By means of XRD,IR,DTA,SEM and microprobe analysis,the authors investigated the mineralogical characteristics and origin of mordenite in bubble spheres of rhyolite and in zeolite ores of tuff lava and pyroclastic tuff from Jinyun County,Zhejiang Province.The investigation shows that there are significant differences in mineralogical characteristics of mordenite from bubble spheres and orebodies in many aspects.In mineral paragenesis,the former is only associated with quartz,while the latter with not only quartz,but also clinoptilolite and montmorillonite in general.In crystal parameters,the former shrinks the 12-unit rings while the latter shrinks the 8-unit rings.In chemical formulae,the former gets higher ratios of K_2O/CaO、SiO_2/Al_2O_3and K_2O/Na_2O while the latter gets higher positive charge surplus.Considering the differences in mineralogical characteristics and occurrences,the authors suggest mordenite in the bubble spheres is the product of crystallization from volcanic hydrothermal fluid trapped by bubbles while that in the orebodies is the replacement product of low-temperature interstitial solution during the petrogenesis of ore-hosting volcanic rocks.

运用X射线衍射、红外吸收光谱、差热-热重分析、扫描电镜形貌研究及微区化学成分分析等手段,研究了浙江省缙云县产于球泡流纹岩球泡腔体内和产于角砾凝灰岩、凝灰熔岩型沸石矿体内的丝光沸石的矿物学特征及其成因机制。研究表明,球泡腔体内的丝光沸石与矿体内丝光沸石的矿物学特征存在明显差别:前者仅与石英紧密共生,而后者则与斜发沸石、石英以及蒙脱石等紧密共生;前者12元环通道半径收缩,而后者则8元环通道半径收缩。同时,前者具有更高的K2O/CaO、SiO2/Al2O3以及K2O/Na2O比值,而后者则阳离子电价过剩程度更高。研究认为,球泡内丝光沸石是球泡捕获的火山热液结晶产物,而矿体内丝光沸石是火山岩成岩期间隙溶液活动产物。
