يهدف هذا البحث إلى تحديد منشئية الصخور البازلتية في عدة مواقع من رقعة القدموس من خلال دراسة تنوعها البتروغرافي وتراكيبها الكيميائية، باستخدام كل من المجهر المستقطب لدراسة الشرائح الصخرية وجهاز X.R.F للتحاليل الكيميائية. حددت الدراسة ثلاثة أنواع بتروغرافية من البازلت القلوي اعتمادا على فلزات الفينوكريست التي تزيد نسبتها عن 5%. تطابقت التنوعات البتروغرافية المحددة مع تراكيبها الكيميائية المتقاربة نسبيا.ترتبط الصخور المدروسة بمهل بازلتي متوسط القلوية إلى قلوي، من النوع الصودي - البوتاسي بمغنيزية(Mg) بين 28-43%، تمثل البركنة في منطقة الدراسة نموذجا لبركنة داخل الصفيحة، مرتبطة بتكتونية انهدام الغاب.

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 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.
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.
