Meteorite Fall

The Tissint fireball is the only fireball to have been observed and reported by numerous witnesses across the south-east of Morocco. The event was extremely valuable to the scientific community; show an extraordinary and rare event and were also the brightest and most comprehensively observed fireball in Morocco’s known astronomical history. Since the abstract of A. Ibhi (2011) [1]. In 2012-2013 concerning a number of Martian meteorite fragments found in the region of Tata (Morocco), a number of expeditions have been made to the area. A. ibhi has done a great amount of field work. He discovered the strewn field and collected the fragments of this Martian meteorite and many information. Each expedition has had the effect of expanding the size of the strewn field which is now documented to cover more than 70 sq. kilometers. The size of the strewn field is now estimated to be about a 17 km long.

The aim of the article is the identification and characterization of complex factors acting simultaneously on forming a large-sized reservoirs in the deep South Caspian Basin, as well as the formation of a model based on a combination of causing the formation of hydrocarbon deposits synchronously occurring natural processes. The article comments on reasons for high layer pressures existing in the fields located in the South Caspian Depression (SCD), studies impacting factors and develops a methodical estimation on this basis. The tectonic factor and density-barometric model can become the main criterion for selection of priority projects for exploration, site selection for drilling and to accommodate exploration and production wells. Obtained results allow conducting effective studies of the exploration and development of oil and gas condensate fields in the SCD area.

Abstract The southern part of the South Caspian oil and gas Basin (SCB) is one of the main oil and gas producing regions in the central part of Eurasian continent. The large number of offshore oil and gas fields is located here, therefore the basin considered as a promising direction for the further perspective zones survey. The basin is located between the uneven-aged mountain structures of the Lesser and Greater Caucasus in the west, the Great Balkhan and Kopet-Dag in the east, the Talish and Elbrus ridges in the south. In the north, it is limited by a sub-latitudinal regional deep fault, which fixes the northern slope of the complex Absheron-Balkhan zone of uplifts, which is part of the South Kura and Western Turkmenistan depressions. Among the structural elements of the second order, the South Absheron depression, the complex Abikh swell and the Javadkhan-Natevan zone in the west should be noted; Turkmen terrace, Ogurchinskaya step and Chikishlyar-Fersmanovskaya-Weber-Western zone in the east (Fig. 1). The central place in the structure of the basin is occupied by the South Caspian Mega Depression (SCMD), in the most submerged part of which - the pre Elbrus Basin - the basement lies at a depth of about 25 km, and the sedimentary stratum, including Mesozoic, Cenozoic and Quaternary formations, is largely represented by the Pliocene - post-Pliocene sediments, reaching a total thickness of 8–10 km and more in the troughs (Fig. 2, 3).

The article explores the oil and gas generation properties and hydrocarbon content of Lower Kur depression and Baku archipelago based on the studies of morphology, space position of local uplifts, types of faults, evolution of mud volcanoes, distribution properties of compressive stresses and earth temperature environment. It was defined that as a result of action of longitudinal and lateral folding mechanisms predominantly brachy-form structures had been formed, the anticline zones and trends of which show that their space position is controlled by compressive stresses arising within the narrow north-western part of the Iranian-Afghani plate. The folding process in Oligocene-Pliocene series of the South-Caspian depression basically takes place due to the dynamics of active Maikop clays. Local uplifts of reviewed area are originated no later than the end of the Miocene. Carried out analysis justifies that the intensity of folding processes within Lower Kur depression and Baku archipelago rises both in time and from the south-east towards the north-west. A diagram of vertical oil generation zoning for Lower Kur depression and Baku archipelago has been developed based on the earth temperature data, according to which it was established that the Upper Cretaceous, Paleogene-Miocene sediments and the Productive Series represent strata generating commercial oil and gas.

Granitic Layer

A profile of deep seismic sounding across the South Caspian depression is described. The peculiarity of the structure of the depression is the reduced thickness of the Paleozoic and Mesozoic folded complexes, which is indicative of its geanticlinal development at that time. These complexes have seismic velocities in the range usual for granites. They were not discovered in earlier seismic studies in the Black Sea and Caspian Sea because the complexes are too thin, and the methods used did not allow discovery of detail. One peculiarity of these depressions is the so-called 'sedimentary-basaltic' crust. This arises when strongly metamorphosed rocks have been overlain by thick, poorly consolidated sediment, after a long period of submergence.
