摘要
报道了赋存于上侏罗系蚀变凝灰岩型地开石矿床中的磷铝锶石矿物。它的含量不到３％。通过氢氟酸溶蚀，富集了磷铝锶石。用ＸＲＤ和ＩＲ研究了磷铝锶石的矿物学特征，并获得了良好ＩＲ图谱。磷铝锶石矿物具有特征的３４７５ｃｍ－１和３０７０ｃｍ－１ＯＨ吸收峰可区别于其他同族矿物。这种磷铝锶石形成于成岩作用后期，晚于地开石。
Goyazite was identified in dickite dePosits of altered Jurrasic tuff Zhuji,Zhejiang Province.It makes uP as small amount as 3% of the rock and has to be studied after enriched by HF attack .Goyazitie is final confirmed by both XRFchemical composition and XRD as well as IR sPectra.A good IR sPectrum with sharP and strong absorPtion bands of goy azite was obtained,which is characterized by OH strech vibrations in 3475-1 and 3070-1.On the basis of its occurrence assis during the alteration of the tuff,and before much comPaction of the dickite claystone.
