2020-7-10 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

2001-4-11 Lead-zinc mineralization in the upper Benue Trough is confined towell-defined steeply dipping fractures and faults striking inan N-S direction. A close examination of the mineralized structures of abandoned mine workings revealed that the strike length of the veins varies from a few meters with thickness ranging from

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. Fracturing and jointing are intense in the areas of mineralization.

1990-1-1 The lead-zinc mineralization of the Benue Trough, distributed along the main anticlinal structures, forms a belt running for about 500 km. They occur in tensional submeridian fractureas resulting from the tectonic regime prevailing during the early stage of the Benue Trough infilling.

2019-6-25 Zn mineralization is attributed to a sedimentary geological model based on the geotectonic setting, the mode of occurrence and fluid-inclusion characteristics. This model is noted to connate brines set Abstract Very low frequency Electromagnetic (VLF-EM) exploration over the Ishiagu area of Abakaliki Basin, Lower Benue Trough, Nigeria was carried out to determine the Pb-Zn mineralization in the

2018-6-1 Distribution of lead-zinc-baryte mineralization along the Benue Trough (Inset sketch map of Nigeria showing the Benue Trough) (modified from Ene et al., 2012). Although a great deal of research has been devoted to determining the source of the ore components ( Maurin and Lancelot, 1987 , Dada et al., 2015 , El-Nafaty, 2015 ), the source of the metal (Ba) is still poorly constrained.

2019-6-25 Lower Benue Trough during the early Cretaceous separation of Africa and America [6]. The Pb-Zn deposits in Ishiagu area appear to be the southern limit of mineralization in the Benue Trough and the Pb-Zn mineralized zone extends over a distance of 500 km in a narrow belt from Ishiagu in the lower Benue Trough to Zurak in the upper Benue

The Benue Trough galena-sphalerite-baryte occurrences are formed by open space filling in faults, hence they are generally considered to be epigenetic fracture filling deposits (Ezepue 1984; Oha et al. 2017). Oha et al. (2017) summarized the main characteristics of the lead-zinc-barium mineralization in the Benue Trough as (i) the ores

The Gboko Formation has been described as the oldest lithologic unit . in the lower Benue Trough, (Reyment, 1965; Ramanathan and Nair, 1984). The Gboko Formation rests directly on the Precambrian granitic basement,

Introduction. The lead-zinc-barium deposits of the Benue Trough have been known since colonial times. Initial exploration efforts mainly by geologists from the Geological Survey of Nigeria (GSN) between the late 1930's and the early 80's led to the discovery of some small to medium-sized deposits in a fairly extensive belt stretching from the southeastern part of the Trough to the northeastern ...

Lead-zinc mineralization is dominant in the Albian Shales with fewer occurrences in the Turonian strata. No mineralization has been reported in post-Turonian sediments. Farrington (1952) referred to the trough succession as geosynclinal and indicated the absence of graben faults at trough margins.

Yolo lead-zinc mining district is an important area in Gongola Sub-basin of the Upper Benue Trough with paucity of rocks outcrops but abundant termite mounds. The termite mounds and their adjoining surface soils were analyzed for Pb, Zn, Ti, Cu, Sb, As, U, Cr, Zr and Li in an attempt to test their effectiveness in defining favorable areas for lead-Zinc mineralization in the Upper Benue Trough.
