摘 要:Irtysh shear zone is a stretched, but relatively narrow nearfault tectonic zone, which ischaracterized by the following features: a) general sturcture anisotropy (310-320o) with pre-dominance of symmetrical relationships of planar and linear types; b) predominant develop-ment of bended blastomyolnite, blastocataclasite and metamelange fomations; c)regional,but non-uniform foliation of ricks and general manifestation of structures of the shearingflow; d) separation of numerous lenses of mingmatite-like and pegmatoid formations, smallintrusions of leucocratic granites, granite-porphyres and granite-aplites and dike-like bodiesof gabbro-dyabaes and ultrabasic rlcks, rarely.
