| Abstract: | 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 and physical properties are not different from normal metamict allanite,but there is an obvious difference in their behaviour of iron crystallochemistry.The mineral in this study was thermally decomposed and became a mixture of complicated oxides at temperature above 930℃. |
