Nigeria in contrast to the occurrences reported within the Cretaceous Benue Trough. The quality of the barite is here studied based on international specifications such as concentration of BaSO 4 (between 92-95%), degree of whiteness and reflectance, Specific gravity (4.2 and above), and concentration of iron oxide minerals, moisture
The epigenetic Pb-Zn deposits of the southern Benue Valley (Nigeria) are localized within Cretaceous sediments of an intracontinental rift basin. Fluid inclusion studies of vein minerals from the Abakaliki and Ishiagu orebodies show that sphalerite and quartz were deposited at relatively low temperatures (102–175 °C), with ore-fluid salinity mostly in the range of 17–25 equiv. wt% NaCl ...
the Calabar Flank which is in the lower Benue Trough, the outcrops are widespread but mineralization is generally concealed. Barite occurrence has been studied in twenty two localities and the host rocks include sandstones, shales, dolerites, granite and gneiss. Shales and sandstones have the greatest occurrence of barite. The mineral occurs as
Benue Trough and in the Cretaceous sediments. Detailed paragenetic relationship of the barite in relation to the Benue trough metallogenic province (Olade, 1975; Ogbeide, 1984; Ogundipe, 1987) is however not studied in this work. REGIONAL GEOLOGY OF BENUE TROUGH Location The Benue Trough is a rift basin in the central
The Benue Trough is Nigeria's main but not exclusive source of baryte mineralization. Oden (2012) reported that occurrences of baryte are found in various localities of eight states within the Benue Trough. They include Alifokpa, Gabu and Osina in Cross River State and Ishiagu in Ebonyi State in the Lower Benue Trough; baryte fields occur in ...
Benue Trough and was able to delineate zones characterized by particular mineral resources. Similarly, Akande et al (1992) also carried out a systematic study of the formation of Lead-Zinc-Fluorite-Barite deposit of the Benue Trough. Hydrogeologically, Offodile (1992) delineated water bearing aquifer and discuss the water
According to Akande et al.(1988) the lead-zinc copper –barite deposits in the Benue Trough resulted from the hot banal fluids leached metals from arkoses sediments and later precipitated them as metal sulphides in Cinemania fractures of the Asu River Group. Detailed exploration to …
The occurrence of barite in parts of Middle Benue Trough was first reported by [1] in his memorandum, Geological Survey of Nigeria Report No. 1266 and …
ABSTRACT: The Azara barite deposits formed parts of Middle Benue Trough which is located in an elongated rift (or faulted-bounded) mega structural depression trending NE-SW to a length of over 1000 km and a width of 100 km.Petrological and geochemical investigations of Azrara barite …
The Minister recalled that barite is among the seven strategic minerals designated for top priority development by the Nigerian government. He said Barite occurs within the Benue Trough (Benue, Taraba, Adamawa States) and its fringes to the north (Nassarawa, Platueau and Gombe States) and the Southern fringe (Cross River State).
"Barite is a mineral used in the oil and gas industry and Nigeria has the mineral all over the country, especially in Benue, Taraba, Adamawa, Nasarawa, Plateau, Gombe and Cross River states. He said that 50 bags of barite milled would be showcased at the inauguration, adding that the mineral meant for the oil and gas industry was produced to ...
12%Abstract Several barite deposits have been reported to occur in Nigeria within the Benue Trough, one of the West Central African Rift Systems (WCARS) considered variously as an aulacogen, strike-slip or pull-apart basin. In spite of these occurrences and the high local and international demand for barites, Nigerian barite is yet to find a place even in its local market probably …
Barite occurrence in Nigeria is majorly in veins and cavities and it occurs in large deposits in the Benue Trough. It exists along with gangue minerals. It is found in nine states in the country with an estimated reserve of 22,298,843 tonnes on an average vein depth of 20 m and a specific gravity of 4.2.
of contributing immensely to the growth of the Nigerian Economy is Barite (BaSO 4). Barites mineralization occurred both in Basement complex and in the Sedimentary Basins of Nigeria and is also occurred within the entire length of the Benue Trough.Barite occurrence in Gombe Inlier is one of the neglected and under studied Barite in Nigeria.
The Benue trough is Nigeria's main, but not exclusive source of barite mineralisation. There are at least ten barite fields in the trough, each containing swarms of veins or concordant ...
The Benue Trough of Nigeria is a sedimentary basin that extends from the Gulf of Guinea in the southwest to the Chad Basin in the northwest for about 800 km in length and 150 km in width. Lead-zinc-barytes occurs in almost the entire length of the Benue Trough. Lead-zinc-barytes mineralization in the Trough is believed to be hydrothermal in origin and is associated with brine springs.

In the Lower Benue Trough, basin formation was as a result of at least two tectonic phases. The first tectonic phase was assigned Aptian – Santonian by Short and Stauble (1967) and Albian – Santonian by Murat (1970). Simpson (1954) recorded that the sediments of the Abakaliki-Benue Trough underwent a minor folding phase during the Cenomanian
Barite is one of the many solid minerals that are found in commercial quantities in Nigeria. Barite which is simply barium sulphate (BaSO4) occurs in large deposits in the Benue Trough. Over 7.5 million tonnes of barite have been identified in Cross River, Benue, Taraba and Bauchi States of the upper and middle Benue troughs.
Tattam 1930 made the earliest report on lead-zinc-barite mineralization in the Lower Benue Trough, highlighting the mode of occurrence and mineralogy of the lead-zinc deposits in the Abakaliki area. This was followed by extensive surveys to determine the extent of mineralization in the Abakaliki and Ishiagu areas, ( McConnel, 1949 ; Mc Kay ...
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 ...

The main stages of tectonic evolution of the Benue Trough are well documented in the stratigraphic succession, basically comprising three depositional sequences: an Albian-Cenomanian pyroclastic, paralic, shallow marine, and fluviatile sequence corresponding to the graben and transitional tectonic stages; a Turonian-Coniacian paralic, marine and fluviatile sequence that resulted from ...
The Benue Trough is a Cretaceous sedimentary basin, an elongated rift approximately 1,000km long and 50-150km wide, and is Nigeria's main source of barite mineralisation across eight states in the north and south-east of the country: Nasarawa, Plateau, Taraba, Adamawa, Benue, Cross River, Ebonyi and Gombe (see map).
the barite discoveries in the Benue Trough were made by prospectors who noted fragments of the mineralization in the heaps that farmers made for their crops. The study area is situated within Benue River depression SSE of Awe town. The Awe formation in …
Lead-zinc-fluorite-barite veins in the lower and middle Benue Trough (Nigeria) are located within the Lower Cretaceous (Albian) carbonaceous shales, limestones, and arkosic sandstones of this intracontinental rift structure. The veins in the lower Benue Through consist of sphalerite + galena+marcasite ± chalcopyrite ± barite in a gangue of siderite and quartz hosted by carbonaceous …

Benue Trough, the sulfur isotope in the deposits of the Southern Benue contain more of the lighter sulfur isotope (32 S) than that of the Central and Northern Benue Trough deposits which is the main reason for absence of barite in the deposit of the study area unlike the Central and Northern Benue deposits.
Keywords: Benue Trough, Barite veins, Azara fields, sandstones, extension joints, crack-seal mechanism 1. Introduction Earlier literature on the Nigerian barite mentions the mineral as a gangue in galena and sphalerite veins (Farrington, 1952; McConnel, 1949b). But as from 1951, the barite resource of Nigeria started gaining recognition.
