PETROLOG 3.1.1.3 (August 19, 2012)

Release Notes to Petrolog 3.1.1.3:

Modified calculations of trace element concentrations in minerals. The effective Kd values are now independent from the total trace element content in the mineral, and are exactly the same as is set in the interface.

An minor error in calculating Ni content in olivine when using the olivine-melt models of Beattie, 1993 and Beattie 91 is corrected.

Output values for oxygen fugacity (lgfO2) were incorrect in calculations with melt-mineral models of Ariskin & Barmina, 1999 for Ilmenite and Ariskin & Barmina, 1999 for magnetite. This did not affect the dNNO values and the calculations of mineral and melt compositions and temperatures. This is now fixed.

Calculation of H2O content in minerals by setting Kd values for each mineral is now enabled. Calculations are identical to those for trace elements and are described in the Manual.
