Dec 17, 2011· The Sekarna Zn–Pb deposit is located in Central Tunisia at the northeastern edge of the Cenozoic Rohia graben. Mineralization comprises two major ore types: (1) disseminated Zn–Pb sulfides that occur as lenses in sedimentary phosphorite layers and (2) cavity-filling zinc oxides (calamine-type ores) that crosscut Late Cretaceous and Early Eocene limestone.

SEDEX: The Biggest Lead and Zinc Deposits in the World

Oct 17, 2019· SEDEX (SEDimentary Exhalative) deposits are one of several types of sediment-hosted lead-zinc deposits. Rich accumulations of lead, zinc and silver are found in the ore minerals sphalerite (zinc sulfide) and galena (lead sulfide) deposited between thin layers of marine sand, silt and mud in sedimentary basins.

and paragenesis of the mineral deposits. Orajaka (1965) studied the lead-zinc deposits at Enyigba, Ameri and Ameka and observed the abundant development of gangue and ore minerals in partially filled vugs and cavities. On the basis of the observed features, he suggested cavity-filling processes of deposition from a telemagmatic source.

Tunisia Resources and power Britannica

Tunisia Tunisia Resources and power: Tunisia’s natural resources are relatively meagre. Until the discovery of petroleum, the principal mineral resource was phosphate; of this, one-third is exported, and the remainder is used by domestic chemical industries. Fertilizer is also an important export. Other major mineral resources are zinc, lead, barite, and iron.
