Abstract:

The Pur-Banera belt is one of the largest iron ore deposits, which is part of the Bhilwara Supergroup. The Pur-Banera belt is located in the central part of the Bhilwara district trending in NE-SW direction, where the geological settings, mineralization, and genesis of iron ore (mainly hematite and magnetite) study has been carried out. The major litho-units of the area are conglomerate, garnetiferous mica-schist, calc-schist, amphibolite, calc-gneiss, calc-silicate marble, and banded iron formation including Banded Hematite Quartzite (BHQ), Banded Magnetite Quartzite (BMQ), and carbonate rocks with associated sulfide mineralization. Iron deposits of the area comprise of iron minerals like hematite and magnetite. Quartz constitutes the silica forming bands alternate with iron minerals.
Geologically in the study area, the hematitemagnetite quartzite and carbonate rock inter-bedded with biotite garnet schist, calc-schist, and calc-gneiss occur as a persistent horizon. The hematite and magnetite quartzite consists of two individual bands separated by partings of biotite-sericite schist and are folded. The two prominent bands representing a line of asymmetrical fold forming a chain of hillocks are exposed from Tiranga in the south to Dhulkhera in north and Suras in the south to Dhulkhera in the north and also from Jipiya in the south to Devpura in the north. The hematite-magnetite quartzite is cherty at places and fractures are filled by secondary silica.
The BHQ and BMQ occurring in banded form and showing sedimentary structure like bedding and flame structure. Banded iron ore occurs with quartzite and another meta-sedimentary sequence that indicating metamorphism took place after a sedimentary deposit. Therefore, it can be concluded that the iron ore in the present area of investigation belongs to metamorphosed sedimentary type deposits. The paper discusses the geological setting of the area, mineralisation, and genesis of iron ore that exist there.
