Paleostress Evolution in the Mrah Anticline «Northern Palmyride fold belt. (Syria)»

The study was made in the region of the NNE-SSW trending Mrah anticline. This anticline is one of the main anticlines belonging to the Northern part of the Palmyride fold belt, lying amid Syria, in the northern Arabian plate. The lithostratigraphic column of the study area consists of the marine sediments of upper Cretaceous and lower Paleogene age. The field study involved the description and measurement of the brittle deformations in ٢٥ sites, which are distributed stratigraphically and geographically in the different parts of the Mrah anticline. Data processing and field observations led to a reconstruction of the principal stresses, which affected the region, and their evolution relative to the main folding phase (Neogene-Quaternary).

Study of the temperature effect, pressure and geological times on the sedimentry rock in the Palmyrian folding zone the isolation and posipole hydrocarbonic formations

Considering the importance of the Palmyrian folding zone as one of the promising zones, and the scientific and practical importance of the isolation of the matrix formation in any sedimentary basin or in any part of it, and that the sedimentary rocks, which have sufficient quantity and quality of organic materials cannot become matrixes until they undergo convnient conditions of temperature, pressure and geological time, the aim of this work is to study the effect of these factors on the sedimentary rocks of the investigated ones and to isolate the formations, which may be matrixes. According to the results of this study,the formations which may play the main role as matrix are these which have Middle Triassic age or Paleozoicin the northern Palmyrian subzone, and older than Permian age in the southern Palmyrian subzone .
