Crustal thickness beneath Rio de Janeiro, Brazil, from spectra of SH waves at station RDJ [PDF]

open access: yesGeofísica Internacional, 2006
Amplitude and phase spectra of long period analog S wave records were used to estimate crustal thickness under Rio de Janeiro seismic station. Earthquakes with shallow focal depths (10-33 km) and epicentral distances varying from 83 to 88 degrees ...

Geodynamics and Rate of Volcanism on Massive Earth-like Planets [PDF]

open access: yes, 2009
We provide estimates of volcanism versus time for planets with Earth-like composition and masses from 0.25 to 25 times Earth, as a step toward predicting atmospheric mass on extrasolar rocky planets. Volcanism requires melting of the silicate mantle.

Satellite magnetic anomalies of the Antarctic crust

open access: yesAnnals of Geophysics, 2000
Spatially and temporally static crustal magnetic anomalies are contaminated by static core field effects above spherical harmonic degree 12 and dynamic, large-amplitude external fields.

Structural boundary and deep contact relationship between the Yangtze and Cathaysia Blocks from crustal thickness gradients

open access: yesFrontiers in Earth Science, 2023
The deep boundary and contact relationship between the Yangtze and Cathaysia Blocks (the major tectonic units of the Southern China Block), as well as the tectonic attributes of the Jiangnan Orogenic Belt, have remained unknown or controversial.

Influence of crustal layering and thickness on co-seismic effects of Wenchuan earthquake

open access: yesGeodesy and Geodynamics, 2011
Using the PSGRN/PSCMP software and the fault model offered by USGS and on the basis of finite rectangular dislocation theory and the local layered wave velocity structures of the crust-upper-mantle, the influences of crustal layering and thickness on co ...

Influence of pre-Andean history over Andean foreland deformation: structural styles in the Malargüe fold-and-thrust belt at 35ºS, Andes of Argentina [PDF]

open access: yes, 2014
We present the first complete balanced cross-section of the Argentinean Andes at 35ºS. Based on an extensive field survey and limited sub-surface information, we constructed a structural model in which both the tectonic inversion of Mesozoic normal ...

Moho Geometry of the Okinawa Trough Based on Gravity Inversion and Its Implications on the Crustal Nature and Tectonic Evolution

open access: yesFrontiers in Earth Science, 2021
The Okinawa Trough (OT) is an incipient back-arc basin, but its crustal nature is still controversial. Gravity inversion along with sediment and lithospheric mantle density modeling are used to map the regional Moho depth and crustal thickness variations

Lateral variations in the crustal structure of the Indo-Eurasian collision zone [PDF]

open access: yes, 2018
We thank Michael Ritzwoller and two anonymous reviewers for constructive comments that have helped improve the manuscript. The majority of the seismic data used in this study were downloaded from IRIS DMC.

Crustal structure in the Anyuan Coal Mine and its adjacent areas of Jiangxi Province by P-wave receiver functions

open access: yesEarthquake Research Advances
We collected high-quality teleseismic events recorded by 12 broadband seismographs deployed in the Anyuan Coal Mine and its adjacent areas in Pingxiang City, Jiangxi Province for nearly two years.
