Dahomey basin in Nigeria. The limestone is about 15m thick at the Ewekoro quarry while at Sagamu quarry, it is about 20m. It is thickly bedded and colour banded. Apart from the quarry exposures, outcrops are rare and are intercepted in several boreholes west of Ijebu Ode. It is Palaeocene in age and associated with shallow marine
The Federal University of Technology, Akure, Nigeria Correspondence psolafuta.edu.ng ABSTRACT The limestone part of the Ewekoro Formation as exposed at a mining site in Sagamu was subjected to lithostratigraphic and geochemical studies. The study aims at a more detailed lithologic description including major
Limestone /Marble deposit. Of recent however, limestone/marble and other marine sediments (mudstone,calcareous marl.shale and carbonaneous limestone,have been found at Eleja,Biribiri,Babanloma and Fufu in Ilorin South LGA. The database has added support for theorizing about how the recent oil seepage came about.
The northern part of the basin in Nigeria is the exposure of the Abeokuta group which unconformably overlying the basement while towards the sea, there is a progressive increase in the thickness of chemical and biochemical sediments such as gypsum, glauconite, limestone and other associated marine deposits which is then capped by coastal sands ...
Mar 01, 2020 The limestone beds on the Benin Flank of southwestern Nigeria are of importance to economic and industrial growth of Nigeria. Little attention has been paid to detailed mineralogy, diagenesis and depositional setting of the carbonate rocks because outcrops of significantly thick Late Cretaceous-Early Paleogene limestone are poorly exposed on the
Oct 13, 2016 Limestone subjected to exterior exposures deteriorates due to weathering or the natural effects of wind, rain, and thermal change. Limestone is extremely durable. It does, however, absorb water and, since it is a carbonate rock, it is highly reactive when exposed to acids or even mildly acidic rain water, and it can suffer substantial ...
Apr 09, 2019 Dolomite deposits are one of the Nigeria mineral resources, similar to Limestone in terms of exposure to pressure and heat. It is formed from the sedimentary rock.

Detailed fieldwork in parts of the Benin (Dahomey) Basin SW, Nigeria has allowed the recognition of sedimentary successions deposited in different continental depositional environments interpreted as fluvial sedimentation characterised by abandoned channels and subaerial exposure features. The lithofacies recognised are conglomerates, debris flow deposits, very

Analysis of the stacking sequence of the facies can be used to determine the relative importance of the controls exerted by climate, tectonism, autocyclicity and sea-level movements (Fig. 4).
Nov 12, 2021 This paper presents a new depositional model for the Amasiri Sandstone of the southern Benue Trough, Nigeria. Variants of facies and facies relationships suggesting fluvial, storm, and sediment gravity processes gave rise to controversies in the interpretation of environments of deposition for the formation. However, newly exposed sections in the quarries
Jan 01, 2017 Though exposures are rare, the formation consists mainly of dark gray to bluish gray shales, with occasional admixtures of clay, ironstone, thin sandstone bands, and limestone intercalations. The most conspicuous lithofacies components of the formation are three sandstone bodiesthe Ebenebe, the Igbaku, and the Umuna Members.
Limestone may contain trace amounts of free crystalline silica. Prolonged exposure to respirable free silica can aggravate other lung conditions and cause silicosis, a disabling and potentially fatal lung disease. Exposure to limestone dust may cause irritation to the moist mucous membranes of the nose, throat, and upper respiratory system. It may

limestone, which he correlated with the Imo shale and to which he assigned a Paleocene age. In addition, he estimated the thickness to be greater than 14m. This was because the exposure of Ewekoro, where the limestone is quarried extensively is not representative. Borehole records however show that the limestone in this
