Discoidal structure of the lithosphere [PDF]

open access: greenProceedings of the National Academy of Sciences, 1920
Advanced Summary The following discussion seeks to determine inductively the structural character of the lithosphere at depths beyond the reach of observation. The mechanical state of the outer shell of the lithosphere is discussed on the basis of Adams’ experiments with rocks under confining pressures, which demonstrate that pressure increases the ...

The Changing Face of the Lithosphere‐Asthenosphere Boundary: Imaging Continental Scale Patterns in Upper Mantle Structure Across the Contiguous U.S. With Sp Converted Waves

open access: yesGeochemistry, Geophysics, Geosystems, 2018
Juxtaposed terranes of highly varied tectonic history make up the contiguous U.S.: the tectonically active western U.S., the largely quiescent Archean and Proterozoic cratons of the central U.S., and the Phanerozoic orogen and rifted margin of the ...

The subantarctic lithospheric mantle [PDF]

open access: yesGeological Society, London, Memoirs, 2021
Abstract We present a summary of peridotite in the Subantarctic (46–60° S) surrounding the Antarctic Plate. Peridotite xenoliths occur on the Kerguelen Islands and Auckland Islands. The Kerguelen Islands are underlain by a plume, whereas the Auckland Islands are part of continental Zealandia, which is a Gondwana-rifted fragment. Small amounts

Time-dependent frictional properties of granular materials used in analogue modelling: implications for mimicking fault healing during reactivation and inversion [PDF]

open access: yesSolid Earth, 2023
Analogue models are often used to model long-term geological processes such as mountain building or basin inversion. Most of these models use granular materials such as sand or glass beads to simulate the brittle behaviour of the crust.

Application of active-source surface waves in urban underground space detection: A case study of Rongcheng County, Hebei, China

open access: yesEarth and Planetary Physics, 2022
Active-source surface wave exploration is advantageous because it has high imaging accuracy, is not affected by high-speed layers, and has a low cost; thus, it has unique advantages for investigating shallow surface structures.

Surface wave imaging using deep reflection seismic data: a study on the Cuonadong dome

open access: yesEarth, Planets and Space, 2022
As interference waves in deep reflection data processing, surface waves are often suppressed as noise, but surface waves carry considerable underground media information, including structural information and the physical properties of rocks.

Possible Correlations between the ULF Geomagnetic Signature and Mw6.4 Coastal Earthquake, Albania, on 26 November 2019

open access: yesEntropy, 2021
An earthquake of Mw6.4 hit the coastal zone of Albania on 26 November 2019, at 02:54:11 UTC. It was intensively felt at about 34 km away, in Tirana City, where damages and lives lost occurred.

Corona structures driven by plume–lithosphere interactions and evidence for ongoing plume activity on Venus

open access: yesNature Geoscience, 2020
In the absence of global plate tectonics, mantle convection and plume–lithosphere interaction are the main drivers of surface deformation on Venus. Among documented tectonic structures, circular volcano-tectonic features known as coronae may be the ...

Anomalous Geomagnetic Signal Emphasized before the Mw8.2 Coastal Alaska Earthquake, Occurred on 29 July 2021

open access: yesEntropy, 2022
A very strong earthquake of magnitude Mw8.2 struck the coastal zone of Alaska (USA), on 29 July 2021. This earthquake was felt around the Gulf of Alaska, on a wide offshore area belonging to USA and Canada.

Intraplate lithosphere deformation and the strength of the lithosphere [PDF]

open access: yesGeophysical Journal International, 1984
Summary. The intraplate deformation of continental lithosphere in response to applied stress has been investigated using a mathematical model which incorporates the elastic, ductile and brittle response of lithosphere material. Ductile deformation is assumed to be controlled in the crust by dislocation creep in quartz, and in the mantle by dislocation ...
