درست المغنطيسية القديمة لـ 44 موقعاً من بازلت البليوسين الأعلى من المنطقـة الغربيـة و المنطقـة الشرقية المحيطة بالفالق المشرقي في منطقة البقيعة الواقعة إلى الغرب من حمص. مكن التنظيف المغنطيسي للمغنطيسية القديمة من عزل مركبة مغنطيسية أولية في معظم المواقع. و تبين وجود جميع أنواع القطبية مـن نظامية، منعكسة و متوسطة مع غلبة القطبية المنعكسة. و قد أهملت المواقع ذات القطبية المتوسطة و تم عكس اتجاهات المغنطيسية للمواقع المنعكسة.
44 sites were sampled from the Upper Pliocene (βNb 2) basaltic flows, from the western flank and the distant eastern flank of the Levant Fault in the Buqeia area NW of Tel Kalakh and west of Homs. Thermal demagnetization led to the identification of consistent directions of remanence in most sites. Normal, Reversed and Intermediate polarities are identified, with Reversed polarities dominating. The Intermediate polarity sites were excluded and the mean directions of the Reversed sites were reversed.

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 Palmyride mountain chain is the main structure in central Syria. It
represents an intracontinental NE-SW trending fold belt, within the northern
part of the Arabian Plate. It is bounded by the Aleppo–Mardine uplift to the
North–West and by the
Hamad Uplift to the South-East.
This study is based mainly on numereous field geological observations. New
informations are obtained about the tectonic behavior of the Palmyride fold
belt. The main faults are generally normal. There is no surface geological
evidence for thrusting within the Palmyrides, as suggested by the authors
before.
The argument to be developed in this study is that the Palmyrides fold belt
owe its existence to the lateral displacement of the Triassic gypsum, not to the
lateral decollement of its overlying series, and consequently no shortening of 20
km as estimated by the authors before.
A simple model is proposed to explain the observed tectonic features. It is
interpreted that this tectonic event induced a master transfer of the Triassic
gypsum under the Arabian Plate movement toward the north and the northeast
at the Neogene time.
a new benzyl triterpene was isolated from the aerial parts of Erica
verticillata. The structures of the compound was established as 10-
benzyl-2,2,6a,9,9,12a,14a-heptamethyldocosahydropicene-4acarboxylic
acid.
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.
The study showed that We can Processing of a new pleasant nourishing drink from
carob seeds, by roasting the fresh seeds of Carob at 200C° for 2 min .
The results of sensory tests and test taste according to international quality
standards ISO8588
7: 2005 at samples drink prepared from seeds roasted at different
temperatures and times showed that the sample prepared at 200C° for 2min is the best, also
the results of chemical analysis for powder of roasting carob seeds at 200C° for 2 min that
used in prepare the drink showed that it has a high nutritional value because of its high
content of protein 19.8% and fiber 12.9%, low content of fat to 1.6% and sugar to 1.5%,
and completely free of caffeine, therefore, it suitable as a healthy and nourishing drink for
patients with heart and diabetes disease. The manufacture of this drink is economically
