Structural Controls and Mineralization Style of Baryte Deposits in the Azara Area, Central Benue Trough, Nigeria: Implications for Mineral Exploration
Baryte mineralization in Nigeria’s Azara area of the central Benue Trough is hosted primarily in Cretaceous siliciclastic rocks and is tightly linked to a NE‑SW structural corridor that coincides with an anticlinal crest. Integrated surface mapping, satellite‑image processing, airborne radiometric surveys and drill‑core analysis reveal steep, bedding‑discordant veins forming massive fissure‑fill lodes, breccia infill, stockwork and cavity fills. The ore assemblage includes baryte, siderite, minor chalcopyrite‑pyrite and later‑stage sphalerite, indicating a multi‑stage, fold‑related hydrothermal system. Anticlinal crests, vein‑set intersections and dilational jogs emerge as the prime exploration targets.
