  1. Data sources: densities are from Emslie and Ermanovics (1975), Feininger and Goodacre (1995), Kearey (1978), Paradis (2004). Radiogenic element concentration data are from 163 samples from the SIGÉOM (2018) database. Thermal conductivity data are from Mareschal (2018), Jessop et al. (2005). Average values are in parenthesis. Number of samples for radiogenic element concentration is given in parenthesis after rock type
