摘　　要：综合应用显微观测、化学分析和物化检测手段,对黑龙江省穆棱沸石矿床沸石岩进行了系统研究,确定其矿物组成主要为斜发沸石和丝光沸石,二者可单独产出,也可形成混合型矿石。该矿石在成分上属高硅型沸石,SiO2 Al2O3比值均大于8,有害元素As、Pb等较低。物化性能测试表明,穆棱沸石矿为高品级沸石矿,矿石平均热失重值达12.8%,NH+4交换容量为146.10meq 100g,K+交换容量平均9.58mmol 100g,丝光沸石热稳定性可稳定至800℃～900℃,具有良好的开发应用前景。This paper studies the characteristics and physio-chemical properties of Muling zeolite deposit in Heilongjiang province, northeast China. Mordenite and clinoptilolite are the main zeolite minerals in the deposits. The minerals are chemically rich in silica, with relatively high SiO2/Al2O3 ratio more than 8. Zoelite ores are of very high quality with good physio-chemical properties. The average thermo-gravimetric lost is 12.8%, the mean NH+4 exchange is up to 146.10meq/100g and K+exchange is up to 9.58mmol/100g, the mordenite can keep structue stable when heated to 800℃～ 900℃.
