Kranidiotis and MacLean (1987)‎ modified the Cathelineau and Nieva (1985)‎ expression by calculating a corrected AlIiv value (AlIVc ) as follows: AlIVc = AlIV+ ۰.۷(Fe/[Fe + Mg]), from which the temperature, T (in °C) is then computed according to:
T = 106 AlIVc + ۱۸
Kranidiotis and MacLean (1987)‎ argued that their function is applicable to situations where chlorite grows in an "Al-saturated environment," i.e.‎, in the presence of other aluminous minerals.‎

Cathelineau (1988)‎ suggested that equation of T (˚C) = -61.‎92 + 321.‎98 AlIV has the potential to be used as a chlorite geothermometer of general applicability in diagenetic, hydrothermal, and metamorphic settings because the value of AlIV appears to be independent of rock Lithology.‎

Jowett (1991)‎ suggested a similar type of correction, derived from an isothermal Fe/(Fe + Mg) normalization compositions:
AlIVc = AlIV+ ۰.۱ (Fe/‎ ‪(Fe + Mg)‬)
T (°C) = 319 AlIVc - ۶۹
Jowett (1991)‎ claimed that this Fe-Mg-modified geothermometer is applicable to a variety of systems in
the range 150~ to 325~ for chlorites with Fe/(Fe +Mg) values < 0.‎6.‎
