Contrasting styles of lead-zinc-barium mineralization in the Lower Benue Trough, Southeastern Nigeria

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...

description 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 four main areas of mineralization in the Lower Benue Trough, show that mineralization appears restricted to NW-SE and N-S fractures while the more common NE-SW fractures are barren. Apart from the Enyigba area, igneous bodies are found in the vicinity of the ore deposits while in the Wanikande area, barite veins and veinlets were observed to be closely interwoven with intrusive bodies. The host lithologies are highly varied, ranging from shales to siltstones, sandstones and occasionally igneous bodies. The ore assemblage also varies remarkably, with lead:zinc:barium ratios ranging from approximately 3:1:0 at Ishiagu, to 2:1:0 at Enyigba, 1:0:2 at Wanikande and nearly 100% barite at Gabu-Oshina. Thus, there is a remarkable increase in barite content from the southwest (Ishiagu) to the northeast (Gabu). The characteristics of the ore deposits roughly fit the base metal type mineralization known as clastic dominated lead-zinc-barium deposits. This study forms part of a mineral potential database which is invaluable for any detailed exploration venture in the area.

Estudios de campo detallados realizados en Ishiagu, Enyigba-Ameki-Ameri, Wanikande-Wanakom y Gabu-Oshina (que conforman las cuatro áreas principales de mineralización en la parte baja de Benue Trough) muestran que la mineralización aparece restringida a fracturas NW-SE y N-S, mientras que las fracturas NE-SW, que son más comunes, aparecen estériles. Aparte del área Enyigba, los cuerpos ígneos se encontraron junto a los depósitos de minerales, mientras en el área Wanikande se observaron vetas y vetillas de baritina que están prácticamente entretejidas con cuerpos intrusivos. Las litologías sede son ampliamente variadas, y van desde esquistos a limolitas, areniscas y ocasionalmente cuerpos ígneos. El ensamble de la mena también varía con proporciones de plomo:zinc:bario que van aproximadamente desde 3:1:0 en Ishiagu, 2:1:0 en Enyigba, 1:0:2 en Wanikande y cerca del 100 % de baritina en Gabu-Oshina. Por ende, hay un incremento importante en el contenido de baritina desde el suroeste (Ishiagu) hacia el noroeste (Gabu). Las características de los depósitos minerales se enmarcan aproximadamente en el tipo de mineralización de base metálica, conocido como depósitos plomo-zinc-bario de dominación clástica. Este estudio hace parte de una base de datos de minerales potenciales que es invaluable para una exploración detallada en el área.application/pdfspaUniversidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Departamento de Geocienciahttps://revistas.unal.edu.co/index.php/esrj/article/view/39703Universidad Nacional de Colombia Revistas electrónicas UN Earth Sciences Research JournalEarth Sciences Research JournalOha, Ifeanyi Andrew and Onuoha, Kalu Mosto and Dada, Silas Sunday (2017) Contrasting styles of lead-zinc-barium mineralization in the Lower Benue Trough, Southeastern Nigeria.
