摘要
钠长石是我省的一个新发现矿种。钠长石产于石英闪长岩体的外接触带九里坪组的流纹质晶屑玻屑凝灰岩层位中 ,矿体呈似层状产出。其成矿主要受侵入体、地层层位及构造控制。矿床成因类型属岩浆期后热液交代蚀变型层控矿床 。
Albite is a new mineral to Zhejiang province,which was just discovered recently.The bedded albite ores occur in the rhyolitic crystal-vitric tuff of Jiuliping Formation,which is located in the exocontacts of quartz diorite bodies.Its mineralization was mainly comtrolled by the intrusives,Stratigraphic beds and structures.The genesis belongs to postmagmatic hydrothermal metasomatic alteratim type,and the minerali zation time belongs to late Yanshanian period.
