     Petrogeochemical diagrams are effective and common tools in current pertrogeochemical research, used for rock classification,genetic discrimination of rocks and ore deposits,tectonic environment discrimina-tion,and evaluation of the geological evolutionary history.This paper examines the analysis support softwares for petrogeochemical diagrams and identifies the key issues related to the softwares.These issues include the limitations of available diagram types and quantity,the lack of automation,the weakness of software independ-ence,and so on.By collecting 232 diagrams,which show 8 different categories of petrogeochemical fields,we used the postfix expression to calculate and plot diagrams of these fields automatically and used XML to define and extend the diagrams.A program based on expertsworkflow in the field of petrogeochemistry is designed, which can be used to draw,plot,and compute petrogeochemical diagrams,and also can be used in common methods of calculation,such as CIPW.
