قادت الدراسة التي أُجريت على توضعات النيوجين القارية في كل من منطقتي دمشق و القلمون إلى تمييز تشكيلتين ليتولوجيتين: تشكيلة سفلى مؤلفة من رسوبات حطامية ذات عناصر ناعمة بصورة عامة، يغلب فيها الرمل و الغضار، تنتشر في قاعدتها محلياً بقايا صبة بركانية بازلتية؛ و تشكيلة عليا مؤلفة من رسوبات كونغلوميراتية ذات عناصر خشنة متباينة الحجوم و المصادر. بينت الدراسة أن الصبات البركانية التي اندفعت من الجنوب، كصبة جبل المانع البازلتي في جنوب دمشق، بلغت الأطراف الجنوبية لحوض الديماس و لم تتعداها بعيداً نحو الشمال. كما بينت الدراسة أن عمر التوضعات القارية المستقرة فوق الصبات البركانية تعود في قواعدها السفلى إلى عمر الميوسين، و ذلك مقارنة بمعطيات التحاليل النظائرية للصخور البركانية المسجلة سابقاً في المنطقة.
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 locally 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.

The lithologic and palaeontologic study of the marine Neogene in Salquine
area (NW Of Syria) gave new data which allowed the distinguishing of a
number of lithostratigraphic units and the determination of their ages. This led
to precise lithostrat
igraphic correlations between the studied area and the
neighboring areas, and finally a clear knowledge of the geological evolution of
the area during the Neogene. The stratigraphic distribution of the planktonic
foraminifera in the area showed a perfect agreement with what is known
during the Tethys Neogene. The comparison with the neighboring areas led to
the discovery of an important stratigraphic lacuna in Salquine area during
salinity period of the Upper Miocene of the Mediterranean region.
The atrical activity is part of the school of modern school curriculum.
It helps in the formation of habits, skills, values and practices needed to
continue their education and to participate in the overall development,
hence the importance and ef
fectiveness of the school stage in the
upgrading of the collection of the first students of basic education in each
of the Sultanate of Oman and Syria, the study aimed to identify the
students to the world around them and educate students and the Arab
heritage, history and culture defines the lives and problems of others, and
the upbringing of the students on .
This study was conducted in two areas: Misyaf in Hama governorate and
Alshaikhbader in the governorate of Tartous to identify some of economic and
social effects of animal production projects carried out by rural woman who
had a loan for it. The p
rimary data were collected during the period 2012-2013
from a random sample (23 villages in Misyaf, and 13 villages in
Alshaikhbader). Size of the sample was calculated according to Morgan law so
that 243 rural women were valid for analysis. The results showed a high
percentage of successful projects which had an economic and social impact for
91.8% of respondents and these projects had the following effects: 57.2% of
targeted families stated that there was a rise in their spending on food, 92.2%
of them confirmed the improvement of their food quality. Enhancement in
quality and quantity of their clothes and increasing their ability to take family’s
related decisions declared by 61.7% and 44% of respondents respectively.
About 90.5% of rural women were able to make project’s related decisions and
85.6% of targeted women acknowledged a rise in self trust after the
implementation of the project. The results also showed that there was a
significant relationship between each of employment status before having the
loan, project’s annual income and the dependent variable: rural woman’s
successful project (at level of significance 1%) by using Logistic Equation. It
was concluded that micro finance projects had a good impact on empowerment
of rural women and activating their economic and social role. The projects also
increased the family income and improving the living situation.
The aim of this study is to use the measured values of the magnetic
susceptibility in the classification of the basaltic rocks and their different
differentiation degrees as an additional discrimination factor to the
geochemical analyses, which we
re applied on the basalts of southern and southeastern
Syria. So the magnetic susceptibility of ٢٠٤ specimens sampled from all
the ٧ basaltic groups in Qasr Shbeeka area in addition to ٦٢ specimens
sampled from three groups from outside the studied area were measured. This
led to the determination of all the magnetic susceptibility ranges, their mean
values and their standard deviation of the basaltic rocks in the area.
The eddies at the Egyptian and the Middle East coasts are generated by the instability of the surface circulation (AW: Atlantic Water). For describing these eddies, a lot of satellite images (SST: Sea Surface Temperature) have been treated and analyz
ed at the Levantine sub-basin. This study inferred that there is an approchement in the eddies´ trajectory in both south west and south east of the Levantine sub-basin, where most eddies tend to separate from AW towards off sea. While eddies in the south east of the Levantine develop faster than that in the south west.
