Реконструкция полей напряжений Кокджотского блока Малого Каратау (Южный Казахстан)

Reconstruction of the paleostress field of the Kokdjot Block, Malyi Karatau ridge (South Kazakhstan) was done as a result of the detailed structural study. Kink-bands and fold-axes were used for indicate stress field reconstruction. Study areas of the Kokdjot Block are located from the northwest to the southeast of the Kokdjot plateau and are characterized as both clastic sedimentary rocks of greenschist and phyllite facies of metamorphism and clastic and carbonates sedimentary rocks. Two stress fields have been identified as corresponding to Caledonian (Late Ordovician) and Hercynian deformations. The earlier tectonic event is characterized by horizontal compression of the northeastern trend and later tectonic event is characterized by the shear stress field at the west-north-west trend of the compression axis.
