Rocks at asteroid impact site record first day of dinosaur extinction（图）
Rocks asteroid impact site record first day dinosaur extinction
2019/10/18
When the asteroid that wiped out the dinosaurs slammed into the planet, the impact set wildfires, triggered tsunamis and blasted so much sulfur into the atmosphere that it blocked the sun, which cause...
Acoustic emission responseof rocks to electric power actionas seismic-electric effect manifestation
acoustic emission activity energy impact rock
2015/9/14
Two parts of the research are distinguished in this paper. The first part is devoted to the structure of signals of Acoustic Emission (AE) and electromagnetic emission (EME) which accompany the inelas...
Self-oscillations in rocks,results of laboratory experiments
self-oscillations mechanoelectricself-oscillator transformations rocks
2015/9/14
The method of generation of self-oscillations in rocks is developed here. Self-oscillations arise as a result of direct and inverse mechanoelectric transformations without an external generator. Labor...
Determination of volatiles in volcanic rocks and minerals with a Directly Coupled Evolved Gas Analyzing System (DEGAS) -Part I: Interpretation of degassing profiles (DEGAS-profiles) of minerals and rocks on the basis of melting experiments

2015/9/10
Volatile components in magma strongly influence many physical properties of melts and minerals. The temperature
resolved degassing analysis of volcanic crystalline and vitreous rocks gives detailed i...
Correlation of pressure stimulated currents in rocks with the damage parameter
Pressure Stimulated Current (PSC) damage parameter fracture
2015/9/2
Pressure Stimulated Current (PSC) experiments were conducted on marble samples to correlate PSC with the damage parameter, D. The phenomena and procedures taking place in the vicinity of the fracture ...

Strain localisation in mechanically layered rocks beneath detachment zones: insights from numerical modelling
Fully dynamic numerical simulation of the seepage plate separation zone mode localization testing
2015/1/5
We have designed a series of fully dynamic numerical simulations aimed at assessing how the orientation of mechanical layering in rocks controls the orientation of shear bands and the depth of penetra...
A simple method for solving the Bussian equation for electrical conduction in rocks
Bussian equation electrical conduction in rocks
2014/12/31
One of the most general and effective models for calculating the complex electrical conductivity and relative dielectric permittivity of rocks saturated with pore fluids is that of Bussian. Unlike mos...

A new study by the University of Pennsylvania's Douglas Jerolmack, working with mathematicians at Budapest University of Technology and Economics, have found that rocks follow a distinct pattern as th...
Determination of boron and fluoride sources in groundwater: Batch dissolution of carbonate rocks in water
boron fluoride carbonate rock water-rock interaction batch dissolution
2017/4/11
High natural fluoride (up to 6.1 mg/l) and boron (up to 2.1 mg/l) concentrations in groundwater are recorded in western
Estonia, where a carbonaceous Silurian–Ordovician aquifer system is the main so...
Reactive-infiltration instabilities in rocks. Fracture dissolution
Reactive-infiltration instabilities rocks Fracture dissolution Fluid Dynamics
2012/4/19
A reactive fluid dissolving the surface of a uniform fracture will trigger an instability in the dissolution front, leading to spontaneous formation of pronounced well-spaced channels in the surroundi...

rocks in the Taiwan orogen on crustal stress levels rheology
2014/4/15
Taiwan’s Hsüehshan range experienced penetrative coaxial deformation within and near the brittle-plastic transition between6.5 and 3 Ma. This recent and short-lasting deformation in an active, well-s...
Water-induced granular decomposition and its effects on geotechnical properties of crushed soft rocks
Water-induced granular geotechnical properties of crushed soft rocks
2010/10/20
The widespread availability of soft rocks and their increasing use as cheap rockfill material is adding more to geotechnical hazards because time-dependent granular decomposition causes significant da...
Microstructure induced nonlinearity of unconsolidated rocks as related to seismic diagnostic problems
Microstructure induced nonlinearity unconsolidated rocks seismic diagnostic problems
2009/11/13
Manifestations of the so-called structure induced nonlinearity are considered for the case of a granular medium, the latter being a generally accepted model of nonconsolidated rocks in seismics. The c...
