Specificities of absorbing anelastic characteristics of zeolite, quartzite, alluvial sandstone sio2, porous polystyrene

Summary The elastic modulus Е, the shear modulus G, Poisson coefficient μ, internal friction Q-1 are dependent from the texture, microcrack formation, minerals anisotropy. The presence of many the acoustic emission secondary maxima indicates the variety of material composition and structure of the rock, a set of allotigenic and authigenic minerals, cement composition, texture, and conveys, to some extent, the nature of the dia- and catagenetic processes. The measuring of internal friction background Q-10 after temperature, mechanical treatments gives information about the changes of the elastic strains σi fields in rock.
