Fracturing of the Crust — Geological and Geophysical View

In suggested analysis of a status and develop-
ment of the Earth crust rupture experiments under
high �-� conditions of rock samples are used in
their comparison to geophysical studies, namely to
available information about deep-seated fractures
and faults in the crust and the upper mantle. Using
scaling approach (transmission of data about a fi-
nite status of rock cores on scales of the earth crust)
in comparison to results of deep seismic sounding,
magnetotelluric, petrophysic and geochemistry data.
Initial representations are that. If rock massifs
on strength properties are close to the properties to
granite, brittle failure (including cataclastic) is pos-
sible up to Moho boundary and, therefore, a crust
as a whole hydraulically permeable for water and
gases. The quantitative deviations in strength (am-
phibolites, peridotites, serpentinites, basalts, etc.
from granite) result in to wide gamma of alternatives
of a constitution of the crust responding an obser-
vable geologic variety. (Including to differences con-
tinental and oceanic)
Including water as geologic factor ensures differ-
ence of crustal and mantle rocks, changes dyna-
mics of destruction, and installing units of self-or-
ganisation during lithosphere evolution. Presence
of water at destruction in the lower crust result in
faults in amphibolites, to melting of granite, cance-
ling Kennedy — Ito limitation on phase boundaries
“basalt — eclogite” and provides appropriate kine-
tics of transformation events demanded in common
theories modifications of material on Moho and its
transmission and accumulation in lithosphere co-
lumn. Known peculiarities in metamorphism and
metasomatism also are connected with presence
and absence of water.
In the earth crust there are in essence relevant
differences in brittle destruction. They depend on a
geotherm with depth and a concurrence of vertical
and horizontal stresses that explains existence of
waveguides by a flattening of deep-seated faults in
middle crust. Modifications of seismic rates now it
is stipulated not only petrology of the rocks, but
also by level of their fracturing. Voidage of system
of cracks is responsive to field distortions of the
stresses manifested both at earthquakes, and at
quasi-stationary development of tectonic events.
