| 1 | Tourmaline from the Archean G.R.Halli gold deposit,Chitradurga greenstone belt,Dharwar craton(India):Implications for the gold metallogeny显示文摘Tourmaline occurs as a minor but important mineral in the alteration zone of the Archean orogenic gold deposit of Guddadarangavanahalli(G.R.Halli) in the Chitradurga greenstone belt of the western Dharwar craton,southern India.It occurs in the distal alteration halo of the G.R.Halli gold deposit as(a) clusters of very fine grained aggregates which form a minor constituent in the matrix of the altered metabasalt(AMB tourmaline) and(b) in quartz-carbonate veins(vein tourmaline).The vein tourmaline,based upon the association of specific carbonate minerals,is further grouped as(i) albite-tourmaline-ankerite-quartz veins(vein-1 tourmaline) and(ii) albite-tourmaline-calcite-quartz veins(vein-2 tourmaline).Both the AMB tourmaline and the vein tourmalines(vein-1 and vein-2) belong to the alkali group and are classified under schorl-dravite series.Tourmalines occurring in the veins are zoned while the AMB tourmalines are unzoned.Mineral chemistry and discrimination diagrams reveal that cores and rims of the vein tourmalines are distinctly different.Core composition of the vein tourmalines is similar to the composition of the AMB tourmaline.The formation of the AMB tourmaline and cores of the vein tourmalines are proposed to be related to the regional D1 deformational event associated with the emplacement of the adjoining ca.2.61 Ga Chitradurga granite whilst rims of the vein tourmalines vis-à-vis gold mineralization is spatially linked to the juvenile magmatic accretion(2.56-2.50 Ga) east of the studied area in the western part of the eastern Dharwar craton. | Susmita Gupta M.Jayananda Fareeduddin | 2014 | Geoscience Frontiers2014，5，6： | 5 |

| 16 | Zooplankton community of Keibul Lamjao National Park (KLNP) Manipur, India in relation to the physico-chemical variables of the water显示文摘Keibul Lamjao National Park(KLNP), a floating park in Loktak Lake, Manipur(India) was studied from Winter(WIN) to Post Monsoon(POM) for its zooplankton composition and some selected water parameters. The resultant data were subjected to multivariate techniques ? Principal Component Analysis(PCA) and Canonical Correspondence Analysis(CCA). Analyses of water parameters with PCA revealed that the first PC axis(PC1) accounts for maximum variance in the seasonal data, explaining a variability of 91%. The PCA revealed that the seasonal variability in water parameters was due to the wet and dry cycle of seasons and the stations were distinguished on the basis of transparency and turbidity. Zooplankton abundance was dominated by copepods followed by cladocerans. Temporally, abundance of copepods reached a maximum during Post-monsoon(POM)(3 880 ind./L). Spatially, S6 was found to be most abundant of the other stations in zooplankton. Copepodites and nauplii larvae were the major components of zooplankton. The Rotifera were the least abundant among the three zooplankton groups. Brachionus formed the major component of Rotifera zooplankton at all the stations during the study period. In the Cladocera, Macrothrix was present during all the four seasons, while Pleuroxus, Oxyurella, Kurzia and, Diaphanosoma were rare. The CCA shows that maximal temporal variability in zooplankton abundance was explained by temperature and rainfall. ANOVA revealed no significant difference in mean zooplankton abundance among the seasons, but there was a statistically significant difference among the sites. | Aribam Satishchandra SHARMA Susmita GUPTA N Rajmuhon SINGH | 2017 | Chinese Journal of Oceanology and Limnology2017，35，3： | 0 |

| 18 | Photo-catalytic decolourisation of toxic dye with N-doped titania:A case study with Acid Blue 25显示文摘Dyes are one of the hazardous water pollutants.Toxic Acid Blue 25,an anthraquinonic dye,has been decolourised by photo-catalysing it with nitrogen doped titania in aqueous medium.The photo catalyst was prepared from 15% TiCl 3 and 25% aqueous NH 3 solution as precursor.XRD and TEM revealed the formation of well crystalline anatase phase having particle size in the nano-range.BET surface area of the sample was higher than that of pure anatase TiO 2.DRS showed higher absorption of radiation in visible range compared to pure anatase TiO 2.XPS revealed the presence of nitrogen in N-Ti-O environment.The experimental parameters,namely,photocatalyst dose,initial dye concentration as well as solution pH influence the decolourisation process.At pH 3.0,the N-TiO 2 could decolourise almost 100% Acid Blue 25 within one hour.The influence of N-TiO 2 dose,initial concentration of Acid Blue 25 and solution pH on adsorption-desorption equilibrium is also studied.The adsorption process follows Lagergren first order kinetics while the modified Langmuir-Hinselwood model is suitably fitted for photocatalytic decolourisation of Acid Blue 25. | Dhruba Chakrabortty Susmita Sen Gupta | 2013 | Journal of Environmental Sciences2013，25，5： | 0 |
