Normal isochron (a) and inverse isochron (b) plots constructed from all step-heating data with representative ages and errors shown for sample CB-KVS (Garledinne lamproite). Normal isochron (c) and inverse isochron (d) plots constructed heat-step data 6–13 with representative ages and errors shown for sample CB-KVS (Garledinne lamproite).
