- Major, trace element and Sr-Nd isotope data on complex clinopyroxenes in the oldest lavas, the B1 basalts, in the Oslo Rift, SE Norway. The clinopyroxenes have a homogeneous core of resorbed Cr-diopside originating in the SCLM. The Cr-diopside is coated by less Cr-rich concentrally zoned diopside formed partly by reaction between Cr-diopside and basaltic magma, followed by crystallization from mafic magma undergoing fractional crystallization, magma mixing and assimilation of crustal melts. Outwards the diopside turns into concentrically zoned augite formed from the host magma.
