通过紫外分光光度计分析和扫描电镜观察，开展不同温度下酸性流体与斜长石相互作用实验得出：①在低温条件下斜长石较稳定，以溶解为主；在高温条件下，斜长石不稳定，以溶蚀、溶解为主；随反应温度升高，质量损失增大。②斜长石沿解理形成条带状溶孔，沿表面形成粒内溶孔。③在160℃和190℃条件下，形成新生高岭石沉淀，温度升高高岭石晶形变好，实验反应强度增大。④随反应温度升高， K＋、 SiO2和矿化度浓度升高。

The authors carried out interaction experiment of acid fluid with plagioclase under different temper -atures, through the analysis of ultraviolet spectrophotometer and scanning electron microscope .The experiment showed that①At 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 tem-peratures rise , the mass losses increase .②Plagioclase formed belt solution pores along cleavages , the surface came into being intragranular dissolved pores .③At 160℃ and 190℃, the secondary kaolinite precipitation formed , as temperatures rise kaolinite crystalline form becomes good , experimental reaction intensity increases .④With the re-action temperature rise , the concentrations of K +, SiO2 and salinity increase .
