Three-layered model of Earth's crust of continental type and Young modulus and
porosity distribution
It’s ascertained that Young modulus and porosity distribution gotten with using
experimental researching gas permeability don’t contradict three-layered model of Earth's
crust of continental type, which has been creation with using seismic investigations.
Key words: seismic investigations, Earth's crust structure models, gas permeability,
porosity, Young modulus.

Poisson's ratio, porosity and opening micro-cracks in deep parts of Earth's crust
The dependences between porosity and Poisson's ratio were gotten. These dependences
make it possible conclusions about steadiness of micro-cracks in deep parts of continent type
Earth's crust. The micro-cracks aren’t steadiness for different means of Poisson's ratio if porosity
more than 2.25 %.
Key words: effective pressure, fluids, porosity, Poisson's ratio, Young modulus,
micro-cracks.
