تم توصيف التوضعات الحاملة للزيوليت في منطقة بانياس عن طريق دراسة العينة A ( و هي مزيج على شكل مسحوق لعينات من خمسة مواقع مختلفة من مستويات طفية و طفيتية متباينة ) و مقارنتها مع العينة B (المأخوذة من موقع بساتين الأسد ضمن منطقة الدراسة). أظهرت نتائج قياس انعراج الأشعة السينية بطريقة المسحوق XRD وجود عدة أطوار فلزية زيوليتية، بالإضافة إلى فلزات غير زيوليتية و زجاج بركاني غير متبلور. أظهر طيف الأشعة تحت الحمراء FTIR سمة عامة للمجموعات الزيوليتية. بيّن التحليل الحراري التفاضلي DTA ثباتاً ضمن حدود استقرار البنيات الزيوليتية. حسبت المساحة السطحية النوعية بطريقة BET و أعطت القيمة 87m2 ⁄g، كما حسب مجال توزع حجم المسام و كان بحدود 40Ǻ، و متوسط قطر المسام بحدود 23Ǻ. أظهرت دراسة العينة المرجعية B بطريقة الـ XRD وجود أطوار زيوليتية مختلفة إلى حد ما عن العينة A. بيّن طيف FTIR سمة عامة لما تبديه المجموعات الزيوليتية. تبيّن من خلال منحنيات DTA ثبات حراري عالٍ للعينة B ، و مساحة سطحية نوعية بقيمة 61m2 ⁄g، و توزع حجم المسام ~40Ǻ، و متوسط قطر المسام في العينة بحدود 25Ǻ.
Zeolite bearing deposits were characterized in Banyas region using sample A (which is a powdered mixture taken from five tuff and tuffite levels) compared with sample B (which is taken from Basatin Al-Assad site within the studied region). XRD method showed several zeolite phases in addition to non-zeolite minerals and volcanic glass. FTIR method revealed a general feature of zeolite groups. DTA method showed a range within zeolite structure stability. Specific surface area was measured using BET method giving the value 87m2/g. The range of pore volume distribution was also calculated with ~40Ǻ, and intermediate pore diameter of ~23Ǻ. XRD study of the standard sample (B) showed slightly different zeolite phases from A. FTIR measurement showed same results as in A. DTA plots revealed a high stability of sample B, SBET of 61m2/g, VP around 40Ǻ and r- at ~25Ǻ.

This study aims to identifyzeolite phases within the sedimentary-volcanic deposits in Banyas region because of their scientific and economical interest. A group of samples chosen from different sites in the region were studied using X.R.D instrument
with X-powdersoftware. The studies samples were divided into three groups: Igneous, sedimentary and zeolite deposit groups. zeolite deposit, in turn, were put in two subgroups: a new zeolite and already known zeolite subgroups in other regions in S.A.R. The results of this study are quite new in Banyas region.
In this research, the natural pyrite ore found in Tartous Governorate was described by studying the two samples taken from Hosn Suleiman -Safita (A) and Al Qadmous (B) area, in addition to studying the optimum conditions for pyrite dissolution (pH -
time - quantity) with aerobic conditions.
The results of X-ray diffraction (XRD) showed that the sample (A) is mainly composed of pyrite mineral and does not contain impurities, while sample (B) is composed of pyrite mineral combined with a small amount of calcite mineral, and these results were confirmed by the result of (FTIR) infrared spectroscopy and Polarised light microscopy (PLM(. The iron percentage in the two samples (A,B) is ranged between (42.6 – 43 %) and the sulfur percentage is between (40 – 53.7 %).
With regard to pyrite dissolution, the results showed that pyrite taken from Hosn Suleiman (A) begins to dissolve at pH values less than 4.5, and the contact time is about 6 hours. By Comparing the results of sample (A) with sample (B), we found that the dissolution of sample (A) was about three times less than the dissolution of sample (B), and this is due to the fact that sample (A) contains pure and well crystallized pyrite ore while sample (B) contains pyrite combind with calcite, which increases its solubility.
Composition and origin of barite ores studied in Qerdaha
region. The fieldwork was done on geological sections belong to
Maastricht, from which many nodules like specimens were taken.
Both mineralogical and chemical composition of the
specimens w
ere determined using XRD. Petrological study was
done, as well.The mineralogical composition of most nodules
consisted of barite-calcite of various percentages. The nodules at
northern part of studied region consisted of barite or barite-calcite,
turned into calcite or calcite-barite phases towards south.
This study aimed to investigate the characteristics of soils developed on volcanic ash in an area with a Mediterranean soil moisture regime to determine the presence or absence of amorphous minerals in these soils.
The study was conducted in four sites belonging to the Sheikh Badr district in Tartous
province. Ten different types were identified according to international standards. During
the 2016 and 2017 growth seasons, readings were recorded for phenotypi
c parameters as
well as physical and chemical analysis of fruit clusters. The studied types differed in many
characteristics. The results of the cluster analysis showed the distribution of the studied
types in two groups with a variance of 93%. The mean weight of the cluster varied
between the medium (349 g) and the large (1140.45 g). The ratio of total dissolved solids
(TSS) between the low (12.75%) and high (18.82%). the acidity between the very low
(3.53 g/l) and medium (6.38 g/l).
