The Maastrichtian-Palaeogene series of the Western High Atlas and Meseta Basins in Morocco are particularly rich in palygorskite. The present work is aimed at clarifying the genesis of palygorskite from the interbedded facies and gaining an understanding of their relationships with the depositional environment. The mineralogical characteristics of palygorskite from these series were studied by X-ray diffraction (XRD) and electron microscopy (SEM/TEM). The palygorskite content and microstructure show large geographical and stratigraphical variations in the deposits studied. The palygorskite occurrence is directly related to palaeobathymetry, since it is the dominant clay mineral in shallow marine and restricted environments. According to the morphology of palygorskite crystallites, four types of textures were distinguished. These types of palygorskite are polygenetic, formed by chemical precipitation, by the recrystallization of smectite clays or reworked by wind or water from sub-aerial environments. The difference between the two studied sub-basins with respect to palygorskite occurrence is attributed to the palaeomorphology of the hinterlands, to the tectonic differentiation and to the physical-chemical conditions of sea water.

Three chondrichthyan radiations are registered in the Famennian of the ArdenneMassif (Belgium). These radiations are already observed in Morocco and in the Carnic Alps, their acme being related with the early expansa transgression. Comparisons of univariate statistical descriptors like Margalef richness and Shannon–Wiener diversity index show variations between both margins of the Paleotethys, variations interpreted in terms of trophic relationships. The Ardenne area, a northern shallow carbonate platform is characterized during the Famennian by endemic shark taxa with durophagous dentition. The southern open deep-sea area, the Variscan Sea, contains large placoderms probably disclosing a negative feedback on “cladodont” chondrichthyans. This supports the hypothesis that the Armorica platelet behaved like a barrier between the central southern Laurussia and northern Gondwana. [less ▲]

A list of Devonian vertebrates from the Luga District of the Leningrad Region (Russia) was originally mentioned by P. N. Venyukov (1884). However, detailed palaeoichthyological studies in this territory started in only during 1926-1931 in the framework of the geological mapping programme. Two field crews studied the sections of the Middle and Upper Devonian by the Luga, Lemovzha, Oredezh, Tesovaya and Vruda rivers. One of the teams was the Devonian Lithological expedition under guided by R. F. Hecher. D. V. Obruchev was also involved in the works of this expedition. Other team headed by B. P. Asatkin surveyed the western part of the Leningrad Region. Both teams sampled numerous outcrops and boreholes, and collected abundant vertebrate remains. As a result the Devonian deposits were subdivided into the regional beds characterized by diverse vertebrate assemblages. Collectioning and research of Devonian vertebrates in this area continued in the 1950-1960ties by D. V. Obruchev and his students: V. N. Karatajute-Talimaa, E. Mark-Kurik, L. A. Lyarskaya. Their descriptions of Eifelian-Frasnian agnathans and fishes were published in the series of monographs or papers (e.g. Karatajute-Talimaa, 1963, Obruchev & Mark-Kurik, 1965, Lyarskaya, 1981). During the last thirty years J. Valiukevicius and some of the authors of the present report supplemented the vertebrate collections from some sections. The new localities in this area were reported by the 2001 Latvian-Russian Expedition (A. Ivanov, E. Luksevics, I. Zupins and others). The 2009-2010 Russo-Franco-Latvian expedition discovered a new diverse material from the historical and new localities of that area. [less ▲]

Palynological samples from two boreholes drilled in the eastern part of Saudi Arabia contain a rich assemblage of cryptospores and trilete spores. They are dated as most probably Lochkovian in age. Intriguingly, the cryptospores are very similar to those from a coeval continental palynomorph assemblage from the Old Red Sandstone Continent, whereas the trilete spores show a strong affinity with miospore assemblages from Western Gondwana. It is suggested that cryptospore-producing plants inhabited confined, damp biotopes and had a wide range of climatic tolerance. On the otherhand, trilete spore-producing plants inhabited a wider variety of biotopes but were more sensitive to climatic variations. The high degree of similarity between Old Red Sandstone and Saudi Arabian cryptospore assemblages favours palaeogeographic reconstructions where there is close proximity between Western Gondwana and Euramerica and/or a land connection between these palaeoplates. Climatic differences between the Old Red Sandstone Continent and the northern part of Western Gondwana can be invoked to explain the variations in the trilete spore assemblages.

GeoArabia Special Publication 1 <br /> <br />Knowledge of the Palaeozoic biostratigraphy of the Arabian Peninsula, situated close to the northern margin of Gondwana, was poorly known until a joint special project was held by the Saudi Arabian Oil Company (Saudi Aramco) and the Commission Internationale de Microflore du Paléozoïque (CIMP) in 1990. Prior to that only a small number of investigations had been published. Few efforts had been made to exploit the strati-graphic potentials of the many undescribed indigenous microfossils. The joint Saudi Aramco-CIMP project was designed to reverse that situation. Comprehensive studies were carried out on a range of microfossil groups throughout the Palaeozoic and results were published in 1995. <br /> <br />The 13 papers presented in this GeoArabia Special Publication update those initial findings. They clearly indicate the potential for these palynomorph assemblages to not only to provide a method for well-to-well correlations within Saudi Arabia, but also for establishing the palaeo-biogeographical relationships of the Arabian Plate relative to adjacent landmasses. The conclusions that are proposed here can now be compared with datasets throughout North Africa and with the central and southern parts of South America. <br /> <br />Editors: Sa’id Al-Hajri and Bernard Owens <br />231 pages <br />40 plates/62 illustrations [less ▲]

Istanbul and its 12 million inhabitants borders the Marmara Sea, a submarine pull-apart basin related to the North Anatolian Fault (NAF), a major strike slip fault that ruptures in M>7 earthquakes. Constraining the recurrence rate of M>7 earthquakes that threaten the megacity is problematic because the active faults are submarine. For assessing past submarine earthquake ruptures of the Cinarcik Fault Segment located just south of Istanbul, we studied two sedimentary cores and identified seismoturbidites related to historical ruptures. Earthquake related turbidites are identified in both cores, based on their distinctive sedimentological and geochemical signatures. The seismoturbidites recorded in one of the core named Klg04 are inferred to record only mass wasting events related to the rupture on the Cinarcik Segment because of its specific geomorphological location. To constrain the seismoturbidites chronology, we combine short-lived radionuclide, radiocarbon and paleoinclination data. The first four seismoturbidites recorded match the 1894, 1509, 14th century and 989 historical earthquakes. The obtained age model allows us to discuss past historical rupture scenario across the Marmara Sea. The fact that the 1766 earthquakes are not recorded is further discussed based on new macroseismic intensity data and sedimentary records East of the Cinarcik Basin. [less ▲]
