Evidence of fractures from the image of the subsurface in the Akonolinga-Ayos area (Cameroon) by combining the Classical and the Bostick approaches in the interpretation of audio-magnetotelluric data

October 2009

  Exploitation of audio-magnetotelluric data has been realised by combining the classical and Bostick approaches with the objective to determine the structuring of layers in the Akonolinga-Ayos subsurface area. The work has been devoted to the processing and interpretation of audio-magnetolluric data of two profiles respectively Akonolinga-Mengueme and Mbang-Metol which are approximately running N-S and...

Characterization of high magnesian rocks for suitability as flux in iron and steel industry

September 2009

  Chromite resources of Orissa are mostly confined to Sukinda ultramafic belt and Boula Nausahi igneous complex. In these deposits, chromite is mainly present as layers in ultramafic rocks (high magnesian). These high magnesian ultramafic chromite overburden rocks are dumped as waste materials during chromite mining operations. These rocks are classified as dunite, peridotite and their altered products...

FE modeling along the SAF zone: Implication for the strong/weak SAF

August 2009

  FE modeling under plane stress condition was used to analyze the state of stress and failure in and around the San Andreas Fault (SAF) System. This study mainly focused on the state of stress at the general seismogenic depth of 12 km, imposing elastic rheology. The purpose of the present study was to simulate the regional stress field, displacement vectors and failures. Series of calculations were performed...

An analytical pre-feasibility study to generate rotary-percussive concept in hard rock TBMs

August 2009

  In this paper, an analytical modeling has been carried out to realize the effect of appending a supplementary percussive load to the rotary energy of tunnel boring machine's disc cutters, as a novel technology. In this path, two models have been built by using the theory of plasticity for prediction of the amount of penetration of a disc cutter assumed in form of a V-shaped indenter in rock medium. Since...

Groundwater recovery simulation for determination of post-mining lake formation at the Sangan iron mine, Mashhad, Iran

July 2009

  A two-dimensional axisymetric finite element software SEEP/W was used to simulate the groundwater recovery process in wells entirely confined in an aquifer at Sangan iron mine in Iran. The simulation model predicted very well with the results obtained from both analytical method and field data for well recovery process. It was inferred from the results that the rate of groundwater recovery process is...

Mineralogical, geochemical and geotechnical evaluation of Al-Sowera soil for building bricks industry in Iraq

July 2009

  The raw material soil of Al-Swera factory quarry (quarry soil and mixture) which is used for building brick industry were tested mineralogically, geochemically and geotechnically. Mineral components of soil characterizes by Clay minerals (Palygoriskite and chlorite), and non-clay minerals such calcite, quratz, feldspar, gypsum and halite. The raw material is deficient with SiO2, Al2O3, K2O, Fe2O3and MgO;...

Chemical composition, geophysical mapping and reserve estimation of clay deposit from parts of southwestern Nigeria

May 2009

  The present study is necessitated as a result of the use of kaolinitic clay as raw material for cement by West African Portland Company (now called Lafarge-WAPCO) situated in southwestern Nigeria. The study area covered an extent of 6 acres and fall within Ajebo town near Abeokuta. XRF and XRD techniques were employed in the determination of the chemical composition and crystalline component...

Occurrence of low grade concentration of niobium and tantalum in the granites of Eastern Uis region of Namibia: An exploration based study

May 2009

  The Uis region of Namibia is noted for its rare metal pegmatites that contain tin and the associated elements. However, during the Reconnaissance Geological study carried out by the author earlier, a granite area had shown high value of Ta2O5 and Nb2O5. This granite area was therefore subjected to a detailed exploration studies for tantalum-niobium mineralization. Localized enrichment of Ta2O5 and...
