Joints study in Skhaba region shows the existence two joint directions, principal dominant
NW-SE Joints from extension origin upper Cretaceous age, unrelated and older than faults
in studied area statistically, the presence of Calcareous filling in
the joints that is supported
the extension origin in the first phase. Secondary NE-SW joints from Miocen-Pliocen in
age, and from extension origin ,related to the formation of faults, most of them contain thin
iron crust in secondary phase.
In this paper, we will shed light on the applied studies results in
special of deep tectonic situation of the Kurachine dolomite
formation through the seismic sections explained by us, and
establish time and depth maps for this formation, and prop
osing a
well that is supposed to be hydrocarbon potential in the light of
modern data.
Abo Rabah is one of the most important structures in the Al- Daw
basin, because of the great tectonic complexity that has been
exposed during the geological history, and being one of the most
important gas producing areas in Syria. That explains t
he
importance of its study. Our applied studies indicates that there is
significant variation in salt thickness depending on sedimentation
and tectonic factors, which directly affects the kurachine dolomite
gas reservoir, Here lies the importance of this paper.
The study of fracture in Kadmous and Safita showed several
fracturing directions, originally related to the tectonic structure of
the studied zone, especially faults. A group of dominant principal
fractures, with a direction of NW-SE, a group of less importance
with direction of NE-SW, and a secondary group of N-S direction,
have been determined.
The aim of this research is to identified the tectonic evolution of
Naher Al-Kabir Al-Shimaly Basin from tectonic subsidence curve
witch calculated from Lattakia1 well data. Tectonic subsidence
was identified in lower-middle Jurassic en relation o
f opening of
East Mediterranean basin. A subsidence is occurred in
Cenomaniane, after a stage of uplift in late Jurassic-lower
Cretaceous en relation to fold and erosion known at regional
scale.
Study of faults at Lattakia region shows normal, reversed and
strike-slip faults. Main fault directions and their geologic age
estimation were determined. The normal faults have NE-SW
main direction from Middle Miocene and E-W secondary
direction from Paleogene.
The study of Quaternary terraces in the south of the coastal chain, safita and Marmaritadistrict, constitute a great importance in understanding the geological and structural conditions, that prevailed in the region in that period. The rivers Abrash
andAL-Arousplayed a major role in the formation of these quaternary terraces from the lower Quaternarytill Holocene. These terraces were distributed on a narrow space and points spread over the basins of the rivers in the south of the coastal chain. The high of these terraces, between tens to hundreds meters, are a strong indicator of the advancement of theuplift movements affecting the region in recent times, compared with the uplift of that terraces of other important riverssuch the Euphrates and Nahr El-Kabir-Ash-Shemaliriver,according to thestratigraphy and lithology studies, using GPStechniques to determinethe sites high et compare these values with global data, and then appreacitethe tectonic effect on the region. A numerical model tectonicactivity– terraces uplift is proposed.
The statistical Study of Jointsarround 16 Tishreen lake dame region in ALKabir
ALShimali river basin showed the presence of several main groups of Joints with
directions NE-SW _ NNE-SSW, NW-SE, E-W.
- Group NE-SW: showed correspond to with the fau
lt structures of same directions
which are normal and reversal faults and distributing geographically 1n Lattakia Kallas
fault zone. Also it showes correspond to with the axis of folds of same direction, thus
explained as longitudinal joints within these folds
- Group NW-SE: showed correspond to with faults structures of same direction.
which are left and right lateral strike slip faults, Spread over the entire study area. and it
may(diagonal)shear group within the folds of NE-SW axes.
- Group E-W:correspond to with normal faults structures.
Study of the general characteristics of Fractures in the central part of
the AL-Kabir AL- Shimali river basin showed the presence of
several main groups of Fractures with directions NE-SW _ NNESSW,
NW-SE , E-W.and showed increased fracture rate in
the
northern and southern parts of the study area, and that the spacing
between the Fractures close to the medium convergence (5-34) cm ,
also show a aperture ranged between (0.1-5.1) cm, where aperture
width was increased in southwest of Lake 16 October near Lattakia-
Kless fault .
The landslides and avalanches formations represent serious
danger on the constructions. They interfere with Tectonic conditions
to constitute a constructive system in some cases. Therefore appear
the importance of this study, which focused on the
tectonic role of
these phenomenon in Al Bassit area, NW. Syria, where different
deposits, mostly volcano- sedimentary of Ophiolitic complex. The
field executed studies and their analysis have permit to determine
the lithological and tectonic factors which have affecting the region.
Also the study of slope slip and characterizations have been studied
and an important comparative tables are proposed to study globally
and locally these landslides, and serve as a model for future studies
to prevent the risks of these slips.
