Abstract:

The usual solution that distribute albite over alkali feldspar and plagioclase is Rietmann phase diagrams, which need a large quantity of  calculations whose process are complex with man-made factors. Programming simulation with human thinking and work steps to achieve the Rietmann phase diagrams, including phase diagram of digital, phase diagram partition, solving the sample points in miscibility region, solving the sample points of the immiscibility region and solving the end result, etc., were discussed. Also, key code of the programming simulation with Matlab language were given. Some examples showed that the calculation by hand takes about 50 min, however ,the method needs 2-3 s with accuracy of 100%.

Key words: Rietmann, phase diagrams, albite, distribution, petrochemistry
