The Paleoproterozoic Näränkävaara intrusion, northern Finland, has a surface area of 25 km × 5 km and a stratigraphic thickness of about 3 km. Based on previous and new whole-rock and mineral chemical data as well as new Sm-Nd and U-Pb isotope geochemical data, the stratigraphy, petrogenesis, and or...
