2.6. During 1996-1998 we have carried out a complex field and laboratory study of particular class of the geological objects, which we named strike-slip magmatic duplexes (SSMD), in limits of the Eastern Urals, Central Kazakhstan and Kola-Karelia region. The important results of these works are as follows.

(1) We created a general database on strike-slip magmatic duplexes including bibliographic and geochemical information, designed extended package of applied softwear for processing and visualizations of geochemical, petrological, mineralogic and structural data.

(2) We recovered within the Eastern Urals a series of geological objects identidied as SSMD of different age and of different deepness, and studied them in detail due to field investigations.

(3) A series of geological maps in different scales is produced for areas of SSMD localization within the South Urals.

(4) There were composed the regoinal structural maps for the Variscan area of Kazakhstan and for the Eastern Urals.

(5) Comprehensive classification of SSMD is elaborated.

(6) We constrained detailed kinematic models for every type of SSMD.

(7) For SSMD with the massifs of high-K alkalinity it was suggested a new petrological model.

(8) It has been developed the general geodynamical model of SW part of the Uralo-Mongolsky foldbelt, and as well series of detailed SSMD models for some of its zones.

(9) It has been studied dynamical evolution of SSMD under crust shear conditions.
