From source to crust: Tracing magmatic evolution in a kimberlite and a melilitite using microsample geochemistry

We present an integrated microsampling trace element and isotopic study of primary minerals within the Jos kimberlite, Canada, in order to observe how different phases record progressive crustal interaction in the evolving kimberlite. Identification of the least contaminated phases provides the best...
