Paleomagnetism (18 sites, 231 specimens) of Lower Carboniferous carbonates in Northern Ireland reveals three characteristic remanent magnetization (ChRM) components. Six sites from Brigantian limestones have a Middle Triassic (239 ± 7 Ma) secondary chemical remanent magnetization (CRM) in hematite,...
