Crumbling marble
Hello Andrei
I was thinking on marble and anisotropic behavoir.
Marble itself is not a sedimentary rock. It is a
metamorphic rock resulted from the transformation of
limestones at high levels of pressure and/or
temperature.
In this way, sometimes the transformation is not
complete and the resultant rock may have rests of the
original limestone. This may be the sugar-like spot of
your marble: rests of the original limestone that did
not metamorphize at all. The one-way behavoir may be
related to deposition and metamorphic conditions of the
rock.
Allthough, let me ask another geologysts to have a
better idea.
Hope I have helped you
Daniel
