Experimental conditions were set as: vapor pressures, 100°∼ 200℃, solution concentrations of 0.1 ∼ 1M, and 1 ~ 60 days. Experimental results are as follows. Firstly, Na-rich plagioclases are easy to transform to analcime, p-zeolite and chabazite, but they are ready to transform to mordenite when sufficient amount of silica can be supplied from the plagioclase-bearing rocks during their alteration in marine or salt lake environment. This is agreed with field observations. Secondly, thomsonite and garronite, and p-zeolite, gismondine and gobbinsite are easy to be synthesized from Ca-rich plagioclases in marine and salt lake environments, respectively, harmotome is favored to form when sufficient amount of silica can be supplied from alteration of Ca-rich plagioclase-bearing rocks in marine and salt lake environmentsapplication/pdf18367 bytesapplication/pdfzh-TW國立臺灣大學地質科學系暨研究所斜長石方沸石p-沸石菱沸石桿沸石絲光沸石交沸石plagioclaseanalcimep-zeolitechabazitethomsonitemordeniteharmotome[SDGs]SDG14reporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/11767/1/892116M002043.pdf
