Abstract

Examples and analyses of recumbent folds of taurian series within the realm of small intrusions of the South coast of Crimea are given, their development in the conditions of vertical pressing/horizontal stretching at the expense of structures of previous stage of folding has been shown. The occurrence of low-temperature cleavage is characterized in paragenesis with recumbent folding of low-temperature pre-greenstone cleavage, possibility of its development within thermal field of the Ayudag gabbro-diabase massif. According to kinematics of faults in the taurian series orientations of the principal tensions have been reconstructed, which confirm formation of cleavage-folded paragenesis under stretching condition. Affixment of extention regime to the epoch of middle Jurassic arc magmatism is proposed.
