Book Description
Contains details on the geological units of Nigeria and the associated mineral resources. The book is divided into three parts. Part 1 discusses the geology of the crystalline rocks and their regional distribution while the sedimentary basins constitute the subject of Part 2. Part 3 takes the mineral resources of Nigeria one on one, their geological environment, mode of occurrence, localities and where possible the reserves estimation. Thereafter, an account of the previous and current mining policies (including that of petroleum) of the Nigerian government is given and goes ahead to list some specific investment opportunities in the solid minerals sector.

Book Description
Research Paper (postgraduate) from the year 2007 in the subject Geography / Earth Science - Geology, Mineralogy, Soil Science, grade: A, Abubakar Tafawa Balewa University, course: Applied Geology - Economic Geology/ Mineral Exploration, language: English, abstract: Barite (BaSO4) mineralization occurs within Pan African fracture systems in the Gombe inlier. Gombe Inlier is a Basement dome within the Gongola Basin (Upper Benue trough in Nigeria) which exposes most of the stratigraphic sequence (Bima Sandstone, Yolde Formation, Pindiga Formation and Gombe Sandstone). Fieldwork was conducted from March 23rd – 29th 2007, 20 minerals and rock samples were taken from the veins and host rocks, and then Geochemical, petrographic and structural analysis were conducted to ascertain the quality of barite, associated minerals, nature of host rock and also the type of chemical as well as structural barriers for the mineralization. The results shows that the principal planar planes hosting mineralizations were found to trend mostly in NE – WSW direction which conforms well in smaller scale with the trend of strike slip faults that faulted the inlier and on a larger scale conforms with the general trend of the Benue trough. The fractures are therefore probably subordinate to the general structural trend of the Benue trough. The main associated mineralization was inferred to be anhydrite (CaSO4) which is also a sulphate like barite. This suggest competition for SO32+ by Ba2+ and Ca2+ but the deeper fractures host barite because Ba2+ originate from mantle and brought up by hydrothermal fluid through fractures while Ca2+ could be a dissolved ion in sea water. The quality of the barite in some veins is well over 70% BaSO4 which is economically viable. Part of barite in some veins were leached and recrystallized into spindle crystals by later hydrothermal fluid with little effect on its chemistry. The petrographic studies also revealed the purity of some barite veins and also indicated the presence of other associated minerals and also indicates the nature of the silica chemical barrier for the sulphate mineralizations.

Book Description
This edited book is based on the papers accepted for presentation during the 2nd Springer Conference of the Arabian Journal of Geosciences (CAJG-2), Tunisia, in 2019. Major subjects treated in the book include geomorphology, sedimentology, and geochemistry. The book presents an updated unique view in conjugating field studies and modeling to better quantify the process-product binomial unusual in geosciences. In the geomorphology section, 24 papers deal with topics related to fault slip and incision rates, soil science, landslides and debris flows, coastal processes, and geoarcheology, and geoheritage. Under the sedimentology section, 34 papers including stratigraphy, and environmental, tectonic, and diagenetic processes, together with evolutionary, biostratigraphic, and paleo-environmental significance of paleontology are presented. Additionally, this section also contains papers on marine geosciences, from molecular proxies related to climate to geophysical surveys. Last but not least, the third section on geochemistry is composed of 26 papers that are focused on sedimentary geochemistry and mineralogical characterization, magmatic and metamorphic processes and products, and the origin and exploration of mineral deposits. This book resumes the current situation related to the abovementioned topics mainly in the Mediterranean realm. The volume book is of interest to all researchers, practitioners, and students in the fields of geomorphology, sedimentology, and geochemistry, as well as those engaged in environmental geosciences, soil science, stratigraphy and paleontology, geoarcheology and geoheritage, marine geosciences, petrology, metallogenesis, and mineral deposits.

Book Description
Providing a balance between principles and practice, this state-of-the-art overview of geophysical methods takes readers from the basic physical phenomena, through the acquisition and processing of data, to the creation of geological models of the subsurface and data interpretation to find hidden mineral deposits. Detailed descriptions of all the commonly used geophysical methods are given, including gravity, magnetic, radiometric, electrical, electromagnetic and seismic methods. Each technique is described in a consistent way and without complex mathematics. Emphasising extraction of maximum geological information from geophysical data, the book also explains petrophysics, data modelling and common interpretation pitfalls. Packed with full-colour figures, also available online, the text is supported by selected examples from around the world, including all the major deposit types. Designed for advanced undergraduate and graduate courses in minerals geoscience, this is also a valuable reference for professionals in the mining industry wishing to make greater use of geophysical methods. In 2015, Dentith and Mudge won the ASEG Lindsay Ingall Memorial Award for their combined effort in promoting geophysics to the wider community with the publication of this title.

Book Description
Academic Paper from the year 2020 in the subject Geography / Earth Science - Regional Geography, grade: 1.0, University Of Abuja (FACULTY OF AGRICULTURE), course: AGRICULTURAL ECONOMICS, language: English, abstract: The study examined Socio-economic factors influencing adaptation strategies of flooding in Benue State, Nigeria. The study used purposes, multi-stage random, and convenient sampling techniques to select 315 farmers whose farms have been affected by flooding. Data for the study were collected from both primary and secondary sources using structured questionnaires, interviews, journals, data from NIMET and publications from other relevant agencies like BNARDA. The data collected were analysed using descriptive statistics, Maximum Likelihood Estimate (MLE). Economic losses caused by floods are rising in Africa. Both researchers predicted that if nothing is done by way of mitigation, crop yields would drop by 50% in 2017. This scenario is already manifesting in Asia and other tropical countries where the rural farming households depend on agriculture for their livelihood. The floods have adversely affected billions of people mostly through loss of farms and farmlands, rendering people homeless. In Nigeria, It is very common-place event to lose a large chunk of produce to flooding based on lack of adaptive strategies hinged on socio-economic factors of farmers. Farmers often lack the meteorological knowledge of what it takes to synchronize the adaptive strategies to the climatic events of flooding. It is estimated that tons of useful Agricultural produce are washed away during excessive rainfall (flooding) and pushes to great economic losses by the nation at large and farmers in particular. In Benue State, it is becoming increasingly difficult for farmers to engage in crop production activities during flooding without adequate adaptation strategies. These strategies are linked to Socio-economic factors and these Socio-economic factors create a lot of challenge if they are not properly understood because they present problems that will make farmers adopt the adaptive strategies slowly. The effect of these on Nigeria and theme state is lack of food sufficiency. It is very important to note that Benue State regarded as the food basket of the nation will have a major setback in fulfilling this note. The role stands out when farmers are able to churn out a harvest commensurate to the expectation of teeming population of the state and nation.
