Topic: Adventures in Nevada Oil and Geothermal Exploration,
some answers to geologic questions with examples from White River Valley, Lake Valley, Beowawe and Wabuska

Abstract: White River Valley, in Nye County Nevada, has no oil production as of this date; however, there have been numerous good oil shows, and coupled with the presence of good source rocks and reservoir rocks, it is only a matter of time before oil production is established. The southern half of white river valley is a Tertiary graben with Paleozoic bedding dipping to the east at about 20 degrees. The 50 square mile Neogene basin created by this graben is bounded on the east by the Eagan Range with nearly 12,000 ft of displacement along west dipping normal faults and on the west by an east dipping with a minimum of 9000 ft of displacement. Mississippian source rocks in the central portion of the graben are well within the oil window and source rock analyses indicate that over 500 million barrels of oil have been expelled from the hydrocarbon kitchen.

In Lake Valley there have been 4 wells drilled for oil and gas exploration and a considerable amount of 2D seismic data. A well drilled by Amoco in1984 and drilled to a total depth of 12,750 ft (BHT 208F) encountered 2,368 ft of Mississippian rocks. Brent Energy drilled a well to a total depth of 9178 ft (BHT 226F) and encountered 1750 ft of Mississippian section. In 2010 Cabot drilled a well to 9515 ft (BHT 128F). Cabot was anticipating a 2100 foot thick section of potential Mississippian source rocks, which seems logical based on the earlier drilling results, but only found 400 ft of source rocks that were not in the oil window. These perplexing results are due to an inordinate thick section of volcanic rocks. The thick section of volcanic rocks encountered in the Cabot well probably have a significantly higher thermal conductivity which accounts for the lower bottom hole temperatures compared to offset wells. The missing Mississippian section in the Cabot well was probably eroded away, possibly by a drainage systems flowing west from the Indian Peak volcanic complex, and then subsequently filed by volcanic rocks with a relatively high thermal conductivity resulting in a thin section of Mississippian Chainman that is not in the oil window.

A curious geothermal anomaly identified in at least one publication on the Beowawe Geothermal system appears to be related to the Miocene Northern Nevada Rift. Magnetotelluric data suggests that the Beowawe system is on a northeast trending resistivity anomaly that originates near the Northern Nevada Rift. Although igneous activity associated with the Miocene Northern Nevada Rift is too old to be directly related to the Beowawe Geothermal system, it appears that secondary northeast trending structures, such as the Malpais Fault, are locally geothermally anomalous. Other northeast trending structures along the Northern Nevada Rift could be geothermal targets for additional geothermal exploration. A blind geothermal system south west of the Beowawe geysers is on trend with this resistivity anomaly and is undoubtedly related to the same northeast trend structure that controls the Beowawe geothermal system.

Anniversary of April 24, 1914 Earthquake in Reno—TODAY

Read this 2006 report for details of the April 24, 1914 earthquake [M6.1 ± 0.3] that hit the Reno area.

The November 21, 1910 Tonopah Junction Earthquake, and the February 18, 1914 and April 24, 1914 Reno Earthquakes in Nevada
by Craig M. dePolo and Terri M. Garside (Open-File Report 2006-02)

“The April 24th earthquake was the largest event in the 1914 Reno earthquake sequence, and it was the largest earthquake in the United States that year. The nighttime earthquake (12:34 a.m. PST) caused damage in Reno, and was felt as far north as Winnemucca, as far east as Elko, as far west as Berkeley, and as far south as Randsburg in California; it might have been felt even further out if it had occurred during the daytime. People were awakened from their sleep as far away as the Great Valley in California, and in Sacramento, people rushed to the streets from buildings in their nightclothes. At least five aftershocks were felt through the night following the mainshock; earthquakes were also reported on April 25 and 26, which were either aftershocks or possibly related to a second earthquake source area to the south, closer to Virginia City.”

The earthquake was most severe at University Hill knocking down two chimneys at Manzanita Hall, leveling two chimneys at Lincoln Hall, and toppling the stack on the Hatch building. Glassware was broken and instruments were upset in the physical and chemical laboratories. At least one residence lost several square meters of plaster in a bedroom, had a chimney shaken to its foundations spilling bricks, and had a broken window. In Virginia City, people who were up dashed into the streets, pictures were jarred from the walls, dishes were thrown from shelves, and plaster was broken from ceilings of some residences.”

Seismic Hazards in the Reno-Carson City Urban Corridor
by Craig dePolo (Nevada Geology, Spring 1992)

“The Reno-Carson City urban corridor has one of the highest seismic hazards in the state of Nevada. Historical earthquakes are often the most convincing evidence of a local seismic hazard, and the Reno-Carson City urban corridor has had several damaging historical earthquakes.”

