Nevada Petroleum and Geothermal Society
Monthly Dinner Meeting—April 4
Online Registration Ends Monday April 1 at 5 PM
Speaker: Vincent Ramirez
Topic: Western U.S. Obduction Tectonics with Seismic Examples of Deformation in California and Nevada
Abstract: The Coast Ranges of California extend along the entire west side of the Sacramento and San Joaquin Valleys, about 350 miles, and consist of more than 30,000 feet of Cretaceous strata. The Coast Range Thrust separates these rocks from underlying Jurassic basement rocks of ophiolite and blueschist of the Franciscan Formation. Long believed to be a fossil subduction zone of Cretaceous age, deep seismic reflection data (12 seconds) acquired by Shell Oil Company in the 1980’s allows new resolution of these rocks. The Coast Ranges have been uplifted by an east-tapering wedge of Franciscan and ophiolite that was thrust eastward above Sierran granitic rocks, but below the Cretaceous sedimentary rocks.
This process of obduction will be illustrated and described, as interpreted from the Shell seismic data, a subsurface study of 5,000 wells, and outcrop maps from several regions of the Coast Ranges.
The Coast Range Thrust is younger than previously interpreted, and most movement is post-Eocene. Overturned Quaternary rocks demonstrate the fault complex is still active.
The magnitude and style of deformation along the obducted wedge of the Coast Ranges has implications throughout the western US, where seismic examples from Nevada and Wyoming are seen to be similar in style and timing.
Shell Western E & P Inc. is gratefully acknowledged for the release of these proprietary seismic data.
Bio: Vincent Ramirez has a M.A. degree in Geology from UC Santa Barbara, is the CEO of a Nevada lithium exploration company, and CEO of a domestic U.S. oil company. He previously worked for Shell Oil in Alaska, the continental U.S., and Yemen as an exploration geologist. He has drilled 61 oil and gas wildcats worldwide, including 44 discoveries. While at Shell Oil, Vincent also was the Operations Manager for the San Joaquin Basin, and he was the appointed Structural Geology instructor at the Shell Research Lab.
Vincent discovered and developed several oil fields in central Siberia during 10 years with the Lundin Group. During this time, he transformed an oil company from bankruptcy to $850 Million in value, drilled the highest-producing well in Russia (11,500 BOPD), and drilled the first multi-lateral wells in Russia, while overseeing 350 employees as CEO.
He has published extensively on structural geology subjects, including the San Andreas Fault, Ridge Basin, the California Coast Ranges, and Obduction Tectonics. Vincent’s geologic presentations often are forward-thinking and controversial.
