1.80–1.75 Ga granite suites in the west Troms Basement Complex, northern Norway: Palaeoproterozoic magma emplacement during advancing accretionary orogeny, from field observations

•1.80–1.75 Ga TIB-1 granite emplacement during late-Svecofennian orogeny.•Sills injected into TTG gneisses leaving mafic pendant layers between granite sills.•Melt pathways along TTG foliation, thrusts, fold axial surfaces, and strike-slip faults.•Back-arc extension in advancing accretionary orogenic emplacement model.
