Title: Characterization of Pegmatites in Ogodo-Odobola Area of Idah Sheet 267NW, Central Nigeria Authors: Alabi, Omanayin, Y. A., Waziri, N. M., Onoduku, U. S. A. A. Abstract: The pegmatites of Ogodo-Odobola area around Ajaokuta, Central Nigeria belong to the pegmatite belt of Central Nigeria. A detailed geological mapping of the pegmatites and host rocks was conducted with the aim of understanding their mode of occurrence and field relationship and to assess their mineralization potentials. Twelve (12) representative samples of rocks were selected for petrographic analysis. The results show that the area is underlain by migmatite-gneiss, schist, with intrusions of granite and pegmatite. The pegmatites occur in tabular form with varying widths (2 centimetres – 6 metres) and lengths (12 – 200 metres). Principal joint direction is NNE-SSW which is believed to have influenced the pegmatite emplacement. Petrography of the representative rock samples revealed an average mineralogical composition of biotite (23.90%), microcline (22.15%), hornblende (15.05%), quartz (10.65%), plagioclase (10.35%), muscovite (8.00%), myrmekite (0.20%), and opaque and accessory minerals (9.70%). The pegmatites were found to be dominated by microcline and plagioclase feldspars, and then muscovite, biotite, and accessory and opaque minerals. The pegmatite of the Ogodo-Odobola area is worth probing as the results have shown prospect for possible economic minerals. Description: xxxx

Title: Field Mapping and Mineralogical studies of rocks in part of Zungeru sheet 163 SE using Thin Section Petrography and X-ray Difraction Method Authors: Musa, T. Suleiman; Isah, A. Goro; Nuhu, M. Waziri; Abdulfatai, I Asema; Omanayin, Y Adenoyi; Muhammed, Nurudeen Omeiza Abstract: Mineralogical studies of rocks were carried out in parts of Gidan Kwano with an aim of investigating the mineralogical composition of the rocks using thin section petrography and X-ray Diffraction methods. The study area lies between latitudes 9 30 10N - 9 31 50N and longitude 6 26 10E and 6 27 30E covering aerial extent of 3.24km2 . Geological mapping of the area was first carried out to revealed the rock types which was then follow by the preparation of the section of carefully selected representative of the samples of the rocks in the area. X-ray diffraction was then carried out on the same selected sample to reveal the geochemical content of the rocks. The geological mapping revealed that the area is underlain by granite of medium to coarse grain rocks, with colour varying from leaucocratic to melanocratic. The minerals that could be identified in the hand specimen are mica, quartz and feldspar. Also structure such as joints, faults, quartz veins, and pegmatite veins were observed in the hand specimen with high modal percentage of quartz and orthoclase. The result from the XRD revealed the presence of of the following minerals in varying proportions muscovite, quartz, orthoclase, plagioclase, amblygonite and albite. Amblygonite is one of the few major lithium ores and could be used in producing aluminum products, batteries, ceramics, glazes and glass. Further geological, geophysical and geochemical propection is recommended to be carried out in the study area to determine the economic prospect of this minerals

Title: Gully Erosion in Rafingora, North Central Nigeria: Role of Geology and soil properties Authors: Muhammed, Nurudeen Omeiza; Abdullahi, Idris-Nda Abstract: Geological and geotechnical study of gully erosion was carried out in Rafingora, northern part of Bida basin to determine the lithologies of the area and assess the influence of geotechnical properties of the soil on the gully erosion. Field study across the gully profiles revealed 3 lithologies of highly erodible massive reddish sandstone underlain by light brownish clastic supported sandstone with cross bedding and herring-bone as structural imprint, underlain by light greyish mudstone of high resistance to gully influence. Results of the sieve analysis indicated that the soils in the area are poorly graded with average coefficient of uniformity Cu of 4.61 and coefficient of curvature Cc ranged between 0.4 – 2.54 indicating that the soils are poorly graded and susceptible to erosion. The soil in the area possess an average low Plastic index (19.52 ), Optimum Moisture Content (8.3), Maximum Dry Density (1.98), low values (22° and 18.9max) of AIF and cohesion and as well moderate glad2deen@gmail.com Coefficient of permeability (K) between 1.29 × 10-6 to 1.29 × 10-3 cm/sec. These indicate that such soil can only offer little resistance to the effect of both surface water and subsurface flow which made these soil to be loose, non-coherent and to slide upon getting in contact with water or even to disintegrate under dry conditions.

Title: Enhancing Nigeria Biogeochemical Capacity to Remediate Climate Change and Attain Food Security Authors: Muhammed, Nurudeen Omeiza Abstract: Nigeria faces significant challenges in achieving food security and mitigating the adverse effects of climate change. With a rapidly growing population, increasing food demand places immense pressure on the nation’s agricultural systems, which are often constrained by poor soil fertility, erratic weather patterns, and unsustainable farming practices. To address these issues, enhancing biogeochemical processes which govern the cycling of essential nutrients and greenhouse gases within the rock-soil-plant-atmosphere system has gained global recognition as a solution to the twin problems of climate change and food security. The concept involves the geoengineering of silicate rocks to facilitate Carbon Dioxide Removal (CDR) directly from the atmosphere while simultaneously enriching soil nutrients. Several studies conducted globally have highlighted the potential of silicate rocks such as basalt, glauconite, olivine, wollastonite, and serpentinite. These rocks are naturally abundant in Nigeria. For instance, basalt is found in the volcanic terrains of the Jos and Biu Plateaus; glauconite, also known as green sand, is located in the upper part of the Gongola Formation in Borno and the Agwu Formation in the Southern Benue Trough; olivine-rich rocks are found in the Zangon-Kataf area of Kaduna and the Jos Plateau; wollastonite is found in Kogi and Ogun States; and Serpentinite is found in Kaduna, Kogi, and Ogun States. Findings from these previous works indicate that geoengineering silicate rock weathering can sequester 1-4 tons of CO₂ per hectare annually, depending on the rock type and environmental conditions. Additionally, this process has the potential to enhance soil nutrients by releasing calcium, magnesium, potassium, and silicon, which improve crop yields and soil health. This underscores the need for research into the potential of these rocks to enhance Nigeria’s carbon footprint within the global community while simultaneously improving food security.
