“…Algoma-type BIF occurred in the KolareRamagirieHuttieMaski greenstone belts in the Dharwar Craton, which also contains a large number of greenstone belt type Au deposits (e.g., Karnataka; Kolar) and graphite schists (Kolb et al, 2004;Turchenko et al, 2009;Shi et al, 2010).

“…The VMS metamorphosed Pb-Zn-Cu deposits (e.g., Mamandur), the Ni-Co-Cr (e.g., Hulk Hill) deposits related to ultramafic rocks and the Vairamangalam deposit of muscovite pegmatites occurred in the lower Archaean supracrustal sequences, which metamorphosed under granulite-facies conditions and were incorporated into granite gneisses 3.1 Ga in age. In the Nuggihalli and Holenarasipur structures, which commonly occur at the bottom of green-stone belts, these metasedimentary rocks overlap a layered Cr, Fe, and Ti-bearing peridotiteegabbroeanorthosite complex, as well as the relics of komatiites (e.g., Hussain and Naqvi, 1983;Turchenko et al, 2009;Shi et al, 2010).…”

“…In the early and middle Archaean, the Indian continental nuclei was formed (Sharma, 2009). The rapid growth of the continental crust led to the extensive formation of gneiss, charnockite, and migmatite, as well as to the accumulation of abundant mineral resources (Goodwin, 1996;Sharma, 2009;Turchenko et al, 2009). Vast reserves of Algoma-type BIF (e.g., Churuppa) occur in the gneiss belts and granuliteegneiss domain in the southern Dharwar Craton, which are closely related to volcano-sedimentary rocks.…”

“…In the mid and late NeoArchaean, the continental crust significantly grew and micro-continental blocks were amalgamated, accompanied by large-scale development of greenstone belts and apparent metallogenic processes (Zhao et al, 2003a;Artemieva, 2006;Sharma, 2009;Turchenko et al, 2009). Algoma-type BIF occurred in the KolareRamagirieHuttieMaski greenstone belts in the Dharwar Craton, which also contains a large number of greenstone belt type Au deposits (e.g., Karnataka; Kolar) and graphite schists (Kolb et al, 2004;Turchenko et al, 2009;Shi et al, 2010).…”

“…The NCC and the IND experienced a complex geological evolution since the early Precambrian, characterized by abundant Precambrian solid mineral resources and variable metallogenic mechanisms (Turchenko et al, 2009;Zhai, 2011). We establish a mineralization characteristic database of the NCC and the IND on a scale of 1:50,000,000.…”

a b s t r a c tThe correlation between the North China Craton (NCC) and the Indian Shield (IND) has been a hot topic in recent years. On the basis of ore deposit databases, the NCC and IND have shown broad similarity in metallogenesis from the middle Archaean to the Mesoproterozoic. The two blocks both have three major metallogenic systems: (1) the Archaean BIF metallogenic system; (2) the Paleoproterozoic Cu-Pb-Zn metallogenic system; and (3) the Mesoproterozoic Fe-Pb-Zn system. In the north margin of the NCC and the west margin of the IND, the Archaean BIF-Au-Cu-Pb-Zn deposits had the same petrogenesis and host rocks, the Paleoproterozoic Cu-Pb-Zn deposits were controlled by active belts, and the Mesoproterozoic Fe-Pb-Zn deposits were mainly related to multi-stage rifting. Matching regional mineralization patterns and geological features has established the continental assembly referred to as "NCWI", an acronym for the north margin of the NCC (NC) and the west margin of the IND (WI) during the middle Archaean to the Mesoproterozoic. In this assembly, the available geological and metallogenic data from the Eastern Block and active belts of NC fit those from the Dharwar craton and the AravallieDelhi eVindhyan belt of WI, respectively. Moreover, the depositional model and environment of Paleoproterozoic metasedimentary manganese deposits in NCWI implied that the assembly may be located at low latitudes, where the conditions were favorable for dissolving ice and precipitating manganese deposits.Ó 2015, China University of Geosciences (Beijing) and Peking University.

Delineation of extension of uranium mineralization zone using resistivity and Very Low Frequency electromagnetic surveys around South Purulia Shear Zone, India

During a random radiometric survey, nuclear radiation was detected near exposed rocks in an open-pit phosphatemine at Beldih (Purulia, W.B.), India. Radiometric analysis of rock samples reveals a significant concentration of uranium. Geological study suggests that Beldih phosphate mine lies near the South Purulia Shear Zone (SPSZ). Shear zones in the region are E-W striking elongated zone and associated with uranium mineralization (famous Singhbhum shear zone for several uranium mines). Electrical resistivity (profiling and sounding) and Very Low Frequency (VLF) electromagnetic surveys were performed around Beldih mine to delineate the suitable conducting zones which may be associated with uranium mineralization. Significant lateral extension of possible source is delineated; it could be exploited later on a large scale for commercial utilization. It is observed that gradient resistivity profiling (GRP) survey is the most suitable technique to explore the nearly vertical conducting structure. The GRP measurements were carried out at different locations. A good correlation of low resistive zones on various GRP was observed from the measured data. The study concludes that subsurface structures are nearly vertical and have alternate resistive and conducting bands. An inclined bore-hole drilled confirms the presence of alternate resistive and conducting structures and uranium mineralization is detected in conducting bands. This suggests that GRP can be conducted for precise location of the target zone. This will help in planning bore holes for drilling to find the exact thickness, lateral and vertical extent of the deposit for commercial utilization. VLF measurements were also carried out along various profiles. Even though VLF observation was quite noisy due to presence of power lines in the area; this method can be used to map the area and model the data for actual sub-surface conducting zones in less noisy areas as a support for drilling works.
