Chemical, isotopic and amino acid composition of Mukundpura CM2.0 (CM1) chondrite: Evidence of parent body aqueous alteration
Rudraswami, N.G.; Naik, A.K.; Tripathi, R.P.; Bhandari, N.; Karapurkar, S.G.; Prasad, M.S.; Babu, E.V.S.S.K.; VijayaSarathi, U.V.R. (Elsevier, 2019)The carbonaceous chondrites are intriguing and unique in the sense that they are the only rocks that provide pristine records of the early solar nebular processes. We report here results of a detailed mineralogical, chemical, ... -
Chemistry and petrology of Fe-Ni beads from different types of cosmic spherules: Implication for precursors
Rudraswami, N.G.; ShyamPrasad, M.; Babu, E.V.S.S.K.; VijayaKumar, T. (Elsevier, 2014)Fe–Ni beads are observed to occur in all three (Stony, Glass, Iron) types of cosmic spherules collected from deep sea sediments of the Indian Ocean. Fe–Ni beads in cosmic spherules can provide insights for understanding ... -
Correlation of the oldest Toba Tuff to sediments in the central Indian Ocean Basin
Pattan, J.N.; ShyamPrasad, M.; Babu, E.V.S.S.K. (Indian Academy of Sciences, 2010)We have identified an ash layer in association with Australasian microtektites of approx. 0.77Ma old in two sediment cores which are approx. 450 km apart in the central Indian Ocean Basin (CIOB). Morphology and chemical ... -
Extending the limit of widespread dispersed Toba volcanic glass shards and identification of new in-situ volcanic events in the Central Indian Ocean Basin
Amonkar, A.; Iyer, S.D.; Babu, E.V.S.S.K.; Manju, S. (Springer, 2020)We report the widespread extent of Toba volcanic glass shards in the Central Indian Ocean Basin. Investigation of four sediment cores (7o-17oS) revealed several shard-rich horizons (SRH) that provide the first detailed ... -
Fluid-driven Hydrovolcanic Activity along Fracture Zones and near Seamounts: Evidence from Deep-sea Fe-rich Spherules, Central Indian Ocean Basin
Amonkar, A.; Iyer, S.D.; Babu, E.V.S.S.K.; Shailajha, N.; Sardar, A.A.; Manju, S. (Wiley, 2021)An insight on occurrence of Fe-rich spherules from the Central Indian Ocean Basin (CIOB) provides an understanding of their distribution at a water depth of >5,000 m. In the present study, Fe-rich spherules are identified ... -
Fractionation and fragmentation of glass cosmic spherules during atmospheric entry
Rudraswami, N.G.; ShyamPrasad, M.; Babu, E.V.S.S.K.; VijayaKumar, T.; Feng, W.; Plane, J.M.C. (Elsevier, 2012)Glass cosmic spherules are a sub-type of S-type cosmic spherules that are almost at the end phase of fractionation and volatilization during atmospheric entry. A focused investigation of 36 glass spherules out of several ... -
Major and trace element geochemistry of S-type cosmic spherules
Rudraswami, N.G.; ShyamPrasad, M.; Babu, E.V.S.S.K.; VijayaKumar, T. (The Meteoritical society, U.S., 2016)Micrometeorites that pass through the Earth's atmosphere undergo changes in their chemical compositions, thereby making it difficult to understand if they are sourced from the matrix, chondrules, or calcium–aluminum-rich ... -
Nature of suspended particles in hydrothermal plume at 3°40'N Carlsberg ridge: A comparison with deep oceanic suspended matter
Ray, D.; Babu, E.V.S.S.K.; SuryaPrakash, L. (Current Science Association, 2017)Suspended matter from hydrothermal plume at 3◦40'N Carlsberg Ridge was studied for microtexture and geochemistry. Characteristics of these plume particles were compared with deep-oceanic particulates from different ... -
Occurrence and emplacement of chromite ores in Sindhudurg district, Maharashtra, India
Iyer, S.D.; Babu, E.V.S.S.K.; Mislankar, P.G.; Gujar, A.R.; Ambre, N.V.; Loveson, V.J. (The Geological Society of China, 2010)In the present study, the occurrence and emplacement of chromite ore deposits from two abandoned mines (Kankavali (Janoli) and Wagda) in the Sindhudurg district of Maharashtra, India are presented. These ores, that occurred ... -
Ordinary chondritic micrometeorites from the Indian Ocean
ShyamPrasad, M.; Rudraswami, N.G.; Babu, E.V.S.S.K.; VijayaKumar, T. (The Meteoritical Society, 2015)Extraterrestrial particulate materials on the Earth can originate in the form of collisional debris from the asteroid belt, cometary material, or as meteoroid ablation spherules. Signatures that link them to their parent ... -
Origin of cretaceous phosphorites from the onshore of Tamil Nadu, India
Rao, V.P.; Kessarkar, P.M.; Nagendra, R.; Babu, E.V.S.S.K. (Indian Academy of Science, 2007)Cretaceous phosphorites from the onshore of Tamil Nadu have been investigated for their origin and compared with those in the offshore. Cretaceous phosphorites occur as light brown to yellowish brown or white nodules in ...
