Resumo

The complex of felsic rocks, intruded by plagiogranitic bodies are first revealed in the west of the Tekturmas ophiolite zone of Central Kazakhstan. The U–Pb (SIMS) geochronological study of one of the plagiogranitic bodies was carried out and the Early Cambrian age (537 ± 5 Ma) was first obtained. The peculiarities of effusives and plagiogranites composition indicate their formation in the supra-subduction setting within primitive volcanic island arc. Formation of this arc was not related to the evolution of the oceanic structures, which complexes participate in the structure of the Tekturmas zone.
