The main focus was logging a 25 km-long transect along Oued Draa, which records the Early Cretaceous continental to marine transition, and runs parallel to the existing transect logged along Oued Chebeika about 50 km to the SW. The aim is to establish an outcrop-based correlation and suite of facies models for the Early Cretaceous succession. Resampling was undertaken to improve the biostratigraphic dating through macro- and microfossils and palynology. Current work includes microfacies characterization of the re- dated Jurassic mixed siliciclastic-carbonate marine succession in the Ifni area, working in collaboration with Mike Simmons and Luc Bulot, in order to more precisely date this section and document the rift and post-rift evolution of this part of the Tarfaya Basin.

ABSTRACT:- Stable isotopes and geochemical studies have been applied in the investigation of groundwater resources in Sokoto Basin, northwestern Nigeria. Generally, the characteristic hydrochemical classification in the study area is calcium-alkali-bicarbonate. Surface waters are characterized by alkali-calcium-bicarbonate while groundwater is of Ca-Mg-HCO3. The plot of δ18O versus δ2H shows that five isotopic groups can be distinguished. Group I-III is of groundwater origin while group IV and V represent surface water. A combination of the hydrochemical and isotope data (14C, 13C and 3H) reveals the Sokoto basin aquifers generally contains good quality groundwater of Holocene age (100 to 10,000 years BP).

  • Oblique Rifting of the Equatorial Atlantic: Why There Is No Saharan Atlantic Ocean
    Originally published as: Heine, C., Brune, S. (2014 online): Oblique rifting of the Equatorial Atlantic: Why there is no Saharan Atlantic Ocean. – Geology 10.1130/G35082.1. Oblique rifting of the Equatorial Atlantic: Why there is no Saharan Atlantic Ocean 1 2,1 Christian Heine , Sascha Brune 1 EarthByte Group, School of Geosciences, The University of Sydney, NSW 2006, Australia 2 Helmholtz Centre Potsdam, GFZ German Research Centre for Geosciences, Section 2.5, Geodynamic Modelling, Potsdam, Germany ABSTRACT Rifting between large continental plates results in either continental breakup and the formation of conjugate passive margins or rift abandonment and a set of aborted rift basins. The driving mechanisms behind “successful” or “failed” rifting have so far never been scrutinized by joint kinematic and forward numerical modelling. We analyse the Early Cretaceous extension between Africa and South America which was preceded by about 20-30 Myrs of extensive rifting prior to the final separation between the two plates. While the South and Atlantic conjugate margins continued into seafloor spreading mode, forming the Atlantic ocean basin, Cretaceous-aged African intraplate rifts eventually “failed” soon after South America broke up from Africa. We address the spatio-temporal dynamics of rifting in domains by comparing a new plate kinematic model for the South Atlantic and 3D forward rift models. This joint approach elucidates (1) the dynamic competition of Atlantic and extensional systems, (2) two stage kinematics of the South Atlantic rift system, and (3) the acceleration of the South American plate prior to final break-up. We suggest that obliquity the success of the Equatorial Atlantic rift, ultimately prohibiting the formation of a “Saharan Atlantic Ocean” in the Early Cretaceous, and exerting a primary control on the increase in observed extensional velocities between the South American and African plates.

  • The Sokoto Basin (Nigerian Sector of the Iullemmeden Basin)
    Chapter 6 The Sokoto Basin (Nigerian Sector of the Iullemmeden Basin) The Iullemmeden Basin in north-western Nigeria is known locally as the “Sokoto Basin”. It consists predominantly of a gently undulating plain with an average ele- vation varying from 250 to 400 m above sea-level. This plain is occasionally inter- rupted by low mesas. A low escarpment, known as the “Dange Scarp” is the most prominent feature in the basin and it is closely related to the geology. The sediments of the Iullemmeden Basin were accumulated during four main phases of deposition. Overlying the Pre-Cambrian Basement unconformably, the Illo and Gundumi Formations, made up of grits and clays, constitute the Pre- Maastrichtian “Continental Intercalaire” of West Africa. They are overlain uncon- formably by the Maastrichtian Rima Group, consisting of mudstones and friable sandstones (Taloka and Wurno Formations), separated by the fossiliferous, shelly Dukamaje Formation. The Dange and Gamba Formations (mainly shales) separated by the calcareous Kalambaina Formation constitute the Paleocene Sokoto Group. The overlying continental Gwandu Formation forms the Post-Paleocene Continental Terminal. These sediments dip gently and thicken gradually towards the northwest, with a maximum thickness of over 1,200 m near the frontier with Niger Repub- lic. The geological map of the Sokoto Basin of northwestern Nigeria is shown on Fig. 6.1 while Fig. 6.2 summarizes the geological sequence in the basin. Pre-Maastrichtian Deposits (The Continental Intercalaire) In the Sokoto Basin, the pre-Maastrichtian sediments are of fluviatile and lacustrine origin. They belong to the Illo and Gundumi Formations which extend northwards into Niger Republic.

  • Overview of Lullemmeden Basin for Co2 Sequestration Potential in North-Western Nigeria
    INTERNATIONAL JOURNAL OF SCIENTIFIC & TECHNOLOGY RESEARCH VOLUME 3, ISSUE 3, MARCH 2014 ISSN 2277-8616 Overview Of Lullemmeden Basin For Co2 Sequestration Potential In North-Western Nigeria I. Yusuf, N.G Obaje, B.Jibrin, M.T Tsepav, H.M Liman Abstract: Sedimentary basins are suitable to a different degree for CO2 geological sequestration as a result of various intrinsic and extrinsic characteristics. This paper screened and ranked the Iullemmeden Basin of Nigeria sector based on Bachu (2003) ranking and screening criteria; evaluating factors such as tectonic setting, basin size and depth, geology, hydrogeology, hydrocarbon potentials, climate, geothermal, existing resources k and industry maturity in respect to these criterion. The results shows to rank the Basin to have R score value of 0.41 against the fi, n = max (fi) value equal to 1 as highest value of the function characterize the best in terms of suitability for the criterion in which this ranking are based upon. The paper also reveals as findings of some intrinsic characteristics such as; poor intercalated geologic formation, shallow aquifer systems within sedimentary pile in the basin which make the basin not suitable CO2 sequestration and when other parameters in future are favoured; it would possess the risk of CO2 leakages and groundwater contaminations in the geological storage media. Regional screening and ranking of the adjoining basins are recommended, while detailed local site characterisation of the basin is needed to assess its overall suitability for CO2 sequestration

The basin fill succession consists of the Late Jurassic conti- nental facies and Cretaceous marine deposits topped by Mid-Paleogene continental facies. Impressive outcrops had spurred the search for petroleum in early colonial time but the poor showing of the earliest boreholes discouraged the efforts. This study is, therefore, aimed at providing more information on one of the prerequisite attributes- reservoir characteristics using outcrop- ping analogues for assessing the lithostratigraphic units that bear the potential reservoirs.
