Temperature and pore pressure effects on the shear strength of granite in the brittle-plastic transition regime [PDF]
Currently published lithospheric strength profiles lack constraints from experimental data for shear failure of typical crustal materials in the brittle-plastic transition regime in wet environments.

Natural stone assessment with ground penetrating radar [PDF]
The usability of ground penetrating radar in quality assessment of natural stone deposits was tested in porphyritic granite and soapstone. The main interest was to evaluate how the soundness, fracturing, and physical defects can be studied with the ...

Problems of Precambrian paleomagnetism on the territory of Ukraine
Some problems of paleomagnetic research of the Precambrian rocks of Ukraine are considered. The results of paleomagnetic researches of the Proterozoic rocks of the Ukrainian Shield, Ediacaran traps of Volyn and sedimentary rocks of Podolia were analyzed.
