The Jilling-Langalota iron ore deposit within the IOG is one of the best iron ore exposures hosted by Precambrian BIF in India. There are four ore bodies in the Jilling-Langalota area, namely, Jilling, Gang-aigora, Langalota and Jajang (Fig. 2 a). The ore bodies are bedded and lensoidal with variable dimensions.

In field, the magnetite quartzite iron ore formations are occurred as highly metamorphosed sediments with characteristic of banding. These are exposed as very hard and linear ridges (Fig. 1, Fig. 2), dark colored and strongly banded (Fig. 3f). The bandings are due to the occurrence of silica and iron-rich oxide minerals in alternate light and ...
