Lead Ore In The Benue Trough

Lead-Zinc-Barytes mineralization in the Benue Trough ...

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.

Origin of lead-zinc mineralization in the southern Benue ...

Mar 01, 1985 · 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.

in terms of the ore bearing rock groupings, while the review of Pb-Zn mineralization is intended to give cre-dence to findings in previous studies that the Benue Trough houses some of the complex sulphide minerals in-cluding the lead-Zinc deposits under study [8].

Contrasting styles of lead-zinc-barium mineralization in ...

In the Lower Benue Trough of Southeastern Nigeria, lead-zinc-barium mineralization occurs as widely distributed . epigenetic fracture-controlled vein deposits which are restricted to Albian – Turonian sediments. Detailed field studies carried out in Ishiagu, Enyigba-Ameki-Ameri, Wanikande-Wanakom, and Gabu-Oshina which together constitute the

GEOLOGY AND MINERALISATION IN THE ALBIAN SEDIMENTS …

ABSTRACT : The epigenetic lead-zinc-barite fluorite deposits of the Benue Trough are localized in N-S trending fractures developed within the lower Cretaceous Albian shales, limestone and arkosic sandstones. The mineralogy of the sulfide deposits consists mainly of

Nigeria Export: Product Profiles:Lead Ore

The Abakaliki Lead-Zinc is believed to be of hydrothermal origin emplaced at a low temperature of about 140°C and it is made up of primarily four lodes namely Ishiagu, Enyigba, Ameri and Ameka in the lower Benue Trough located in Ebonyi State. Other locations of lead ore in Nigeria include Bauchi, Gombe, Plateau, Nassarawa and Zamfara

A review of the geology of the Benue Trough, Nigeria ...

LEAD-ZINC MINERALISATION OF THE BENUE TROUGH One of the major features of the Benue Trough is the central zone of lead-zinc mineralisation which is about 80 km wide and extends from Abakaliki in the south to Zurak in the northeast, a distance of about 560 km (Fig. 1).

Mineralogical, textural and paragenetic studies of the ...

The mineralization is considered to be epigenetic and vein formation appears to have accompanied the Cenomanian tectonic event in the Benue basin. INTRODUCTION The lead-zinc-copper veins at Abakaliki and Ishlagu districts in the lower Benue Trough of Nigeria are the largest base metal deposits within the Lower Cretaceous (Albian) sedimentary sequences of the Benue rift structure.

Geology and mineral resources of the Lower Benue Trough ...

Lead – Zinc: Deposits of zinc and lead minerals in the form of their ores of sphalerite and galena respectively often associated with barytes mineralization in …

Lead ore Importation, Storage and Export From Nigeria ...

The occurrence and distribution of Lead ore in Nigeria mainly around the benue trough. Economic Pb-Zn mineralization is restricted to the Southern parts of the Trough. Associated with the Pb-Zn ore are chalcopyrite, siderite, azurite, malachite and marcasite.

(PDF) Review of the occurrence and structural controls of ...

Lead-zinc-fluorite-barite vein ore-bodies occur in the Benue Trough within the Albian sequence of this intracontinental rift structure. The veins are distributed in a series of N/S and NW/SE ...

Assessment of Cadmium and Lead Distribution in the Outcrop ...

studies have been reported on the lead–zinc mineralization in the Southern Benue Trough [27,31,35,40,41], there is paucity of information on cadmium and lead distribution in the outcrop rocks of Southern Benue Trough of Nigeria. from outcrops of all lithologic units from Abakal

Contrasting styles of lead-zinc-barium mineralization in ...

Mar 01, 2017 · In the Lower Benue Trough of Southeastern Nigeria, lead-zinc-barium mineralization occurs as widely distributed epigenetic fracture-controlled vein deposits which are restricted to Albian – Turonian sediments.

Genesis of the Lead -Zinc Mineralization, Upper Benue ...

Abstract: The lead – zinc ores in the Upper Benue Trough occur as veins within the Albian Bima sandstones. The homogenization and freezing temperatures determined in sphalerites indicate that they were precipitated from a moderately hot mineralizing fluid (176 o …

GEOCHEMICAL STUDIES OF MINERAL BEARING ORES FROM …

the Trough, associated with the Pb–Zn ore are chalcopyrite, siderite, azurite, malachite and mascasite. Upward to the middle and upper regions of the Trough are important deposits of salt, baryte, limestone and fluorite as well as argentiferous galena and gypsum. All …

Mar 01, 2017 · The general characteristics of the Benue Trough lead-zinc-barium deposits, therefore, are: (1) the ores are epigenetic. (2) They are hosted in carbonaceous shales and siltstones of Albian--Turonian age. (3) They are closely associated (spatially) with igneous intruszions. (4) Ores occur as veins which may extend up to 2km in length.
