Location of LIP centres of the past 300 Myr (today and at eruption time). OP
continental LIP (at least
nine erupted in existing rifts listed in the last column). LIPs are reconstructed according to a hybrid reference frame (moving hotspot frame
back to 120 Ma and a TPW-corrected palaeomagnetic frame before that time; Doubrovine

.,
2012
; Torsvik
