Mineralogy and geochemistry of trachytic rocks from the Lichi Volcanics, Eastern Himalaya: insights into the Kerguelen mantle plume activity in the Eastern Himalayan Region

Acta Geochimica 2024年第1期43卷 180-197页

作者： Pallabi Basumatary Deepshikha Borah Hiredya Chauhan Tribujjal prakash Bibhuti Gogoi Department of Geology Cotton UniversityGuwahatiAssam 781001India Wadia Institute of Himalayan Geology DehradunUttarakhand 248001India

The Lichi volcanics are a suite of mafic-intermediate-felsic rocks and are considered coeval with the Abor volcanics(~132 Ma) of the Siang window in the Eastern Himalaya. Here, we present the first report of trachytic rocks from the Lichi volcanics, which are exposed in the Ranga valley, along the Kimin-Yazali road section in the Eastern Himalayan Region, Northeast India. The trachytes occur in close association with sandstones of the Gondwana Group of rocks and are characterised based on field, petrographical, and geochemical *** fine-grained trachytes are composed of alkali feldspar, biotite, plagioclase, sodic-amphibole, apatite, illmenite, and titanite. The REE profiles of the evolved trachytic rocks(higher SiO_(2)content) display fractionated trends. The fractionation of accessory mineral phases, like apatite and titanite, was possibly responsible for the strongly fractionated REE patterns of the evolved *** trachytic rocks demonstrate high apatite saturation temperatures of 988 ± 14 ℃(1σ, n = 8). The Aluminium Saturation Index(< 1.1) and binary discrimination diagrams of these peralkaline trachytes define their affinity with A-type granitoids. Elemental ratios like Y/Nb, Nb/U,and Ce/Pb signify that the Lichi trachytes are differentiated products of mantle-derived ocean island basalts. Trace elemental discrimination diagrams Th/Yb versus Nb/Yb, Y versus Nb, and Y + Nb versus Rb reflect a within-plate tectonic regime for the trachytes. From the results presented in this work, we infer that the development of rifting events during the breakup of eastern Gondwana due to the onset of Kerguelen plume activity further led to underplating of basic magma in lower crustal levels. These parental basaltic magmas underwent fractionation processes forming differentiated trachyandesites and *** into consideration the similarities recorded between the Lichi volcanics and Abor volcanics, this study supports the idea that Kerguelen plume ac

Techno-economic and environmental impact analysis of electric two-wheeler batteries in India

CLEAN ENERGY 2024年第3期8卷 147-156页

作者： Gupta, Aman Bose, Ditipriya Tiwari, Sandeep Sharma, Vikrant prakash, Jai Aligarh Muslim Univ Zakir Husain Coll Engn & Technol Dept Green Energy & Sustainable Dev Aligarh 202002 Uttar Pradesh India Natl Inst Solar Energy Battery Testing Facil Gurugram Faridabad Rd Gurugram 122003 Haryana India

This paper presents a comprehensive techno-economic and environmental impact analysis of electric two-wheeler batteries in India. The technical comparison reveals that sodium-ion (Na-ion) and lithium-ion (Li-ion) batteries outperform lead-acid batteries in various parameters, with Na-ion and Li-ion batteries exhibiting higher energy densities, higher power densities, longer cycle lives, faster charge rates, better compactness, lighter weight and lower self-discharge rates. In economic comparison, Na-ion batteries were found to be similar to 12-14% more expensive than Li-ion batteries. However, the longer lifespans and higher energy densities of Na-ion and Li-ion batteries can offset their higher costs through improved performance and long-term savings. Lead-acid batteries have the highest environmental impact, while Li-ion batteries demonstrate better environmental performance and potential for recycling. Na-ion batteries offer promising environmental advantages with their abundance, lower cost and lower toxic and hazardous material content. Efficient recycling processes can further enhance the environmental benefits of Na-ion batteries. Overall, this research examines the potential of Na-ion batteries as a cheaper alternative to Li-ion batteries, considering India's abundant sodium resources in regions such as Rajasthan, Chhattisgarh, Jharkhand and others.
