...Ghania Kiared (Ould-Amara); Mostefa Bessedik; James B. Riding A continuous study of atmospheric pollen in Oran Province, northwest Algeria, using the Cour method was undertaken between April 2004 and April 2006. A pollen-collecting device was placed in the meteorological station at Es-Sénia airport...

... of its spatio-temporal trends provides useful information for effective planning and management of water resources. Daily rainfall data collected from 12 meteorological stations in the downstream Mekkera Basin, Northwest Algeria, between 1975 and 2011 were analyzed using the innovative polygon trend...

...A. K. Yelles-Chaouche; R. Ait Ouali; R. Bracene; M. E. M. Derder; H. Djellit Abstract The Ksour mountains (northwest Algeria) belong to the western part of the Saharan Atlas. They are located between the High Plateau to the north, the South Atlas Front to the south and the Moroccan High Atlas...

...H. W. Underhill Abstract Deals principally with results of hydrologic investigations in the Chergui closed basin in the high plains region of northwest Algeria. The ground water which occurs immediately below the surface is highly saline, but the presence of several freshwater springs suggested...

... biostratigraphic data for the Glib Zegdou fauna, suggests an age ranging between 49 and 45 Ma for this section. The high-resolution magnetostratigraphic study of the poorly known continental Eocene Epoch of Algeria provides new insights into the early Tertiary stratigraphy of northwest Africa. The placement...

...Bruce C. Heezen; Maurice Ewing ABSTRACT An earthquake of magnitude 6.7 violently shook the area near Orléansville, Algeria, on September 9, 1954. The area of appreciable damage extended 15 miles from the epicenter, and following the earthquake five submarine cables lying on the floor...

... of traveltime values means that we can construct an exactly linear inverse problem for reservoir flow properties. Application to interferometric synthetic-aperture radar (InSAR) data gathered over a carbon dioxide ( C O 2 ) injection site in Algeria reveals pressure propagation along two northwest-trending...

... field, Algeria, we image pressure propagation to the northwest. An inversion for flow properties indicates a linear trend of high permeability. The high permeability correlates with a northwest trending fault on the flank of the anticline that defines the field. © 2008 Society of Exploration...

... of carbon dioxide (CO 2 ) for both long-term storage and enhanced oil production. An application to the geologic sequestration of CO 2 in Algeria revealed northwest migration along a fault/fracture zone intersected by the injection well. A study in a Texas field demonstrated that enhanced oil recovery...

...K. Layadi; F. Semmane; A. K. Yelles‐Chaouche Abstract Weak‐motion recordings of local earthquakes and ambient vibration data in the 0.2–15 Hz frequency range were used to quantify site effects in downtown Chlef city, Algeria. Nine short‐period stations were installed in the city. A total of 15...

... the northwest margin of Paraná Basin. The Monstrocrinus occurrence is rare in the Middle Devonian, until now known in Germany, Spain, and Algeria Lower Devonian (upper Emsian) and only in northern Brazil in the Middle Devonian (Eifelian.) These facts provide valuable arguments for paleogeographic...

...JOËLLE CARPENA; JEAN-ROBERT KIENAST; KHADIDJA OUZEGANE; CÉLESTINE JEHANNO Abstract This fission-track study is performed on the apatites from the In Ouzzal (northwest Hoggar, Algeria) carbonatite complex and permits us to present a complete thermal history of this Archean core. Two types...
