تتميز الصخور البازلتية في موقع السفرقية (منطقة القرداحة) بتماسكها و مقاومتها و تتألف من الأسفل الى الأعلى طف بازلتي بركاني شديد الفساد و بازلت فراغي متوسط القساوة إلى قاسي (رمادي) و تحوي الفراغات في أغلبها نواتج التجوية مواد غضارية و كلسيه يليه بازلت كتلي مصمت ذو قساوة عالية له بنية بلورية ناعمة - رمادي مسود . يتكون البازلت بتروغرافياً في هذا الموقع من بازلت أوليفيني مصمت، بازلت أوليفيني فراغي، بازلت أوليفيني أوجيتي مصمت، بازلت أوليفيني –بلاجيوكلازي، بازلت أوليفيني أوجيتي مصمت، بازلت أوليفيني أوجيتي فراغي، بازلت، بازلت بلاجيوكلازي فقط في الشريحة S14. و صخور بيروكلاستية: لابيل أوليفيني مصمت-لابيل أوليفيني – بلاجيوكلازي – لابيل بازلت أوليفيني-أوجيتي.
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.
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.
Palaeomagnetism and some magnetic and physical properties such as
magnetic susceptibility, intensity of remanent magnetisation, ac current
electrical conductivity and density for the number order (٣٩ - ٥٤) of samples
from ٩ sites of Upper Pliocene
basaltic rocks from the area west of
Homs were studied. The aim of the works to extend the previous studies (Abou-
Deeb, ١٩٩٧a, b) to other regions so that these properties might be used as
characteristic factors in discriminating the basaltic flows.
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.
