High resolution electromagnetic methods and low frequency dispersion of rock conductivity
electromagnetic sounding induced polarization frequency dispersion of conductivity resolution of sounding mathematical modelling
2015/10/8
The influence of frequency dispersion of conductivity (induced polarization) of rocks on the results of electromagnetic (EM) sounding was studied on the basis of calculation of electric field of verti...
An integrated study of physical precursors of failure in relation to earthquake prediction, using large scale rock blocks
precursors simulation failure complex parameter prediction earthquake
2015/9/30
This paper is multi-analysis approach to rock failure using metric size rock samples. The use of large-scale models permits simulation of the seismic process (including internal rupture on several sca...
The electrical signature of rock samples exposed to hydrostatic and triaxial pressures
Electrical impedance spectroscopy fracturing carbonate amphibolite pressure
2015/9/28
The electrical signature of sedimentary (carbonate) and crystalline rock samples was studied in hydrostatic and triaxial pressure experiments up to 300 MPa. The aim was to establish a relation between...
The spectrum of thermally stimulated currents in rock samples from KTB drilling:preliminary results
thermally stimulated depolarization currents (TSDC) KTB drilling rocks relation parameters
2015/9/28
The technique of thermally stimulated depolarization currents (TSDC) was applied to fine grained amphibolite rock samples extracted from KTB drilling. Each sample was cooled down to liquid nitrogen te...
Integrated geophysical and geological investigations applied to sedimentary rock mass characterization
sedimentary rock mass quality stratigraphy seismic refraction tomography ERT

3.8 Billion-Year-Old Rock Sequence Found in Greenland Revises Tectonic Timeline（图）
plate tectonics crust
2007/3/26
23 March 2007，A 3.8 billion-year-old sequence of rocks from Greenland is helping scientists pinpoint when the Earth's plate tectonics system kicked into gear, according to new research in the 23 March...
Amphitheater-headed valleys on Earth and Mars are often assumed to result from erosion by emerging spring water (i.e., seepage erosion or groundwater sapping) rather than by surface runoff. The origin...
Magnetostratigraphy and rock magnetism of the Neogene Kuitun He section (northwest China): implications for Late Cenozoic uplift of the Tianshan mountains
Tianshan uplift magnetostratigraphy AMS
2014/4/15
In order to better constrain the tectonic evolution of central Asia under the influence of the India–Asia collision, we carried out a magnetostratigraphic study at the Kuitun He section, on the northe...
