يقدم هذا البحث دراسة جيولوجية حقلية و بتروغرافية للصخور البازلتية في ( خربة السنديان ) و التي هي جزأ من الأنابيب الانفجارية لجوبات منطقة القرداحة التي تقع في السلسلة الساحلية الموازية لانهدام الغاب, حيث تم من خلال البحث التعرف على أنماط و نوعية الصخور البازلتية الكريتاسية و الصخور البازلتية النيوجينية (N2b) في منطقة البحث.
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.

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 study deals with the basaltic rocks spread in Sheen Volcanic
Hill. Where the studies have signified that these volcanic eruptions
are an extrusive emergences, come from Sheen Barsheen Volcano,
which Were poured as basaltic casts of declinatio
ns towards the
east, separated by lateritic separations, date back in origin to the
end of late Miocene- Pliocene of big thicknesses near the rifting
line, over 800 m, thick.
Study of basaltic rocks in the Rastan region showed the presence of
many morphological and petrographic varieties compatible with
rocks of Alhesen castle region. Chemical analyses of studied rocks
proved to be alkaline rocks with sodic-potassic na
ture. Rotten parts
of studied rocks considered an important source of civilian
installations, paving roads, and as materials for manufacture of
cement, in addition to their academic importance in Petrological,
paleogeographic, and tectonic studies.
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.
In this work we studied the Syrian Ophiolite complex rocks.
like (ultrabasic: Dunite ,Peridotite- Hartzbergate) and the sedimentary
rocks like Radiolarite,that at the west end of ALKABER AL SHIMALI
river, by collecting field samples and mapping of
geological section.
This study gave us a detailed Petrographic and metallic describe of
rocks in the study area, in this study see the installation of rocks and
multiple stages of transformation of metals ,and indicated the presence
of iron and manganese oxides.
