oint Inversion of the 3D P Wave Velocity Structure of the Crust and Upper Mantle under the Southeastern Margin of the Tibetan Plateau Using Regional Earthquake and Teleseismic Data
3D P-wave velocity structure China seismic array detection Panxi region Chuan-Dian Block Daliangshan Block southeastern margin of Qinghai–Tibet Plateau
2018/4/10
The special seismic tectonic environment and frequent seismicity in the southeastern margin of the Qinghai–Tibet Plateau show that this area is an ideal location to study the present tectonic movement...
Major and trace element compositions and resource potential of ferromanganese crust at Takuyo Daigo Seamount, northwestern Pacific Ocean
Fe-Mn crust Takuyo Daigo Seamount northwestern Pacific Ocean resource potential evaluation
2017/4/10
We report major element and trace element compositions of ferromanganese crusts (Fe-Mn crusts) on Takuyo Daigo
Seamount, northwestern Pacific Ocean. Highly enriched elements in these crusts, such as ...
The separation of the geomagnetic field originated in the core, in the asthenosphere, and in the crust
dynamo spatial spectrum white spectrum Lowes’ law Nevanlinna’ s law Hamilton’ s principle geomagnetic anomalies inner core outer core asthenosphere
2015/10/8
The separation of the field produced by different internal sources can be accomplished by means of the so-called spatial spectrum of the geomagnetic field of internal origin. It is shown how such a ra...
In search of evidence of deep fluid discharges and pore pressure evolution in the crust to explain the seismicity style of the Umbria-Marche 1997-1998 seismic sequence (Central Italy)
fluid geochemistry/seismicity porepressure field Umbria-Marche 1997-1998 seismic sequence
2015/9/30
Starting soon after the first main-shocks of the long seismic sequence which has occurred along the Umbria-Marche boundary since September 1997, fluid geochemistry surveying was accomplished (around 2...
Satellite magnetic anomalies of the Antarctic crust
Antarctic crust magnetic anomalies ADMAP satellite surveys airborne surveys
2015/9/28
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. To extract cru...
Resistivity and heterogeneity of Earth crust in an active tectonic region,Southern Tuscany (Italy)
crustal exploration magnetotellurics geothermal areas
2015/9/14
Southern Tuscany, belonging to the inner zone of the Northern Apennines, Italy, is an ideal laboratory for observing the physical features of the lithosphere and their evolution in tectonically active...
Low velocity and low electricalresistivity layers in the middle crust
seismic and electromagnetic studies Earth's crust Baltic and Ukranian shields
2015/9/14
Some Deep Seismic Sounding (DSS) revealed low velocity layers in the upper and middle crust of old platforms.The layers are often characterised by a lower electrical resistivity. It is not clear, howe...
Anomaly crust fields from MAGSAT satellite measurements:their processing and interpretation
MAGSAT satellite data magnetic andgravity anomalies wavelet and maximum entropyanalysis earthquake hypocenters
2015/9/14
The space distribution of the magnetic anomaly field for the Pacific Ocean is obtained from data of the satellite MAGSAT. A number of long-wavelength magnetic anomalies of the region are identified. A...
Cooling of a channeled lava flow with non-Newtonian rheology: crust formation and surface radiance
Rheology Magmas Thermodynamics Lava flow Effusion rate
2015/8/27
We present here the results from dynamical and thermal models that describe a channeled lava flow as it cools by radiation. In particular, the effects of power-law rheology and of the presence of bend...
