As a result, the author discusses the thermodynamics habitus for the minerals either. With the calculation of the thermodynamics modeling, we run the dissolutionmodeling experiments for primary minerals (potash feldspar, albite, anorthite, andpyroxene, hornblende), which is under the conditions of organic acidic and 20 varietytemperature and pressure. The dissolution modeling experiments include 4 anorthitedissolution experiments, 8 pyroxene dissolution experiments, 8 hornblendedissolution experiments. We catch the records on the X ray diffraction, chemistryanalysis, SEMphotos, and the PH parameters. By theway, we discuss the dissolution habitus for the minerals either.
