تعد صخور الكريتاسي الأعلى لتركيب كراتشوك المتمثلة بتشكيلتي الماسيف ، و الشيرانيش هامة لخزن النفط و الغاز، فهي تعتبر من أهم المكامن النفطية في سورية، حيث دُرست (25 عينة) من التشكيلتين . تكون تشكيلة الماسيف ذات مواصفات بترولوجية جيدة كصخور خازنة ، و منتجة من حيث كونها مؤلفة من صخور كلسية مسامية جيدة و مشققة ، و منتشرة في كامل الطية ، أو تركيب كراتشوك . أما تشكيلة الشيرانيش فهي متجانسة ليتولوجياً و مؤلفة من تناوب الحجر الكلسي الغضاري و المارلي الغني بالمنخربات ، حيث تم تقسيمها إلى ثلاثة نطاقات تبعاً لمواصفاتها البتروفيزيائية ، فالنطاق العلوي هو الأكثر تشرباً بالنفط من النطاقين الآخرين ، مما يدل على وجود مؤشرات من توفر المواصفات الخزنية لهذه التشكيلة.
The Upper Crétacé rocks of Krashok formation, Massive formation and Shiranish formation, are very important for petrol and gas reserve, where it is the importance petrol reserves in Syria. 25 samples of these two formations werestudied.The Massive formation had a good Petrological character as reserves rocks ,where it contain calc rocks, which have good reserving properties, and it cover the hole area , and it contain a petrol. Where the Shiranish formation is almost homogenies, and contain calc-marl-clay rocks with foraminifera, and it divide into three zones, depending on it is petro physical properties, the upper zone is the most absorb of petrol, by comparison whit others zones, which show there are many indicators reserve characteristicin these formation.

Shiranish formation in Sazaba Oil fields region had been divided by
Petrology study and well Logs measurements to three major members (lower –
middle – upper). Then these members have been divided to lithostratigraphic
units and subunits. This stu
dy showed that the lower member is formed of
clayey - limestone rocks rich in planktonic foraminifera and glaconitic sand.
The middle member consists of organic limestone facies, dolomitic-limestone,
sometimes clayey - limestone rocks with crystals of pyrite and glaconitic sand.
Organic- limestone rocks and detrital limestone are predominant in the upper
member interbeded by dolomitic-limestone and rare clayey – limestone. This
facies contains pelagic and planktonic foraminifera.
The role of diagenes phenomenon is evident on Shiranish’s facies through:
dolomitization according to burial and miksing processes. It is also clear
through chemical compaction, mechanical compaction, cemenation,
micretisation and silisification.
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.
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 Kamshoka formation in Al-Rasafa basin is the second reservoir , because it has
a petroleum importance, where these formation have not petrol in Syria exception in Al-
Rasafa basin, where the fracture calk rock , and dolomite contain a good amou
nt of hairdo
carbonate, so it gave the importance of. Theaim of these research is to do petro logical,
and geneses analyses ofKamshoka formation, and to estimate the storage characters , and
define characters , and kinds and porosity of fracture calk rock , and dolomite, and to
have conclusion about the conditions, and environments of sedimentation, and the stages
of sedimentation development for the all area. The Kamshoka formation showed a good
productivity in some holes which was drilled brand-new, and it gives a hopes to new
discovering in another areas in Syria .
