The authors carried out interaction experiment of acid fluid with plagioclase under different temperatures��through the analysis of ultraviolet spectrophotometer and scanning electron microscope�� The experiment showed that ��At low temperatures plagioclase is stable�� which is marked by the ascendancy of dissolution; while at high temperatures��plagioclase is unstable��which gives priority to with corrosion��dissolution�� As the reaction temperatures rise��the mass losses increase�� ��Plagioclase formed belt solution pores along cleavages��the surface came into being intragranular dissolved pores�� ��At 160�� and 190�棬the secondary kaolinite precipitation formed��as temperatures rise kaolinite crystalline form becomes good�� experimental reaction intensity increases�� �� With the reaction temperature rise��the concentrations of K⁺ ��SiO₂ and salinity increase��
