Ferruginised Metapelites of The Kazaure Schist Belt, Northwestern Nigeria

Aliyu Abdu Ibrahim, Ismail Bala Jibril.

Abstract
ABSTRACT
Field, petrographic and geochemical evidence show the occurrence of ferruginised metapelites (FMP) in the Kazaure Schist Belt (KZSB). The KZSB consists predominantly of quartzites, pelitic metasediments, and metaconglomerates. Minor rocks include metavolcanics and iron formations (Banded Iron Formation and ferruginised metapelites). The FMP occurs as narrow bands associated with quartzites and phyllites. Magnetite as euhedral to subhedral crystals together with subordinate anhedral hematite forms the Fe band. The Fe content of the FMP (14.54 – 82.8 %) is comparable to that of banded iron formations in the schist belt. It contains lesser amounts of Mn (0.07 – 17.83 %), Ca (0.067 – 1.25%), and the lithophile elements average values: K (1.21 ppm); Rb (89.89 ppm); Sr (190.78 ppm). It is envisaged that the FMP developed from the alteration of the metasediments entrapped as a kind of tectonic mélange as a result of late tectonic brittle deformation and activity of fluids rich in iron.

Key words: Banded Iron Formation, ferruginised metapelites Oxide facies, Tectonic mélange, Silicate facies.
