Research ArticleOpen accessPhrase in the titleDOWNHOLE SEISMIC REFRACTION SURVEY OF WEATHERED LAYER CHARACTERISTICS IN ESCRAVOS, NIGERIAOchuko AnomohanranThe problem of datum correction in seismic surveys and the failures associated with civil engineering structures with specific reference to roads and buildings has been attributed to lack of understanding of the soil structure among others. This is why this survey on downhole seismic refraction was conducted from nine borehole locations in Escravos, Nigeria to determine the weathered layer characteristics … …American Journal of Applied Sciences, Vol. 11, Issue 3 · 30 Dec 2013 · 7,738 accessesView PDFCite
Research ArticleOpen accessIn the abstractImportance of Soil and Mineral Characteristics in Supporting Sustainable AgricultureIda Suryani, Marliana Sjuaib Palad, Nur Fitriani et al.Soil consists of four main components: Minerals, organic matter, air, and water, which are arranged in the space to form the soil body. Inorganic minerals in the soil come from rock fragments and other primary minerals. Sustainable soil fertility is supported by the nutrient content contained in the minerals. The research objectives were: 1) to observe the physical and chemical … …OnLine Journal of Biological Sciences, Vol. 25, Issue 2 · 25 Mar 2025 · 5,938 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Weathering Layer Characteristics over OPL-135 in the Western Part of the Niger Delta Basin, South-South, NigeriaOkechukwu Frank Adizua, Adekunle Oyemade Sofolabo, Olomu Ivory Obi-EgbediAn up-hole seismic refraction survey was carried out in OPL-135 in the Western part of the Niger Delta Basin, (SS) Nigeria. A total of thirty seven (37) up-hole locations in a (4.0×3.750) km grid configuration were drilled and logged over the prospect. The focal objective for the study was to assess the weathering layer characteristics over the prospect, specifically, to … …Current Research in Geoscience, Vol. 11, Issue 1 · 3 Feb 2021 · 11,449 accessesView PDFCite
Research ArticleOpen accessIn the abstractSoil Formation by Ecological Factors: Critical ReviewSaeed Zeraat Kar, Aydin BerenjianRegolith is the term we give parent material that has been weathered. The regolith consists of weathered bedrock near the surface including the soil layer. In the Iranian soil layer we will find: decayed parent materials, decaying plant material, decaying animal matter (manure) along with vegetation. Results of the present study show us that methods stimulating natural fertility in Iran … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 2 · 2 Apr 2013 · 7,663 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeoelectrical Resistivity Imaging and Refraction Seismic Investigations at Sg.Udang, MelakaZeinab Asry, Abdul Rahim Samsudin, Wan Zuhairi Yaacob, Jasni YaakubProblem statement: A Reconnaissance geophysical survey of an area near Sg.Udang, Melaka was conducted using geoelectrical resistivity and seismic refraction methods. The main objective of this study is to determine the depth of bedrock in the study area. The resistivity imaging measurement employing Wenner electrode configuration was carried out using an ABEM SAS 1000 terrameter and electrode selector system ES464. … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 1 · 13 Jun 2012 · 8,702 accessesView PDFCite
