The simultaneous partitioning of the divalent cations of Ni2+, Mg2+, Co2+, Zn2+ , Fe2+ Mn2+ and Ca2+ between talc or chlorite (clinochlore) and 2M aqueous chloride solutions was investigated experimentally in the temperature range of 500 to 700 °C, 1 kbar. The PC-IR curves both for talc and chlorite have a peak near Mg2+. Zn2+ shows a negative deviation as with other minerals with an octahedral site. Co2+ also shows a negative deviation, and the deviation seems to be related to polymerization Of SiO4 tetrahedra. On the other hand, Ni2+ shows a positive deviation, and the deviation seems to decrease with increasing temperature.
