The present study was conducted to characterize carbohydrate and protein fractions in Phalaris minor seeds (a novel feedstuff) in comparison to conventional energy sources fed to livestock. The crude protein of P. minor seeds was similar to wheat and was higher (P < 0.05) than other conventional cereal grains evaluated. P. minor seeds recorded the highest (P < 0.05) level of ether extract, total ash, lignin, neutral and acid detergent insoluble protein. P. minor seeds had lower (P < 0.05) level of total carbohydrates than conventional cereal grains. Wheat grains exhibited highest (P < 0.05) level of non-structural carbohydrates followed by maize, P. minor, pearl millet and barley. Protein fractions PB1 and PB2 in P. minor seeds were similar to maize. Total digestible nutrients in P. minor seeds were higher (P < 0.05) than pearl millet and barley. P. minor seeds could be considered as promising energy supplement for livestock as indicated by its chemical constituents.Keywords

Studies on the magmatic enclaves, pelitic xenoliths and host Jaspa granite pluton outcropped in the Lahaul area, NW Himalaya, India illustrate that the rocks have undergone garnet-grade metamorphism. The P -T pseudosection modelling shows that the metamorphic mineral assemblage is stable in the P -T range ~4.5-7.3 kbar and ~440-500°C, matching quite well with the results obtained from the conventional geothermobarometers (5.7-8.6 kbar and 409-531°C). The observed garnet-grade metamorphism in and around the Jaspa pluton is proposed to be due to localized perturbation of high-temperature isotherms in the Tethys Himalaya, as a consequence of the Cenozoic tectono-thermal event during Himalayan orogeny. Further, the Haimanta group of Tethys Himalayan rocks in the Lahaul area has been interpreted to have attained right-way-up metamorphic field gradient.Keywords

This communication presents results of mineral and whole-rock geochemistry of rarely occurred dunites in the central part of the Nagaland–Manipur Ophiolites (NMO), North East India, and discusses their genesis and tectonic evolution. These rocks are characterized by low concentration of average CaO (0.58 wt%), Al2O3 (0.42 wt%) and ΣREE (1.24 ppm), but high Mg# (0.91–0.92) and Cr# (0.61–0.73) values in chromian spinels. They exhibit a U-shaped REE pattern depleted in MREEs, which is equivalent to dunite composition, possibly part of a restite peridotite which underwent through extensive partial melting. The estimated degree of partial melting based on chromian spinel Cr# ranged from 20.04% to 20.70%. Low concentration of TiO2 (0.10–0.16 wt%) in chromian spinel in these dunites confirms no evidence of metasomatism. Therefore, we propose that dunites in the NMO represent the remnants of residual mantle wedge which underwent extensive partial melting in a subduction zone. Absence of metasomatism indicates no melt–wall rock interaction during the process of mantle melting and final obduction on the surface.Keywords
