Full textAmong the carved animal figures that appeared in North Africa during prehistory, the antique buffalo, omnipresent throughout the Saharan Atlas during the Neolithic, features prominently.Our study focused on 141 of these hartebeest engravings, spread over the various links constituting the Saharan Atlas of which 79 have been studied by us on the spot. This study consolidates and analyses data scattered in multiple works, to which are added our discoveries which have enriched the record and expanded the spatial distribution of these engravings. This wealth is not only quantitative, it is also qualitative. This important spring stylistic, thematic and technical highlights the regional schools and Saharan influences. Our research has allowed a better understanding of the stylistic and iconographic traditions of figuration of this animal and allowed us to situate them in their chrono-cultural and geographical context.The representations of the antique buffalo whose developed some forms, involved in defining cultural provinces, reveal the investment and the choice of artists in a varied bestiary that was represented differently depending on the region and atlasiques schools

Full textThe southern piedmont of the djebel amour (saharian atlas, algeria) is a physical, climatical and human fragile transitional environment, propitious to land degradation. Relatively preserved until now comparatively to the northern piedmont of the saharian atlas, the southern piedmont shows actually an exacerbation of the land degradation processes. We have made an inventory of shapes and formations of each morphological unit of the piedmont, and more, we have defined his evolution processes during the last dry period (started in 1970, ended in 1986), differentiating what is caused by human or by drought, with a multitemporal monitoring of dense and sparse vegetation and sandy shapes and formations using 3 different images (mss 1977, spot 1986 and tm 1989). The phenomenon of land degradation increases from 1977 to 1986 and disapears in 1989 thanks to the improvment of pluviometric conditions, indicating that we didn't reach an irreversible stage. The location of these degraded patches around towns, wells and springs shows that the human causes are preponderant in degradations development. The drought only reveals increasing anthropogenic degradations. This satellite monitoring has shown that land degradation processes progress in a discontinuous manner responding to land use. Human activities tend to aggravate natural evolution processes appearing through forms and formations inherited from more arid or humid periods

Full textThe analysis of serial sections series across the platform to basin transition in various palaeogeography contexts allowed to determine the sequential context of the Cenomanian-Turonian boundary judged often as transgressif. The sequential heterogeneousness seems to be the rule in the passage on a short interval time, during which show themselves phenomena of oceanic anoxia. The δ13C anomalous characteristic to the Cenomanian-Turonian boundary is interpreted as the result of a global phenomenon which is added a local signature (local tectonics, subsidance). This anomalous can be a tool of correlation with high resolution is within a pond or enters various pond studied. It seems delicate to use the biozons of planctic foraminifera in the absence of all other independent signal (as δ13C) to establish correlations which want in high resolution

Full textThe Saharan Atlas Mountains, South of Oran includes the ‘Ksour Ridge’, a mountainous region compr ising SW-NEranges. Cretaceous depressions are represented by flat-bottomed synclines overhung by anticlines, mainly Jurassic. Thesandstone formations, so-called Continental Intercalary, of the Ain Sefra region contain an unconfined significant waterresource for dr inking water and ir r igation. The hydrogeological study and identification of aquifers prove the impor tantinterconnection between the Continental Intercalary and the Jurassic aquifers. In a recharge area character ized by a semiaridor an arid climate, therefore a low annual rainfall, effective rainfall is the hardiest item to estimate, as it was demonstrated byclassical monthly hydrological balance computations. The methodology proposed in this work relies on spatial and temporalinterpolations of scarce climatic data. This methodology can be used to determine the recharge flow to aquifers of these zones.The Ain Sefra’s syncline includes the sandstone aquifers of Continental Intercalary and of the Plio-Quaternary layers. Threeyears, with contrasting annual rainfalls, are chosen in this application: 1983 as dry year , 2006 as average year , and 2008 ashumid one. This application requires information about the soil nature, thickness and porosity, the sur face and the altitude ofthe recharge areas. The rainfall and the recharge flow to aquifers indicate that the pr incipal recharge areas are the Jurassicoutcrops, mainly dur ing the humid years, when the annual rainfall exceeds 300 mm. The chemical character istics of waterhave been submitted to different statistical analyses. As a fi rst approach, a pr incipal component analysis (PCA) displayed threeclusters of water cor responding to the three aquifer layers which are exploited. Discr iminant factor analysis (DFA) was usedto character ize the impor tance and to rank the parameters responsible for this high mineralization (between 2000 and 4000mg/ l), namely: system character istics (lithology), structural geology (fault and Tr iassic diapirs). After estimating the effectiverecharge (ranging between 0 for a dry year, and 684 mm/ year for a humid one) and identifying groundwater flow, and inorder to predict the hydrodynamic behavior of Ain Sefra’s syncline, it is essential to implement a mathematical model. Wewere only able to establish the model of the Garet El Kheil hydrogeological unit, given the data unavailability on the other twounits (El Hanjir -Ain Sefra, Ain Sefra-Tiout). We chose a finite difference method in permanent mode to improve knowledge ofthe hydraulic character istics of aquifer , and to evaluate a complete hydrological balance, using the simple and convenient"ASMWIN" code. Exploitation of the model made it possible to determine the impact of the pumped yields, and the weathertrends on the piezometr ic evolution of the aquifer . Two operating scenar ios have been proposed: halving recharge (-50%: 810 6 m 3 / year instead of 16 10 6) and doubling the well’s yield (+100 %: 2.72 10 6 m 3 / year , instead of 1.36 10 6). Weconclude that the groundwater resource is more vulnerable to the climate change than intensive use of aquifers, meaning thatthe aqui fer is underexploited at present
