchase the Granite Peak Quadrangle map.

The Granite Peak 7.5-minute quadrangle is located immediately north of Reno, and abuts the Nevada-California state line in an area known as the ‘North Valleys’. The quadrangle includes the summits of Petersen Mountain and Granite Peak, and portions of Red Rock Valley and Cold Springs valley. The bedrock exposures in the quadrangle consist primarily of Cretaceous granitic rocks related to the Sierra Nevadan batholith. The granitic rocks include three distinct lithologies with relative ages constrained by clear crosscutting relationships. Miocene to Pliocene clastic and fluvio-lacustrine sediments are deposited in a shallow basin west of Freds Mountain in the easternmost part of the quadrangle. On the western flank of Petersen Mountain, west-dipping Oligocene ash-flow tuff deposits nonconformably overlie Cretaceous granite. Quaternary sediments largely consist of alluvial fans and several large landslide deposits (up to 2.7 sq. km.).

The quadrangle is bisected by the Petersen Mountain fault zone. The fault zone consists of two subparallel traces (western and eastern) that extend from Cold Springs valley in the south to Seven Lakes Mountain in the north. The western trace of the fault strikes generally north-south along the eastern range front of Petersen Mountain, dips steeply east, and locally displaces surficial deposits as young as Holocene. The eastern trace consists of several north-south striking strands that displace surficial deposits as young as late Pleistocene and locally forms a narrow graben infilled by faulted fanglomerate material. Fault surfaces on the eastern trace have subhorizontal slickenlines demonstrating a history of dextral-oblique motion. Long-term late Cenozoic normal displacement across the western trace is demonstrated by the high relief of the Petersen Mountain range front (>500 m) as well as the accumulation of Miocene-Pliocene sediments to the east that were likely deposited into a basin controlled by early displacement along the fault. This is in contrast to the eastern strand, which has been active since at least the middle Pleistocene but for much of its length does not bound basins with significant accumulations of late Cenozoic deposits. These map relationships suggest the Petersen Mountain fault zone initially developed as a Basin and Range extensional structure with displacement primarily along the western fault trace, and has evolved into a Walker Lane structure with dextral-oblique motion focused on the eastern trace.
