Manganese ores in India are being exploited since the past hundred years. Continuous exploitation of shallower and massive deposits led to searching for further occurrences and also necessitated application of geophysical methods. Geological survey of India since 1940s, has been exploring for manganese deposits in various parts of the country …

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 …

Depending on the objectives and scales of operation all the known geophysical methods are being employed in the Geological Survey of India. As mineral exploration is of paramount charter of Geological Survey of India (GIS) under M-II, geophysical surveys occupy important role.

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 …

In the following discussion, the applicability of geophysical methods to geoenvironmental studies of ore deposits is reviewed. Details of geophysical techniques are not emphasized; these are covered in standard texts (Society of Exploration Geophysicists, 1966; 1990) and have been summarized in Hoover and others (1992).

Our study interprets large-scale gravity data to delineate concealed banded iron formation (BIF) iron mineralization in India's Rajasthan province. The study area belongs to the Bharatpur, Dausa, and Karauli districts of Rajasthan.

The research area has the iron ore potential which is estimated to be localized below the AB trajectory with a length of 164.85 meters, a depth ranging of 1.709 - 31.909 meters, and magnetic susceptibility value of 0.0122 cgs unit which interpreted as sand inserted with silt and clay containing iron ore grains significantly from the formation ...

Geological Survey of India (GSI) will soon take up the ambitious National Airborne Geophysical Mapping project covering 8 lakh sq kms including the Obvious Geological …

The main objective of this research was to use ground magnetic survey to delineate shear zone and iron ore deposit within the Neoproterozoic rocks of Mutomo-Ikutha area of south eastern Kenya.

Our study interprets large-scale gravity data to delineate concealed banded iron formation (BIF) iron mineralization in India's Rajasthan province. The study area belongs to the Bharatpur, Dausa, and Karauli districts of Rajasthan. We measured 1462 gravity readings to understand the rock types, depth and geometry of the different rock …

While augmenting iron ore resources, aero magnetic and ground geophysical surveys, could definitely be used as one of the tools specially to target mineralisation on regional …

The areas with iron ore deposits were expressed in the geophysical results by low resistivity, high chargeability, and moderate to high magnetic anomalies. Integrated interpretation of the obtained results revealed that the ore deposits exist in the form of lenses with variable thickness ranging from few meters to about 30-m thick.

Based on the recommendations of the Committee constituted to examine the issue of misclassification of different grades of iron ore and other minerals, in October 2023 the Ministry of Mines, vide letter dated 03.10.2023, issued guidelines to minerals rich State Governments for prevention of misclassification of different grades of iron ore and ...

This article investigates the potential of using MagArrow, a drone-based magnetometer, in conjunction with Ground Penetrating Radar (GPR) for mineral prospecting and exploration. The geophysical ...

With a total resource of 22,487 million tonnes of haematite (Fe2O3) and 10,789 million tonnes of magnetite (Fe3O4), India ranks seventh among the countries to possess abundant iron ore resources, in the world. India is not only one of the leading producers of iron ore but also at present second largest manufacturer of steel in the …

The geophysical mapping employing ground grav-ity and magnetic survey in the Geological Survey of India, northeastern region has been started since

The USGS Airborne Geophysics for Rare Earth Element Deposits (AGREED) project coordinated with industry to use high resolution airborne geophysical data collected over some of the advanced rare earth element (REE) projects in the U.S. These data were analyzed, interpreted and modeled to generate an improved …

7.1.1 Introduction. Geophysical surveys occupy an important position in the entire gamut of mineral exploration with a well-defined objective in all stages of exploration, thus the role of geophysical surveys is multidimensional. Geophysical surveys are essentially source-response geological studies; source being the natural fields of the earth ...
