رست 11 عينة من الرمال الشاطئية لمنطقة جنوب طرطوس باتجاه شمال جنوب نقريبا و بمسافة حوالي 15 كم، تم تحديد 27 نوعا من هياكل المنخربات الموجودة فيها، أغلبها كان قاعيا مع سيطرة ملحوظة للهياكل البورسلانية. يزداد غنى هذه الرمال بهياكل المنخربات مع الاقتراب من خط الشاطئ، كما أن الرمال الناعمة البعيدة عن خط الشاطئ أقل غنى بهياكل المنخربات من الرمال الخشنة الأقرب إلى الشاطئ، و هذا يعود إلى فعل التجوية الذي يشارك فيها عمل الرياح بشكل فعال، حيث يتم تحطم و تكسر الهياكل نتيجة لذلك. إن مثل هذه العمليات الجيولوجية الحالية يمكن إسقاطها على الزمن الجيولوجي السابق لاسيما البليستوسين، حيث توضع الحجر الرملي بعمليات جيولوجية مشابهة لما يحدث في العصر الحالي.
Eleven Samples of costal sand was studied, nearly south- north along 15 km ,27 Spcieses of Foraminifera Testes was determined (founded)in it, most of them was benthic , but the porcelanic testes were more commen. This Costal sand is richer in Foraminifera Testes near the costal line. As well as the fine far costal sand less richer in Foraminifera Testes than the coarse sand which is near of costal line, because of the effect of weathering , which the Aeolian processes very clear in it. And this causes brokig the Foraminifera Testes. The recent geological processes can be reflex at the past geological time, especially for sand stone in Pleistocene Age. This sandstone deposit by geological processes seemlywhat happing in our days ( recent).

The lithological study and micropaleontological analyses of 21 samples
taken from four geological sections of lower Miocene deposits led to a
stratigraphic study for determination of enrichment of planktonic species in
these deposits . These speci
es were combined with biozones of lower miocene
and their stratigraphic distribution in the studied sections according to
planktonic foraminifera of worldwide spreading . This study contributed in
understanding of paleogeographic development of Neogene basin within this
period of time , which appeared as a marine progress in lower Miocene ,
which continued up to upper Miocene in the northwestern part of Syria . The
sediments of lower Miocene consisted of marl , clay marl deposits with
interfacial layers of clay and limestones or marl limestones deposited
unconformithy with nummoliticlimestones of Eocene , or cretaceous
carbonates rich in betome sometimes .
This paper Introduces a clear idea about marine and coastal
biodiversity of crustacean zooplankton and its quantitative and
qualitative monthly variations and its relationship with the changes
of some of the main environmental factors such as temperature,
salinity,dissolved oxygen, transparency and pH.
Some magnetic and physical properties ( magnetic susceptibility , intensity
of remanent magnetisation , ac current electrical conductivity and density ) of
١٨١ samples from ٣٠ sites of Middle Miocene basaltic rocks (β 1
N2) from Al-
Kisweh region
south of Damascus were studied, in order to extend the previous
study ( Abou-Deeb, ١٩٩٧) to other regions so that these properties might be
used as characteristic factors in discriminating the neighbouring basaltic flows
.The measurement of the in situ magnetic susceptibility of ٧٥ basaltic sites ,
distributed on ٨ localities , in the region helped to calculate the mean value of
the magnetic susceptibility of each locality and an overall mean value of the
whole region, which might be used in any magnetic interpretation of the
magnetic anomalies. Also, the density of ١٢٨ samples were measured and a
mean value of the density of each locality and an overall mean density were
calculated in order to be used in any future interpretation of any gravity
anomaly in the region .
This study was conducted to evaluation of some marshes soil physical
characteristics at south Iraq from studying soil properties and accounting the
simple and multiple correlation coefficients and relation equations, from which
we can predicted th
e soil aggregate stability modules of rapture and soil bulk
density. Three transacts were chosen, which cover all south Iraqi marshes, with
selection of the larger marshes at every transect. The transects are: First
toward Amara included marshes of Al-Msendak, Al-Saadiah and Al-Wadiah.
Second toward Al- Nasiriah which included the marshes of Delmag, Ghumugaa
and Al-hammar. Third toward Samawa which included the marshes of Al-
Ramah and Lafti.
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.
