Модель: Chalk deposition characterised most of the Late Cretaceous period in many areas of the world. In Tunisia it occurred predominantly during the Campanian - Maastrichtian stages. The facies, characteristic of the Abiod Chalk Formation, was sampled in four wells from the Miskar Gas Field (SE Tunisia), and at Le Kef section (NW Tunisia). A geochemical investigation of 19 elements in the Miskar wells and 12 elements at Le Kef has permitted to constrain vertical geochemical profiles suited for correlation. Eight chemostratigraphic units are defined in the offshore wells. Nine geochemical sequences (GCS) and eight isotope sequences (IsS) were correlated between Le Kef and Miskar. The 13C/12C curve for the Abiod Formation at Le Kef is correlated to other Tethyan, Boreal and NW Pacific Ocean sections. Fourteen correlation sequences (CC) are identified, two of which are considered to be major isotopic events: The correlation confirms that carbon isotope trends reflect global rather than local processes. Correlations can be used to test the validity of Campanian global biostratigraphic frameworks, and improve our understanding of the nature and timing of Late Cretaceous sea-level change. - посмотрите amina mabrouk chemostratigraphy of upper cretaceous chalk tunisia на сайте интернет-магазина.
Модель: sedimentology of the Late Cretaceous outcrops of Dokan limestone, Gulneri Shale, Kometan and Shiranish Formations in the areas that is located between Sulaimanyia and Arbil Governorate at northeastern Iraq. This area includes Dokan, Qamchuqa Gorge and Safeen Mountain. The lithology, stratigraphy and lithofacies of the above formations are studied in addition to inspection of their boundary conditions in the surrounding areas.The study area, as proposed, includes Dokan area, Qamchuqa Gorge and Safeen Mountain where the Late Cretaceous Dokan limestone, Gulneri shale, Kometan, and Shiranish Formations are cropped out. These Formations, according to Buday (1980), are deposited during two cycles, first is the Cenomanian – Early Campanian Cycle, the second is Late Campanian–Maastrichrian Cycle. The studied area constitutes a part of Zagros mountain belt, where the high mountain chains are in northwest southeast direction. The area is occupied by many mountains such as Sara, Kosrat, Gally and Safeen. - посмотрите amina mabrouk chemostratigraphy of upper cretaceous chalk tunisia на сайте интернет-магазина.

Модель: The palynological, palynofacies and organic geochemical analyses of 71 subsurface cuttings and 3 core samples from the GPTSW-7 well, Western Desert, Egypt, allowed the recognition of 5 biozones and 3 subzones. The combined optical (Spore colouration, palynofacies and vitrinite reflectance (Ro) and chemical (TOC and Rock-Eval pyrolysis) studies showed that, the Abu Roash and Bahariya formations, are primarily of kerogen III type, and hence gas-prone. The Abu Roash "F" Member contains a high proportion of AOM, high TOC and low OI values, indicating a highly oil-prone facies. This may be attributed to the presence of an organic-rich black shale layer, considered to be the sedimentary expression of a short-term global Oceanic Anoxic Event (OAE2). The palynofloral and palynofacies analyses show that, the Abu Roash “A” and “C” members, represent an oxic proximal and distal shelf environment, the Abu Roash “D” and “E” members, represent an oxic proximal shelf, while the Abu Roash “F” Member, was deposited in a distal suboxic-anoxic basin, the Abu Roash “G” Member and the Bahariya Formation, were deposited in a shallow marine and shallow marine to fluvio-deltaic environment, respectively. - посмотрите amina mabrouk chemostratigraphy of upper cretaceous chalk tunisia на сайте интернет-магазина.
Модель: As special results in extensional setting, the mafic dykes comprise lamprophyres, dolerites and diabase porphyrites. It is generally accepted that Mesozoic destruction accurred in the North China Craton, large-scale investigation on this have been done at the same time, however, controversies on the age, space, meachnism and contral factors appear due to minor investigation on the mantle-derived rocks. As one important Fault in the North China Craton, Mesozoic mafic dykes are widespread in the Tancheng-Lujiang Fault, indubitably, the special studies on these dykes can provide important evidence for the destruction of the NCC. This study using geochronological, geochemical, and whole-rock Sr-Nd-Pb isotopic data of the Mesozoic mafic dykes from the Tancheng-Lujiang Fault. Based on the systematic study, the main results are as follows: the mafic dykes were derived from the partial melting of an enriched mantle source due to the hybridization of subducted sedimentary rocks from Yangtze Craton during 122–125 Ma. In addition, the parental magmas of these dykes then fractionated olivine and Fe–Ti oxides during ascent and underwent negligible crustal contamination during magma emplacement. - посмотрите amina mabrouk chemostratigraphy of upper cretaceous chalk tunisia на сайте интернет-магазина.

Модель: This thesis is a foray into Romantic Italian melodrama through two of the soprano roles that defined them. Through Lucia (of Donizetti's "Lucia di Lammermoor") and Amina (of Bellini's "La Sonnambula"), the challenging and impressive soprano roles allowed for the woman's voice to be heard, and for the diva to emerge as we know her today. This thesis takes the reader through the history, culture, and music of early 19th century Italy, particularly through the "mad aria" in two key operas of the time. By learning about the music of madness, the reader can better understand Romantic Italian melodrama and the important path created for the birth of the diva. - посмотрите amina mabrouk chemostratigraphy of upper cretaceous chalk tunisia на сайте интернет-магазина.

Модель: This book presents one of the first 3D sequence-stratigraphy interpretations of the Cretaceous sequence in the Porcupine basin, offshore Ireland. This interpretation is based on a seismic dataset acquired from the NW margin of the Porcupine basin. This work includes a literature review, attribute extraction, and a basinward analysis of a set of high amplitude anomalies, along with a complete description of the methodology used for this research. In addition to improving understanding of the evolution of the basin during the Cretaceous, this work also correlates high amplitude anomalies with the interpreted stratigraphic framework, both in the structural domain and the time domain (Wheeler diagram). The book offers an enhanced insight into the deposition of sediment in the basin, and it presents new perspectives about the geological and stratigraphic interpretation of the basin’s history. - посмотрите amina mabrouk chemostratigraphy of upper cretaceous chalk tunisia на сайте интернет-магазина.
