ac Representative Thellier–Coe NRM lost versus pTRM gained (Arai) plots for the different studied flows. Neáltica lava (a), Lorenzo Pumice flow (b) and summit of Lorenzo Pumice (c). Filled circles correspond to data points obtained at each double heating step used for the best fit regression line. Open circles correspond to data points not considered for the best fit calculation. Inset shows the NRM lost (pTRM gain) versus temperature at each step. Triangles represent the pTRM checks
