摘　　要：新疆富钕褐帘石的首次发现及矿物学特征丁奎首，张培善，李哲（中国科学院地质研究所北京１０００２９）关键词富钕褐帘石，穆斯堡尔谱，变生作用１产状与一般特征普通褐帘石多含铈，常呈副矿物存在于花岗岩、矽卡岩、火山灰（Ｉ。ｅｔｔ，１９８！）、变质泥岩（Ｓａｋａ...The crystal clusters of Nd-rich allanite were first found in Xinjiang by the authors. The mineral is rich in neodymium and without ferric iron.Its structure andphysical properties are not different from normal metamict allanite,but there is anobvious difference in their behaviour of iron crystallochemistry.The mineral in thisstudy was thermally decomposed and became a mixture of complicated oxides at temperature above 930℃.
