RISDIAGENESIS OF NON-MARINE PETROLEUM RESERVOIRS: THE NEOCOMIAN (LOWER CRETACEOUS) SHURIJEH FORMATION, KOPET-DAGH BASIN, NE IRAN
Detailed petrologic, sedimentologic and geohistory analyses have been carried out on the
Neocomian (Lower Cretaceous) Shurijeh Formation in the eastern part of the Kopet-Dagh Basin, NE
Iran. The results of ...
Petrographical and geochemical evidences for paragenetic sequence interpretation of diagenesis in mixed siliciclastic–carbonate sediments: Mozduran Formation (Upper Jurassic), south of Agh-Darband, NE Iran
of d18O and d13C in carbonate rocks show two different trends. High depletion of d18O and low variation of d13C probably reflect increasing temperatures during
burial diagenesis, while the higher depletion in carbon isotope values with low...
Carbonate Diagenesis of the Upper Jurassic Successions in the West of Binalud - Eastern Alborz (NE Iran)
that these deposits have undergone both meteoric and burial diagenesis in a relatively open system with moderate water-rock interaction. The positive trend between trace elements and oxygen
isotope depletion also support these burial conditions. Lighter δl8O...
Discerning primary versus diagenetic signals in carbonate carbon and oxygen isotope records: An example from the Permian–Triassic boundary of Iran
. The results show that the use of paired C-O isotopes and Mn-Sr concentrations is not sufficient to identify diagenetic alteration in bulk materials, because δ13C-δ18O covariation can be due to environmental factors rather than diagenesis, and Sr/Ca and Mn...
Diagenetic features, stable isotope and dolomitization of the Lower Cretaceous carbonate rocks in west Kopet-Dagh Basin, Northeast Iran
The Lower Cretaceous carbonates succession -Shurijeh and Tirgan formations- in west Kopet-Dagh basin -NE-Iran- was examined to study the diagenetic modifications. Various diagenetic processes were controlled by the original ...
Geochemistry of Late Cretaceous phosphorites in Egypt: Implication for their genesis and diagenesis
Phosphorite deposits in Egypt, known as the Duwi Formation, are a part of the Middle East to North Africa phosphogenic province
of Late Cretaceous to Paleogene age. Phosphatic grains in these deposites are classified ...
Identification of pore types and pore facies for evaluating the diagenetic performance on reservoir quality: a case study from the Asmari Formation in Ramin Oil Field, SW Iran
The purpose of this study is to identify the pore types and distinguish the pore facies based on the diagenetic performance. The petrographic examination of 230 thin sections lead to the identification of a variety of ...
Diagenesis and geochemistry of siliciclastic facies from Ordovician of Rahdar Mountain, western Tabas
مطالعات دیاژنتیکی و ژئوشیمیایی رخساره‌های سیلیسی آواری منتسب به اردوویسین کوه راهدار، غرب طبس
در این تحقیق، مطالعات پتروگرافی، ژئوشیمی عناصر اصلی و کمیاب برای تعیین خاستگاه، جایگاه تکتونیکی و شرایط آب و هوایی قدیمه ناحیه منشأ ماسه سنگهای اردوویسین کوه راهدار انجام شده است. از نظر پتروگرافی این ماسه سنگها شامل ...