Living with Earthquakes in Nevada

Speaker: Dr. Paula Noble
Topic: Draughts and Diatoms
Thursday, April 18

Thursday, April 18“Draughts and Diatoms- meet these artful microfossils, explore their tiny glass houses, and discover their long standing affair with beer making”

About this Event

“What is smaller than a sand grain, builds an elaborate glass skeleton, and can be found in virtually every moist environment on earth? Diatoms of course! From volcanic hot springs to Antarctic dry lakes, as oceanic opportunists to desert lake dominators, this group of golden algae leaves behind an intricate fossil record that can help us reconstruct ancient environments. Ranging back to the Jurassic period, diatoms have grown in their importance in the biosphere so that today they produce over 20% of the oxygen we breathe. Diatoms are cool to look at, and darn useful. Not only can ancient species assemblages help reconstruct the past, diatomite deposits can be mined for many industrial purposes including paint, abrasives, and importantly filtration (yes beer!).

Dr. Paula Noble is a professor in the Department of Geological Sciences and Engineering at the University of Nevada Reno where she teaches classes in geology, paleontology, and paleolimnology and advises students in both the Geology and Hydrological Sciences graduate programs. She received her bachelor’s degree in Paleontology from UC Berkeley and a PhD in Geology from UT Austin. Her main research focuses on the combined use of microfossils and sediment chemistry to answer questions about the age of rocks, the evolution and extinction of fossil marine plankton, as well as understanding past climate, anthropogenic impacts, and natural disturbances in mountain lakes. Her field projects are situated in the Sierra Nevada and Great Basin, as well as the Canadian Arctic, central Italy, northern France, eastern Australia, and Turkey. In addition to microfossils, she has recently begun working on late Triassic ichthyosaurs in Shoshone and Pilot Mountains of Nevada with her students and collaborators, Drs. Neil Kelley, Randy Irmis, and Paige dePolo.

This paleo-centric series promises a smörgåsbord of some of the biggest and smallest beasties from the fossil record. Paleontologists Randy, Neil, and Paula (and Luis?) will take you on a tour of their work in the deserts of the world and the finds they have uncovered.”

Speaker: Dr. Luis Chiappe
Topic: Birding in the Age of Dinosaurs
Friday, April 26

Friday, April 26 – “Birding in the Age of Dinosaurs”

About this Event

“Thousands of spectacular fossil birds—many containing plumage, gut contents, and other rarely preserved features—have been recently unearthed from rocks of the Age of Dinosaurs in China. Dr. Chiappe will review this magnificent ancient aviary and explain how these fossils clarify our understanding of early evolution of birds. Luis Chiappe is an Argentine paleontologist born in Buenos Aires who is best known for his discovery of the first sauropod nesting sites in the badlands of Patagonia in 1997. He is currently the Vice President of Research and Collections at the Natural History Museum of Los Angeles County and director of the museum’s Dinosaur Institute.

As Senior Vice President for Research & Collections at the Natural History Museum of Los Angeles County (NHMLA), Dr. Chiappe oversees the academic programs of more than 25 PhD scientists and the vast biological, geological, and cultural collections of NHMLA. A vertebrate paleontologist and the Director of NHMLA’s Dinosaur Institute, Dr. Chiappe has conducted extensive research on the evolution of dinosaurs, from their reproductive behavior to their evolutionary connection with birds. He is considered to be one of the world’s authorities on the subject. Chiappe’s commitment to public communication is reflected in the Museum’s Jane G. Pisano Dinosaur Hall, an award-winning permanent exhibition that he curated about the nature of science and the lives of dinosaurs, as well as in his many popular books and articles. Chiappe¹s research has been published in more than 180 scholarly articles. He is the author of Walking on Eggs, Glorified Dinosaurs, and Birds of Stone. He is also a J. S. Guggenheim Fellow, a Humboldt Awardee, and a professor at the University of Southern California.

He is world-renowned for his research on the origin and early evolution birds, and the curator of the award winning Dinosaur Hall at the Natural History Museum of Los Angeles County.

NBMG Research Featured in Wired Magazine

An article in WIRED magazine recently released describes cutting-edge research by Jim Faulds, Bill Hammond, and Rich Koehler (Nevada Bureau of Mines and Geology) on fault systems in the Walker Lane and how this region could one day become the primary boundary between the Pacific and North American plates.

Move Over, San Andreas: There’s an Ominous New Fault in Town

by Geoff Manaugh (WIRED, Science, 4-18-19, 6:00 AM)

“U.S. Route 395 is a geologic master class disguised as a road. It runs north from the arid outskirts of Los Angeles, carrying travelers up to Reno along the eastern flank of the Sierra Nevada. On the way, they pass the black cinder cones of Coso Volcanic Field and the eroded scars of a mighty 19th-century earthquake near Lone Pine. In winter, drivers might see steam rising from Hot Creek, where water boils up from an active supervolcano deep underground. About an hour from the Nevada border, Mono Lake appears, with its bulbous and surreal mineral formations known as tufa towers. Even for someone with no particular interest in rocks, these are captivating, otherworldly sights. But for James Faulds, Nevada’s state geologist, they are something more—clues to a great tectonic mystery unfolding in the American West. If he’s right, all of this, from the wastes of the Mojave Desert to the night-lit casinos of Reno, will someday be beachfront property.” (Click on link above for complete story.)
