Abstract

NORTHERN ANOMALY IRON DEPOSIT, as one of the largest reserves at BAFQ AREA, is situated at a distance of 10 kilometers on the North West of Choghart iron mine. The host rocks of this deposit are dominantly composed of hypabyssal to extrusive igneous rocks of acidic nature such as rhyolite, trachyte and microgranite that are metasomatised to a great extent. The effects of metasomatic phenomenon has resulted in fundamental changes in the mineral composition of the host rocks in such a way that the basic minerals. Quartz and feldspar have recrystallized and new metasomatic ones viz. tremolite, actinolite, chlorite, epidote and calcite have been formed.The main mineral of the deposit is magnetite that is converted into hematites in shallow depth as well as surficial portions of the ore body.Minute particles of pyrite are scattered throughout the ore. The results of mineralogical studies revealed the presence of at least two phases of pyrite formation in this ore deposit. X-ray diffractometry on samples taken out from a depth of 285-300 meters showed that mineral TAENITE occurs in some of the borehole samples as an exsoluted crystal phase in association with magnetite (on the octahedral faces of magnetite crystals). Normally, TAENITE is found in iron meteorites, the sudden release of pressure during magmatic phases can result in its separation from magnetite.The occurrence of TAENITE considered along with the geochemical investigations, are both indicative of low-grade low-phosphorous apatitic iron deposit of magmatic origin.
