...Federico Ortí; Laura Rosell; Javier García-Veigas; Cahít Helvaci Abstract: Probertite and glauberite are the main rock-forming minerals in the lacustrine Doğanlar succession of the Emet basin. The present paper seeks to characterize and interpret the facies and depositional settings of this mineral...

... + quartz + minor smectite, and K-rich feldspar + quartz + smectite assemblages in horizontal zones extending from north to south in the Emet basin. Yalçin and Gündoğdu (1985) conducted the first detailed study on the clay mineralogy of these volcaniclastic sedimentary units. The unit underlying...

L’analyse de plus de 50 échantillons d’affleurements du Triassique inférieur et moyen montrent des degrés de maturité variables au sud de la rivière Pine (membres Whistler et Vega-Phroso), mais les...

... basin ( Lopatin and Emets, 1987 ). High heat flow at the rift stage of the basin evolution or during its thermal reactivation are the most probable causes of such changes. This scenario was demonstrated for the Viking Graben by Iliffe et al. (1991) . High thermal gradients commonly are associated...

.... Thermal maturity of Jurassic sediments in the West Siberian basin has been largely studied ( Ammosov et al., 1987 ; Bostrikov and Fomichev, 1991 ; Ermakov and Skorobogatov, 1990 ; Fomin, 1992 ; 1995 ; Kontorovich et al., 1967a , b ; 1975 ; Lopatin and Emets, 1984 ; Parparova et al., 1981...

...% vitrinite reflectance (R o ). In the northern part of the basin, TOC values range mostly from 1.5 to 3% but can reach 17% in some coaly layers ( Lopatin and Emets, 1987 , although they describe Togur-equivalent lower Toarcian deposits as the Djangodskiy horizon of the Tyumen Formation). According...

...Victoria C. Hover; Gail M. Ashley Abstract Olduvai Gorge, Tanzania (East African Rift) exposes a 100 m thick Plio-Pleistocene sequence of dominantly volcaniclastic sediments deposited in a 50 km wide closed basin containing a playa lake. A scanning transmission electron and analytical electron...

... Yanchang Formation that are dominated ( > 90 % by volume) by grains derived from outside the basin of deposition (terrigenous-argillaceous mudstones or tarls). Major extrabasinal grains are K-rich clay, quartz, plagioclase, K-feldspar, lithic fragments, and micas. In terms of the quartz-feldspar-lithic...

... potential in volcanic and metamorphic rocks. However, many hydrocarbon-bearing basins containing volcanic and metamorphic rocks have been found in convergent margin settings and in rift basins. This article describes the reservoir lithofacies and wire-line logs and elucidates the parameters controlling...

...Caineng Zou; Songqi Pan; Brian Horsfield; Zhi Yang; Siying Hao; Entao Liu; Leifu Zhang ABSTRACT The Zhang 22 well was drilled in the Ordos Basin, penetrating the Chang 7 Member of the Triassic Yanchang Formation, which, cumulatively, has more than 80 m (>260 ft) of black organic-rich shale...

... identification of organic matter according to the pristane/phytane ratio and the biofacies and sedimentological data is due to the low catagenetic maturity of OM. The Volgian was marked by a significant transgression of the Anabar–Lena sea, which was gradually changed by a successive regression of its basin...

... playa lakes, in which small Fe-rich deposits precipitated on the basin margins, while brines rich in boron and Mg accumulated and precipitated salts in the basin centers. The Fe-rich borate bodies tend to be larger and lack the spatial zonation of the Mg-rich deposits, suggesting that they were...

... deposits that have been pedogenically modified into paleosols (UM1p and UM7p, respectively). This study provides the first detailed mineralogical and geochemical analyses of the clays of this important Pleistocene basin. The smectitic clays, which show abundant evidence for pedogenesis, were apparently...

...Ş. Ali Sayin; Nurdan Yavuz; Serap Içöz Abstract The Çankırı Basin is one of the largest Cenozoic basins in Central Anatolia, Turkey and contains possible economic hydrocarbon and evaporite reserves. Gypsum is the dominant mineral in the evaporite-bearing Pliocene deposits of the Çankırı Basin...

...Muazzez Çelik Karakaya; Necati Karakaya; Fuat Yavuz Abstract The pyroclastic sediments studied here contained varied amounts of zeolite and were formed in the saline alkaline Tuzgölü Basin following the alteration of dacitic volcanic materials during the Early to Late Miocene.
