open access: yes, 2022
Includes charts. Unscanned drawing, contact the Library for more information.The United States Bureau of Mines facility at Anvil Points, near Rifle, Colorado, was reactivated starting in May 1964 and was operated during 1965, 1966, and 1967.

Seismic imaging of the critical zone of dolerite dykes at Cap Fréhel in Brittany (France)

open access: yesNear Surface Geophysics, Volume 24, Issue 3, Page 262-288, June 2026.
Abstract In June 2023, we measured ten near‐surface seismic profiles to image the critical zone of dolerite (diabase) dykes that cut the sandstone at Cap Fréhel in Brittany (France). Seismic ray tracing and inversion are used to determine the thickness of the regolith layer from first‐arrival P‐wave traveltimes.

Mechanistic investigation of gas injection treatment in a continental shale gas condensate reservoir

open access: yes
Low thermal evolution degree of gas and connected fracture network are key features in the continental shale gas reservoirs. When the pressure decreases lower than the dew point pressure, gas condensate diminishes the mobility of subsurface fluid forms ...

Mineralogical characteristics of continental shale: a case study in Yan-Chang Formation, Ordos Basin

open access: yes, 2018
The Chang 7 Member of the Yan-Chang Formation (Yan-Chang #7 Member), which is located in the central south of the Ordos Basin (China), is assessed for its potential as a shale gas resource.

The United States Magnetotelluric Array and the National Impedance Map

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract The United States Magnetotelluric Array (USMTArray) data set, collected in the years 2006–2024, consists of more than 1,700 long‐period magnetotelluric stations covering the entirety of the contiguous United States on a quasi‐regular 70 km grid.

New Insights Into Hikurangi Subduction Inputs and Megathrust Host Rocks Spanning Along‐Margin Changes in Fault Slip Behavior

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The seismic behavior of subduction megathrusts varies spatially and is influenced by the properties of subducting plates, including their sedimentary cover. Characterizing these subduction inputs is essential for understanding the mechanisms behind fault slip variability.

Impact and Crystallization Modeling of the Sudbury Basin and Its Implications for a Hadean Crust

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract The 1.85 Ga Sudbury Structure hosts Earth's largest and best‐preserved impact‐induced melt sheet, the Sudbury Igneous Complex (SIC), which crystallized into distinct noritic, gabbroic, and granophyric layers. We conduct impact simulations with iSALE‐2D and crystallization modeling using alphaMELTS 2 to track the formation and evolution of the ...
