Kopet-Dagh basin is located in north and northeast of Iran. Khangiran Formation is one of the most importantformations of Paleogene deposits. For study of Khangiran Formation, Chehelkaman Syncline section wasselected. This section located in southwest of Sarakhs city, east of Kopet-Dagh basin. Thickness of this section is136 meters and lithology of this section composed alternation of olive green Marl and limy yellow Marl. In thisresearch foraminifera fauna of Khangiran Formation was studied. The age of this section is Early-MiddleEocene, and planktonic foraminifera fauna of this section shows anomaly. Based on this anomaly, lack ofMorozovellids, that are index fossils of Eocene, was observed. Eutrophic condition of this Formation as for theplanktonic and benthonic foraminifera study is the reason of this subject that it's the result of changes in thepaleoceanographic conditions such as situation of stratification of water column and nutrient changes. As far theMorozovellids can't accordance with eutrophic condition, lack of the species mans of this genus observed forKhangiran Formation. Khangiran Formation condition is comparable with Caucasus basin and this subject can beindicating of same condition of this two basin at least during the Eocene time. Manuscript profile

Considering the economic importance of this region, for the first time some studies on superficial sediments(deposits) foraminifera were carried out in this region. Purpose of these studies was to investigate effect ofenvironmental changes on foraminifera and to use them as bio-indices in diagnosis of contaminations. In thestudies regarding foraminifera, 12 genus and14 species were identified and foraminifera with hyaline lime shellhad the greatest frequency. The main identified collection is: Ammonia beccarii Linne.And the speciesaccompanying this collection are: Amphistegina lessonii, Elphidiom crispum, Elphidiom craticulatum,Triloculina tricarinata, Quniqueloculina seminulum, Ammonia parkinsoniana, Eponides repandus, Dendritinaambigua After foraminifera with hyaline lime shell, foraminifera with selenosis progeny shell were ranked nextin terms of frequency. However, foraminifera with agglutinated shell were not observed in this region. Ingeneral, the obtained results from mineralogy studies on deposits of the ebb and flow area is the evidence thatmajor part of the sediments are related to continental environment of the detrital deposit type. In sectionecological studies, water's physicochemical factors are measured. Based on these studies, increase of water'stemperature and salinity results in decrease of solution oxygen in water and water's acidity degree. However, ingeneral, water's acidity fluctuation is slight and insignificant. The most important physicochemical factoraffecting development of foraminifera is amount of solution oxygen in water which controls their frequency anddiversity. Precipitation of oil carbohydrates and other contaminators produced by petrochemical activities in theregion ruins the bio-environment, reduces solution oxygen, and gives rise to release of heavy and toxic metals(mercury and lead) from solid state to liquid which leaves numerous negative effects on marine andenvironmental ecosystem Manuscript profile

Ghir-Karzin city is in the southeastern Fars province. In this research by using satellite images, length ongestionmap, cross section, and number of lineation and map of the earthquakes focus in the region were prepared andthen by obtaining indices of mountain’s Facet outcrop amount (in percentage), mountain’s facet meander (Smf),and length-stream index (SL) on the three anticlines Changal, Palang and Afzar, of tectonic activities rates ofthese anticlines have been investigated. The results obtained from these indices, in addition to being presented inthe tables, for much better representation and analysis, have been shown as a numerical model and a profile aswell. . Combination of the obtained data from the map of fractures, indices’ numerical model, map of epicenters,and drainage profiles indicates that the region’s anticlines are active, i.e. uplifting rate in the region is higher thanerosion rate. Finally, after study of the obtained results, the reason for high rate of tectonic activity in the easternsection of Changal anticline was found to be this anticline’s vergency towards south-west and increase of thefissure and fractures as a result of extensity in the northern top chord and pressure production in the southern topchord. In the western section of this anticline too, the high tectonic activity can be attributed to presence of theDarre siah Fault. High tectonic activity of Afzar anticline is due to presence of the active fault Ghir in north-eastof this anticline and the anomaly map of the fractures and epicenters confirm these results as well.

In terms of water quantity and quality is the most important part of an ecosystem. Reduced both the quantity andquality of water in a large negative impact on ecosystems and biodiversity threaten leaving Natural food sourcesand effects on organisms and causes irreparable damage, Knowledge and information about water rights and theapplication of specific rules to regulate the management macro environment seems essential. Therefore, based onthis study on the lake among the largest watershed of the country is carried out in terms of locationgeographically in northwestern Iran between East Azerbaijan and West Azerbaijan longitude 44 degrees 14minutes to 47 degrees 53 minutes east and 35 degrees 40 minutes north latitude to 38 degrees and 30 minutes islocatedThe main reasons for studies on slow dry lake-level changes in temperature and precipitation in theregion of 79-83 were studiedAnd consequently the rate of temperature change is not so drastic drop in waterlevel can cause dry lakes and rainfall of 79-83 years of upward growthDuring the same period, but the waterlevel of the lake has suffered a significant drop. Check water level fluctuations indicates that in 1346 the lowestlevel to the height of 1273/86 (m) free water level is reached, If the water level over the past thirteen years to1272/00 (m) about 6/20 mm reduced. In the present study, we believe that the gradual construction of 72 damscatchment basins with the average rate 4/5 billion cubic meters, the lake provides a huge change. Other factors,such as dam construction, the double-pass martyr station in front of the natural cycle of water under stirring thenatural order of living plant material suspended in the water cycle, the water creates many changes in theecosystem. The indiscriminate digging of the wells during the past seventeen years (91-74) of approximately 650thousand to 336 thousand Ring has increased among the factors that makes it believe that responsible decisionsin the coming years factors inland lake with a rejectUndoubtedly, completely separate the lake into northern andsouthern even completely dry lake will follow.
