Major and trace (including rare earth)element abundances, mineral compositions and Nd and Sr isotopic compositions have been determined for the mafic dykes (classified as basanite) and gabbro of the northern Island belt of Kutch rift basin. These are petrographically and geochemically distinct but have similar mantle normalized trace element patterns Measured87Sr/86Sr ratios in the mafic dykes vary from 0 70428 to 0 70593 &Nd(i) varies from 0 27 to - 6 5. The isotopic compositions are broadly similar to that of Mahabaleshwar flows of western Deccan volcanic province. The geochemical character suggests the influence of fractional crystallisation in the evolution of the basanite dykes. The parent magma was enriched in K, Ti, Na and P suggesting derivations from an enriched source during the early phase of lifting Palaeomagnetic data on the dykes show the presence of both normal polarity direction at Dm = 338°, Im=-47° and reverse polarity direction at Dm=14l° and Im=34° indicating multiple intrusion Virtual Geomagnetic Pole(VGP) for the basanite dykes differs from Deccan Super pole suggesting a magmatic event older than the main Deccan eruption.Keywords

Basalts occur as sub-alkaline tholeiites in the Naga ophiolite belt. They bear an E-MORB affinity ascribed to aqueous fluid addition from a dehydrating oceanic crust in a supra-subduction zone during the Indo-Burma plate collision. They are commonly altered to spilite. They exhibit relatively poor REE fractionation with almost flat chondrite-normalized patterns. Eu-anomalies are not prominent, indicating the negligible role of plagioclase fractionation in their petrogenesis. Rock magnetic studies suggest that magnetite is the major magnetic mineral in these Upper Cretaceous basalts.Keywords

Teaching Learning process involves different activities. Every lecture has an outcome. However, if the lecture is forenoon, there is a need to energize the students with learning outcomes. Role-play and round quiz are energetic learning activities. Role-play activity increase numerous abilities in the students such as team building, leadership quality, demonstration, thinking, working, playing, creativity, etc. Round quiz is a game applied for the fuzzy logic course. Round quiz clears the tiniest of their doubts and prods them to answer it themselves. Students become energetic for these activities. The paper demonstrates learning with joy.Keywords
