The influence of compressive stresses on folding in the Middle Kura depression and the Turkmen shelf


 On the basis of morphology folds, their three-dimensional position, types faults and development mud volcanism, features spread compres- sive stresses influence on oil gas bearing Kura Gabirri interfluve, Yevlakh-Agjabedi depression Godin massif were studied. For this purpose, maps isomorphs morphological schemes, positions local folds plan each these structural elements compiled. It has been established that within depressions, process folding took place due to mechanisms longitudinal latitudinal bending, which led formation mostly linear brachiform them. The high intensity compressive with- in interfluve contributed volcanism here, increase at end Miocene emergence disharmony here plans between Cretaceous-Eocene Oligocene-Quater- nary complexes sediments. Barda Shirvanli structures located along section was investigated it determined they had an uneven development. fold, is southwestern zone region, a height 50-70 m according top Late Cretaceous. According Paleocene, reached 150 m, carbonate layer, forms lower part Eocene, fold developed 300 m. began form more intensively Maikop age reason for mobility clay sediments activation stress. structure Cretaceous proves its hereditary origin. northeast Eocene express itself as terrace. does not by bottom Paleocene washed surface complexes, but sedimentary complex, with greater than thickness core confirms clays play key role fold. At same time, significant decrease Sarmatian Chokrak crest mentioned indicative syn-depositional time interval. As clear from developmental both , are diapiric origin, relatively weak stresses, low layer lying sediments, did have necessary energy potential fully realize diaprism. bending mechanism weak. effusive significantly limits activity compressional stress area. Compressive effect formed Oligocene-Miocene northwestern slope depression, weakly expressed Neogene regional erosion second half age. should be noted period Cretaceous, faced Maikop. Within massif, disordered testify absence process.
