Thermochronologic Constraints on the Extensional History of the Ibex Hills, Southeastern Black Mountains, Death Valley, California

open access: yesGeological Journal, EarlyView.
A. Modeled T‐t paths for samples in the northern Ibex Hills, showing steady cooling throughout much of the Cenozoic, until rapid Miocene cooling. B. Weighted mean paths for each sample in this study. Note that all show a rapid cooling event at or just after 10 Ma, which is interpreted to represent exhumation as a result of regional extenstion ...

Interpretation of the aeromagnetic anomalies of mainland Scotland using pseudogravimetric transformation and other methods [PDF]

open access: yes, 1990
A procedure to upward continue magnetic anomalies observed on an irregular surface onto a horizontal plane has been developed and applied to the aeromagnetic map of Great Britain.

Notable Impact of Paleotectonic Stress on Gold Mineralisation in the West Qinling Orogen

open access: yesGeological Journal, EarlyView.
By applying fuzzy clustering and multiple inverse methods, we systematically processed the data of vein and fault slip in this ore deposit to reveal the transition of orogenic geological environment and paleotectonic stress field. Our research results show two different stress states: the northwest–southeast extensional stress field and the northeast ...

Numerical analysis of deformation in the upper part of subduction zones [PDF]

open access: yes, 1981
The stresses and deformation in an accretionary prism, and the crystalline basement behind and beneath it, have been modelled using finite element analysis, assuming a visco-elastic Maxwell rheology for the rocks involved.

Multiphase Tectonic Process With Slab Dynamics in the Northern East China Sea Shelf Basin

open access: yesGeological Journal, EarlyView.
Megasequence 1 characterised by Palaeocene extension and differential subsidence driven by the rollback of the subducting Izanagi Plate. Megasequence 2 records a kinematic reorganisation of the East Asian margin, transition from a rifting to a compressional regime.

Creation of a Landslide Susceptibility Map Using Short‐Term Data From the July 2018 Heavy Rainfall in Southern Hiroshima Prefecture

open access: yesGeological Journal, EarlyView.
This work advances landslide susceptibility mapping by incorporating short‐term trigger data with landscape susceptibility mapping. We also examine the importance of downsampling, watershed delineation and geospatial correlations in evaluating outcomes.

Present-time crustal deformation in China and its surrounding regions by GPS

open access: yes, 2002
Applying recent 10-year GPS measurement data from several nationside GPS networks, serveral regional GPS monitoring networks and the Asia-Pacific Regional Geodetic Project (APRGP), we give out a combined and consistent velocity field solution in ITRF97 ...

Measurements of crustal deformation in India

open access: yesMAUSAM, 1979
Development of instruments for the purpose of measurement of crustal deformation  at suitably selected location in Indian was started in 1967 at the Training in Earthquake Engineering , university of Roorkee. Now Several permanent observatory vaults have been constructed and limited measurement done employing the instrument developed.
