4.4 GEOLOGY The Study Area is located within the Niger-Delta Basin and Benin formation and along with <strong>Edo</strong> State is geologically characterized by deposits laid during the tertiary and cretaceous periods (Alile, Molindo and Nwachokor, 2007). The Benin Formation has been created from weathered sedimentary rock (Aziegbe, 2006). The Niger Delta Basin is one of the sedimentary basins in Nigeria that derives from weathered and eroded materials of Precambrian basement complex rocks of the South-Western part of Nigeria (NIPP, 2010). The Benin Formation comprises unconsolidated iron oxide-rich sands with alternating beds of shale, clay and sandy clay. The sands range from fine to medium and in places demonstrate coal lignite streaks and wood fragments. The formation is covered with loose brownish sand (quaternary drift) varying in thickness and is about 800 m thick; almost all of which is water bearing with water level varying from about 20 m to 52 m. It is generally believed to be highly permeable, porous and prolific in water yield. The aquifer yields range from 28.4 m 3 hr-1 at Iyanomo (south of the City), 125 m 3 hr-1at Uselu (central part) to 208 m 3 hr-1 at Ogba (northern part) with a draw down ranging from 4.8 m at Iyanomo, 1.8 m at Uselu to 6.7 m at OgbaDue to the estimated rainfall for Benin City of over 2000 mm per annum (Erah, Akujieze and Oteze, 2002) The upper layer of the Benin formation is composed of iron-rich red earth derived from iron-stained fragmented parent rock (NIPP, 2010) and derives from the Oligocene era. 4.5 SOILS Soil sampling was conducted at nine locations during the dry season in the Study Area (including areas to the south and west of the proposed plant location) and at nine locations during the wet season (Figure 4.3). The sampling locations with latitude and longitude coordinates for all biophysical variables measured are included in Annex B. All core soil samples were taken at two depth intervals (0 - 15cm of topsoil and 15 - 30cm of subsoil) using a stainless steel auger. The soil samples were then stored in plastic buckets, and homogenised before sub-sampling. The sub-soil samples were subsequently stored on ice (below 4 º C) and transported to Searchgate Laboratories. The soil samples were analysed according to their physico-chemical, heavy metals, oil and grease, hydrocarbons, and microbiological properties. Soils were also analysed on site for colour, texture and moisture content. Soil analysis results are outlined below, and full laboratory results are provided in (Annex B).
