Greenstone Metamorphism, Hydrothermal Alteration, and Gold Mineralization in the Genetic Context of the Granodiorite-Hosted Gold Deposit at Jonnagiri, Eastern Dharwar Craton, India*
Gold. India is one of the world's largest consumers of gold, with almost 80 per cent of demand coming from end-use in jewellery and as investments. India has the world's largest private gold holdings; consumer preferences for gold are culturally entrenched and unlikely to change meaningfully out to 2035.

American Mineralogist, 2021. This study presents a petrogeochemical and boron isotope study on tourmaline from the barren Damai, and the contemporaneous but ore-bearing Dewulu and Meiwu intrusions, to better understand the origins, sources, and fluid evolution of magmatic-hydrothermal ore systems and provide ore formation implications for gold, copper, and iron deposits in the …
However, there is a lack of understanding regarding the genesis of gold mineralization in the Pahrdiha-Rungickocha deposit, which has been addressed in this study. A unique feature associated with the gold mineralization here is the presence of coeveal chromite-cored magentite, which occurs as euhedral rims on relict chromite cores.
In India, gold mineralisation is found in the Archaean greenstone/schist belts, granitoids adjacent to greenstone belt, Proterozoic Fold Belts and in the Southern Granulite Terrain.
Gold Mines in India have a rich historical legacy, with notable sites like Kolar Gold Fields in Karnataka and Hutti Gold Mines shaping the country's mining heritage. While Kolar is now inactive, Hutti continues to contribute significantly to domestic gold production. These mines highlight India's ancient expertise in metallurgy and play a key role in reducing gold imports, …
The gold content in the placer gold mine is extremely low, and it is known as the gold panning by beneficiate the placer gold through various energy-efficient placer gold equipment. Among various gold extraction methods, the gravity separator method is energy-saving, efficient, environmentally friendly, and is suitable for placer gold ore process.
Explore the production of gold in India, examining the impact of gold mining and how this shapes the nation's economic landscape with the World Gold Council.
Gold mineralization in Southern Granulite Terrain (SGT) of India has close spatial relationship with the shear zones (Moyar-Bhavani) present in Cauvery Suture Zone.
In India, gold mineralization of economic importance is mainly restricted to Archean greenstone terranes of the Dharwar Craton (DC). The eastern block of the DC has a high favorability for hosting major gold deposits such as Kolar, Hutti, and Ramagiri, whereas the western block hosts only a few smaller deposits such as Gadag, Ajjahanahalli, and …

In situ U-Pb dating of monazite and xenotime in gold reefs of the Gadag (2,522 +/- 6 Ma) and Ajjanahalli (2,520 +/- 9 Ma) gold deposits reveal a previously undated episode of gold mineralization at 2.52 Ga, substantially younger than the 2.55 Ga Hutti deposit in the eastern Dharwar Craton.
The Tien Shan mountain range extends for more than 2500 km from the Kyzylkum desert of Uzbekistan, through Tajikistan and Kyrgyzstan, and continuing into the Gobi desert of western China (Fig. 1).This linear, continuous orogenic belt hosts at least 13 deposits hosting >100 t of gold, including the ∼6000 t Muruntau gold, deposit that together comprise the largest …

The World Class Hutti Gold Mine is considered as one of the prestigious stable underground ancient metal mines in India and is an "Industrial Oasis in the desert" in the Hutti-Maski schist belt. The Hutti Gold Mines has so far produced 93.33 tonnes of gold metal (as on March, 2020) from 17.58 million tons of ore at an average grade of 5.30 g/t.
Mineral prospecting and exploration is important to identify and locate new mineral resources as it improves the socio-economic scenario of a nation. The present study is an attempt to delineate and evaluate concealed mineral deposits in central India. Electrical and electromagnetic methods are generally employed for prospecting
