<p>New geochemical data for mafic intrusions within the Eocene Nisai Formation along the suture zone between the Indian and Eurasian
plates are used to constrain their petrogenesis and assess the local tectonics and mantle dynamics. Petrological and geochemical
data indicate that these alkalic intrusions have moderately enriched incompatible trace element compositions similar to ocean
island basalt magmatism. Modelling suggests that these intrusions are the result of 1–5% melting of a deep, enriched, predominantly
garnet lherzolite, with a small amount of subduction-derived fluids. These melts then underwent fractional crystallization
at lithospheric depths of <em>c</em>. 30 km.
