Thirteen samples of the primorogenic Haparanda suite in Norrbotten, northern Sweden, are analysed for major elements and the trace elements Rb, Sr, Ba, Cu, Zn, Mo, Sn, Be, Nb, Y, Zr, Cr, Ni, V, F, Cl and S. The results accord with the view that the Haparanda suite is an I-type rock suite generated in a compressional environment. The Sn-content is higher than expected but Sn, Mo and Be are not enriched in the most silicic samples. The F-content is highest in gabbros and Mo is correlated with Cu.
