Interpretations of Rb–Sr and Sm–Nd data from the Grunehogna Granite demonstrate that anatexis of and mixing with Høgfonna Formation sedimentary rocks, caused by hot basic sills of ~1100 Ma Borgmassivet Suite, are consistent, with the granite εNdεSr100Ma data, partially overlapping Borgmassivet Suite...
