قدمت الدراسة الليتولوجية و الباليونتولوجية لتوضعات النيوجين البحري في منطقة سـلقين (شـمال غرب سورية) معطيات جديدة سمحت بتمييز عدد من الوحدات الليتوستراتغرافية و تحديد عمر كل منهـا، الأمر الذي أتاح إجراء ترابطات ليتوستراتغرافية دقيقة في منطقـة الدراسـة و بينهـا و بـين المنـاطق المجاورة، وصولاً إلى معرفة التطور الجيولوجي لهذه المنطقة خلال دور النيوجين. و قد أظهـر التـوزع الستراتغرافي للمنخربات العوالق (البلانكتونية) في المنطقة توافقاً تاماً مع ما هو معروف خلال النيوجين في مناطق أقيانوس التيتس. و قد سمحت المقارنة مع هذه المناطق بتأكيد وجود ثغرة سترتغرافية مهمـة في منطقة سلقين شملت أزمة الملوحة التي سادت مناطق البحر الأبيض المتوسط خلال الميوسين الأعلى (غياب طابق المسينيان).
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 lithostratigraphic 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 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.
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.
Field study of the basalt rocks indicate in Jaubet-AL Dilbe that casts basalt in the
field consist of tuffit, pyroclastic Sometimes consist of porphyric coarsebasalt with lava
structure and brescia of tufa ,which contain a lot of surrounding rocks
as lime stone and
dolomite. The basalt mass noting the presence of dykes in search area incisor squad
pyroclastic. The basalt color is light gray to dark gray. It is form the following
petrographical kinds: olivine basalt, olivine augite basalt, olivine plagioclase basalt,
plagioclase basalt. As for the lapilli consist of basalt (olivine basalt olivine vascular basalt
and plagioclase basalt)
This paper Presents a Petrographic and geologic study of basaltic
rocks in( Hrbet AL-Sindian). which is part of the Diaeremes to the
plosirelacune Qardah district .In study, We identify the type of
Cretaceous and Neogene basalt rock in the studied
area.
The Research In This Regard Is Concerned With Pollution Of The Marine Environment, Which Is One Of The Vital Topics That Have Occupied The Attention Of The International Community In General and Coastal State
s In Particular, For Which The Conventions Aimed At ProtectingThe Marine Environment Were Concluded By Adopting The Rules Of Substantive Responsibility For Damages Resulting From Marine Pollution Accidents, Which Has Proved To Be The Legal Valve To Guarantee Individuals' Rights And Facilitating Compensation For Damages Resulting FromPollution Of TheMarine Environment In Cases Where AggrievedIs Unable To Prove Fault In The Face Of Responsible. The Research aims To Briefing By PillarsOf Substantive Responsibility And The Implications Of establishing It In The Light Of International And Regional Conventions That Concern The Issue Of Pollution Of The Marine Environment.The Research concluded That The Implementation Of The Substantive Responsibility Rules will Achieve Greater Protection For Those AffectedIf The Period Of Limitation Extinguished For The Compensation Lawsuit Is Taken Into Account In The Interest Of Aggrieved, Especially Since Some Conventions Don’t TakeInto Account That The Environmental DamageIs Slow To Emerge, Thus Losing The Right Of Aggrieved To Compensation Due To The Lapse Of Time
