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 ...

Since times of the Jones (1934) the Iron ore deposits of Orissa and Jharkhand have received great attention due of their being high grade and large size. Here mining is done by simple quarrying. If the present day production of a very high scale, these ore deposits continue at this rate, then they would be exhausted in the near future.

Abstract The iron formation of Bonai-Keonjhar belt, Keonjhar district of Odisha comprises a promising horizon of Banded Iron Formation (BIF) which is situated in the western flank of North Odisha Iron Ore Craton (NOIC). In this investigation, major, trace and REE chemistry of the Banded Iron Formation of the area are utilized to interpret the …

The high-grade ores are characterized by high Fe (>62 wt %), low Al 2 O 3 (1.5–2.5 wt %), low SiO 2 (2.0–4.5 wt %) and low P (<0.06 wt %). Detailed field studies and laboratory investigations on the ore mineral assemblages suggest that the mineralization of high-grade iron ores at KMIOD is controlled by three major parameters, i.e ...

The production of iron ore (excluding ROM) con-stituting lumps, fines and concentrates was at 192.08 million tonnes in the year 2016-17, showing an increase of about 21% as compared to that in the preceding year. IRON ORE. There were 296 reporting mines in 2016-17 as against 330 in the previous year.

The difference in approach to the answer to these questions has been reflected in the classification of cherty iron-formations. Shatskiy's ( 1954) ideas concerning the classification of volcanogenic and volcanogenic-sedimentary formations greatly influenced the development of ideas concerning Precambrian iron-ore formations.

Last update 7 February 2023. India has one of the richest inventories of Precambrian geological record on Earth. Notwithstanding this, much of the Indian subcontinent remains unexplored compared to other ancient cratons in North America, Australia, Brazil Africa, and North China. There are five Archean cratonic nuclei in India (the Aravalli ...

The Precambrian geologic history of peninsular India covers nearly 3.0 billion years of time. The Peninsula is an assembly of five different cratonic nuclei known as the Aravalli-Bundelkhand, Eastern Dharwar, Western Dharwar, Bastar and Singhbhum cratons along with the Southern Granulite Province.

Contracting the old term 'iron-bearing formation' used in early reports on the Lake Superior iron ore range, James (1954) formally defined an ironlormation as "achemical sediment, typically thin-bedded or laminated, containing 15% or more iron of sedimentary origin, commonly but not necessarily containing layers of chert." The

Numerous iron ore deposits are hosted within the Meso to Neo-Archean banded iron formations (BIFs) extending across the Singhbhum-Orissa Craton, eastern India. Despite the widespread distribution of BIFs, which forms part of the iron ore group (IOG), heterogeneity in their grade and mineral composition is occasionally observed …
