Geomorphological-chemical studying of hole phenomenon which
taked place in KARKIT village (NE of Lattakia) at 11/2/2009,indicate that it was a result of karstic phenomenons in gypsum rocks,this karst is result of underground water drainage inaccordance with fissures direction In study region N025 .
A geological geophysical study was carried out to determine positions of gypsum Messinian (seismic reflector) at different depths on land (eastern Lattakia) and under the seabed of western Lattakia During Messinian the tectonic action changed Med
iterranean Sea to evaporated basin.
Northwestern Syria was affected by salinity crisis because sea water regret from it and due to that it formed lagoons.
The establishment of geological sections allowed to determine reflector surface and gypsum positions by linking geological sections on land to marine seismic profiles and correlating it with drilled wells in Lattakia and seismic unites determined by (Hall et al., 2005).
An available free groundwater were classified
hydrochemical, and determined its fitting for general uses in a part
of Damascus's Ghouta, which suffers water deficiency, where the
study carried out on groundwater samples taken from 20 wells
distri
buted on all study area, the results show that groundwater
classified hydrochemical as calcic water and non potable, and
unsuitable for domestic consumption in broad part from study area,
but arable and recommend to use in irrigation plants that have weak
resistant to salinity, and not preferable to use in industry generally,
but it's good for building and concrete works.
The study of continental Neogene deposits in Damascus and Kalamoun
areas has led to distinguish two lithological formations: the bottom one is
composed of debris with fine elements in general, dominated by sand and clay,
widespread on its base loc
ally remnants of volcanic basalt flow. The top
formation consist of conglomerate sediments with coarse elements of mixed
sizes and sources.
The study showed that volcanic flow which came from the south as basaltic
flow from Al-Manea Mountain to the south of Damascus, reached the southern
part of Dimas Basin and not far beyond it towards the north.
Also, the study demonstrated that the age of the continental deposits
overlying the volcanic flows belong at their bases to Lower Miocene age, in
comparison with the data of the isotopic analysis of the volcanic rocks
previously recorded in the region.
All the well logging reinterpretation by using the new softwares, cores
analysis and results of seismic 2D and 3D surveys allowed to identify the
reservoir characteristics of Kurachina Dolomite Formation of middle Triassic,
for two zones (C2, D1)
in Jihar field and its affect on hydrocarbon potential in
this area.
It's found that C2 reservoir consist mostly of dolomite and small amount of
shale and anhydrite, fractured and all the fractures are full of organic
materials, calcite, anhydrite, silica and little amount of stilolite, while there is
succession of limestone and fossil remains, in some places there is shally
dolomite. Whereas D1 reservoir is mostly crystalline limestone and the
fractures filled with dolomite.
The Palmyride mountain chain is the main structure in central Syria. It
represents an intracontinental NE-SW trending fold belt, within the northern
part of the Arabian Plate. It is bounded by the Aleppo–Mardine uplift to the
North–West and by the
Hamad Uplift to the South-East.
This study is based mainly on numereous field geological observations. New
informations are obtained about the tectonic behavior of the Palmyride fold
belt. The main faults are generally normal. There is no surface geological
evidence for thrusting within the Palmyrides, as suggested by the authors
before.
The argument to be developed in this study is that the Palmyrides fold belt
owe its existence to the lateral displacement of the Triassic gypsum, not to the
lateral decollement of its overlying series, and consequently no shortening of 20
km as estimated by the authors before.
A simple model is proposed to explain the observed tectonic features. It is
interpreted that this tectonic event induced a master transfer of the Triassic
gypsum under the Arabian Plate movement toward the north and the northeast
at the Neogene time.
The Rudist Vautrinia syriaca (VAUTRIN) was considered so far as
characteristic of the Maastrichtian of the northern margin of the Arabian
platform, but new research shows that it is not possible to retain this
consideration. Indeed, in both types
localities (J. Abd Al Aziz and Yeyla) this
rudist is present in breccia. The biostratigraphic analysis of the environment in
the first locality can assign a Campanian age or precampanien age.
The study demonstrated also that the presence of the Rudist Vautrinia
syriaca (VAUTRIN) within breccia and conglomeratic sediments above the
ophiolitic complex in the north-west of Syria (Al Bassite - Yella hill) shows that
the ophiolite emplacement along the northern Arabian Platform has happened
in the Campanian time or in Precampanian time and not during the
Maastrichtian time.
The presence of huge blocks of ophiolite on the surface of the Turonian
limestone layers near Saarinjek village in Afrin Mountains (Kurdag) confirmed
that the ophiolitic complex emplaced on the edge of the Arabian Platform at the
end of the Turonian / early Coniacian, and not during the Maastrichtian.
The obduction of the ophiolitic complex explains the big marine
transgression on the Arabian Platform since the beginning of Senonian.
The authors’ works concern the sediments of the upper part of Tortonian
within the basin of El Ma Labiad located at the southern part of Tebessa city,
belonging to the eastern saharian Atlas mountains chain on the Algero-
Tunisian borders.
The se
dimentological analysis, carried out on 120 samples, has confirmed a
downlap development structures towards the West of the basin. These analyses
have also proved the presence of a detrital continental sedimentation of four
environments characterized by the river, delta, lake and marsh materials.
The petrographic and morphological analysis reveal a clastic sediments
essentially quartz-bearing interbedded by some argillaceous intercalations, and
a far-off water transport of an origin probably saharian.
The present work is concerned with studying and analyzing the satellite
imagery to extract and integrate lineament by using logic operator technique
(Baridi J., 2000), in turn of lineaments analysis and interpretation to clarify the
general struct
ural framework of the south eastern part of Sinai which have
complex tectonic. This study revealed that there is sort of tectonic rotation,
affecting the area in clockwise direction. Accordingly the tectonic activity
seaward is believed to be stronger than that landward, i.e. the stability in the
zone behind the shore line is less than that in the land side. Since the tectonic
activity in the study area comes from sea towards land, along an E-W direction,
the Gulf of Suez tectonism is suggested to effect the study area, where the
tectonic activity decrease from N to S. The surface activities i.e. (erosion)
decrease toward the north, south and shore line of the Gulf basin more than
that at its middle part. The tectonic activity in this study classified according to
the lineaments thickness to reveal the shallow, intermediate and Deep seated
tectonic.
The inclined shear restoration technique was used in this research as the primary
method to remove the effects of fault displacements. These displacements were resulted
from the impact of the NE-SW trending extensional forces. The inclined shear re
storation
technique was applied to the NE-SW trending seismic section (Inline A2157) along the
Elward Area, using 2D move software.
The vertical shear restoration technique was used as a complementary method to
remove the effects of folding associated with faulting, especially to formations under the
Base Upper Cretaceous Unconformity (BKU).
The inclined shear and the vertical shear restoration techniques contrib uted to build
many geological sections according to depth seismic section (Inline A 2157). These
sections showed the Tectonic setting of the study area from Upper Ordovician till current
time.
