Annabk anticline lies in the westernmost side of the Palmyride chain, which
is located in the northern Arabian Plate. It is a 70 km long, NE-SW oriented
asymmetrical anticline, belonging to the southern part of the Palmyrides. The
stratigraphical
column cropping out in the domain of this anticline consists of
Cretaceous and Paleogene strata of marine facies, together with Neogene and
Quaternary continental deposits. The aim of this study is to investigate the
tectonic evolution of this area, by reconstructing its paleostress history, through
analysing the brittle deformations, which were recorded in the outcropping
rocks.
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).
