An apatite-based thermodynamic model for calculations of:

(1) activities of F, Cl, OH in apatite 

(2) exchange coefficients (KDs) for OH-Cl, OH-F, Cl-F between apatite and melt

(3) water concentration in melt

We have developed a Petrological Workspace and Database tool (https://petro.wovodat.org) that allows researchers to access, share, store, and manage petrological, mineralogical, and whole rock data in a contextualised manner. 

​

Main features of PWD:​

(1) storage and management of spatial‐referenced data (from fieldwork notes to geochemical analysis) 

(2) visualisation of the hierarchical relationship between different types of data using the Workspace tool

(3) graph plots on petrological data 

(4) data sharing in a database structure that can be managed by different authorisation levels.
