Here, we present a geochemical study of the barite deposits from 11 cold seeps from the northern Gulf of Mexico (GOM) continental slope. The barite samples were collected from early 1990s to 2007 at water depths between 510 m and 2230 m (Table S1; Fig. 1).The barites were analyzed using a combination of petrography, mineralogy, and …
Nigeria, there are vein and cavity-type deposits of barite and filling types. These deposits are usually found in a variety of rocks, including sandstone, migmatite, limestone, …
The BaO contents of the barite ores range between 62.99 and 59.35 wt.%, whereas their SrO levels are between 1.02 and 2.28 wt.% (Table 1). The high presence of strontium in barite deposits is related to the similarities in the atomic radii of strontium and barium, which Fig. 3.
However, considering their rare earth element compositions, barite samples surround the field for seawaters when plotted on Ce N /Yb N-Yb N and Ce N /Sm N-Ce N /Yb N diagrams. Fluid inclusion data obtained from the barites indicated a formation from a fluid with low salinity (0.9-1.6 wt.% NaCl eq.) at homogenization temperatures between …
Barite (barium sulfate, BaSO ) is vital to the oil and gas. 4 industry because it is a key constituent of the mud used to drill oil and gas wells. Elemental barium is an additive in optical glass, ceramic glazes, and other products. Within the United States, barite is produced mainly from mines in Nevada.
Barite deposits in Nigeria are found in veins and cavity fillings hosted by varieties of rocks and are largely used by the oil and gas industry during drilling operations as a drilling mud weighting agent to balance the reservoir pressure and prevent blowouts …

It shows that the current mineralization of barite in Nigeria is across the N-S axis. The barite deposits in Nigeria located in the North-East are specifically along the Benue Trough, which includes states like Benue, Taraba, and Adamawa; towards the North (Nasarawa, Plateau, and Gombe states) and to the South fringe of Cross River [20, [23 ...
The worth of Nigeria's paint industry is projected to hit $377 mn (N135. 80 billion) by 2025. Again, barite is quite useful here. Barite is a replacement to basofor, crypton, titanium dioxide, and monox which are used for filling. It is very useful in regulating the thickness of the paint.
In Nigeria, most barite deposits are vein and cavity filling type of deposit and this type of deposit may be hosted by different rock types such as sandstone, limestone, migmatite, shale, mudstone and porphyritic granite. ... For decades the Nigeria economy has depended solely on the sale of crude oil but with the recent downturn in the oil ...
The drift characteristics of the gravimeter are very low throughout the entire field survey with average drift rate of -0.000001014 mGal/s. Elevation within the study area range between 115 m (377 ft) and 130 m (426 ft) above mean sea level. The results of the gravity survey are presented as anomaly profiles and maps.

in Nigeria and one of such minerals is barite. Barite occurs in veins, stratiform beds and residual deposits. Stratiform beds are the largest global deposits currently mined in the …
Over the years, oil and gas industry in Nigeria has been depending mainly on imported barite for drilling operations, whereas the country has huge deposits of barite.
About 34 minerals deposits have been identified in Nigeria and one of such is barite ore. Barite has many applications; the most significant of it is its usage by the oil companies when drilling for crude oil or petroleum. ... The project involves the mining, milling and packaging of different sizes of barite ore for sale to oil and gas ...
Barite is an industrial mineral that is used in drilling mud and making other engineering products [17–19]. The mineral is found in commercial quantities in Cross River, Benue, Nasarawa, Plateau, Taraba, Adamawa Zamfara, and Gombe states of Nigeria [20–23]. The exploration of Nigerian barite deposits is primarily by ASM using
Barite deposits of the Lasbela District, Balochistan, hosted in the Ferozabad Group (FG) of Jurassic are relatively pure and have BaO value ranging from 40.18 to 60.91 % with minor amounts of Sr ...

Gravity and electromagnetic methods were combined to characterize known veins and possibly unveil other concealed veins in Tunga, Northeastern Nigeria. Barite occurs in the study area as vein deposits hosted in clean sandstone rocks. Laboratory analyses of samples show average specific gravity of the variety to vary between 3.16 …
Barite deposits in Benue State is in the form of vein and cavity filling which occurs as a result of hydrothermal solutions during Santonian deformation, depositing barite in the fissure formed (Nigeria Geological Survey Agency, 2011). These deposits are found in Markudi, Gboko, Ushongo, Vandeikya and Guma Local Government Areas of Benue …

Despite all the barite deposits in Nigeria, which is approximately 15 million tonnes, it still imports barite from other countries for use in the drilling of oil and gas in Nigeria. This of course brings about unnecessary expenses been incurred by the government of Nigeria. Some of the challenges faced with the mining and processing of the ...
The Ghar Roubane barite deposit might well stand as an epigenetic vein occurrence, with open-space filling veins. It occurs in the form of massive and replacement ores stretching across faults and fractures of Paleozoic granite and Liassic limestone host rocks.
