Travertine is a kind of limestone and it is also a by-product of natural artesian springs, known also as hot springs, as well as, caves the world over. Travertine is a natural, and porous stone. Travertine's pits and its rough texture is as a result of air bubbles and organic matter, and this is how travertine tiles come by its varying colours.

Exposure of sincere investors to a difficult investment experience; and Poor competitiveness of Nigeria relative to major countries in Africa as an investment destination. The crash in crude oil prices 'unanticipated' by the then Federal Government resulting in significant cash flow challenge and the desire to address this challenge, brought ...
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 Benin Flank (Olabode, 2006; …
A key regional player in West Africa, Nigeria accounts for about half of West Africa's population with approximately 202 million people and one of the largest populations of youth in the world.

2006). Marble is a metamorphosed limestone. Limestone and marble are carbonate rocks, dominated by the mineral calcite (CaCO 3). Nigeria is endowed with large deposits of limestone and marble located in all parts of the country. The limestone at Mfamosing, near Calabar, is the largest and the purest deposit in Nigeria. It is about 50 metres thick

The number of languages currently estimated and cataloged in Nigeria is 521. This number includes 510 living languages, 2 second languages without native speakers and 9 extinct languages. The official language of Nigeria, English, was chosen to facilitate the cultural and linguistic unity of the country post-colonization by the British.
Perceptions and exposure to climate events along Perception of climate change events along the maize-poultry value chain in Oyo State, Nigeria At the other extreme but in line with Fig 1, the feed mill node has the lowest share of actors perceiving all climate events apart from the increase in heat stress.
Crushed limestone provides a base for roads and asphalt concrete, as well as a ballast for railroads. Limestone creates geological formations that are perfect for storing petroleum. Limestone is a reagent in desulphurisation of flue-gas, which means that exposure of limestone to sulphur causes a reaction.
limestone is of moderate quality . The purest limestone documented in Nigeria is that of Mfamosing with a CaO content of 52 to 56% and a carbonate content 99% [2 – 3; 6; 12; 15]. This research work primarily focused on the quality assessment of the limestone deposits for the cement
Limestone deposit in Nigeria is majorly deposited in Cross River and Ebonyi states but can still be found in commercial deposit in Abia, Akwa Ibom, Anambra, Bauchi, Bayelsa, Benue, Borno, Edo, Enugu, Imo, Ogun, Ondo and Sokoto, making Nigeria the most richly deposited West African country when it comes to Limestone.. This is one of the mineral deposits in Nigeria that is of great proportion ...
Granite, coarse- or medium-grained intrusive igneous rock that is rich in quartz and feldspar; it is the most common plutonic rock of the Earth's crust, forming by the cooling of magma (silicate melt) at depth. Learn more about the properties and uses of granite in this article.
limestone. The base of the sequence is defined by the first appearance of marine limestone above the Bima Sandstone (Carter et al., 1963). The basal limestone is about 3m thick and consists of non-fossiliferous and shelly variety as well as Ammonites of Lower Turonian age (Reyment; 1956, 1965, Carter, 1963). 1.3 Fika Shale

Weathering is the breakdown of rock by physical, chemical or biological processes. Limestone areas are predominantly affected by chemical weathering when rainwater, which contains a weak carbonic acid, reacts with limestone. This causes the limestone to dissolve. Carbon dioxide from the respiration of animals (and ourselves) is one cause of increased carbon dioxide in the atmosphere.
the core log of the boreholes description as a guide, the reserve window of the limestone occurrence is put at ZK3 N-11, ZK1 So 10, ZK5 So 7, ZK9 So 9 to ZK13 So 3 on one trace and at ZK3 No 1, ZK9 So 0 to ZK13 So 3. This formed a polygon with 16 km length and 2 km width, making 32 sq. meters. The mineralized section has limestone core litholog
What is Limestone? Limestone is a sedimentary rock composed primarily of calcium carbonate (CaCO 3) in the form of the mineral calcite.It most commonly forms in clear, warm, shallow marine waters. It is usually an organic sedimentary rock that forms from the accumulation of …
Nigeria. Nigeria has one of the largest stocks of human resources for health (HRH) in Africa but, like the other 57 HRH crisis countries, has densities of nurses, midwives and doctors that are still too low to effectively deliver essential health services (1.95 per 1,000).
the subaerial exposure, the unconformity (sequence boundary) is a Type 1 unconformity hence the Ashaka Cement Quarry section is a Type 1 sequence. The basal Kanawa Member (unit 3, Fig. 4) found above the ferruginous crust in the quarry is a calcareous sandstone (Zaborski, 1995) and the basal limestone is quartz- rich.
