KAZAKHSTAN FOLD REGION OPHIOLITE STRUCTURE’S FEATURES AS THE PROOF OF REGIONAL PRESENTATION OF PLATE TECTONICS IN PALEOZOIC

It is believed that the structure of the ophiolite are witnessing the existence of oceanic crust in the Earth’s history, according to the transformed plate tectonics, manifested in a global (all planetary) scale. Therefore, all researchers geology Kazakhstan ophiolite zones of the folded area is identified as “intraplate structure” separate at the close of the largest Paleo-Asian Ocean. However, several features of the Paleozoic ophiolite zones of Kazakhstan makes seeing them as structures formed as a result of the opening and closing of micro -ocean basins. This conclusion leads: Paleozoic microscale structures of Kazakhstan and their different orientation in space; their alternation with Precambrian continental blocks; melange structure; formational usefulness (in the presence of fragments within the geological associations such as the disclosure of the oceanic phase of the structure and its closure). The author shows in this article as examples of well-studied two representative structures, there are Tekturmasskaya and Bozshakolskaya ophiolite zones. These findings call for examining the structure of the Paleozoic ophiolite as fold-thrust structures formed in the “interplate conditions”. The author refers to them as “micro-ophiolite belt”, the inception, development and establishment of which took place in full compliance with the concept of plate tectonics, manifested on a regional scale Features of the studied zones and deformation behavior of their constituent geological complexes allow to identify six stages of the structure corresponding to the “Wilson Cycle”: rift, ocean, island arc, before the collisional, collisional (orogenic), platform.
