  • The number of droplets measured is Embedded Image. The equilibration time gives the time for which the charge was held at the final temperature after having been cooled from a starting temperature of 1100°C at 1°C/hr. Charges SI-5, SI-8 and SI-13 have a bulk composition identical to that of a dyke cutting the Sept Iles intrusion and charges M-5, M-6 and M-9 have a bulk composition typical of an intermediate basalt from the Mull Tertiary volcano (for further details see Charlier and Grove (2012)).
