摘要

Praseodymium is one of the most important pigment materials for high-quality china and ceramics but its source minerals are not well known to geologists. Allanite, one of the REE-bearing minerals in nature, has a large coordination polyhedra for cations and favors the larger LREE ions such as praseodymium than other REE-bearing minerals that favor the smaller HKEE. We have tested some allanite crystals by CSIRO's micro-HXE to examine its possibility as a praseodymium source. Our result showed that allanite incorporates praseodymium at the order of 4000 to 5000 ppm and thus it is one of the good host of this element. We conclude that micro-PIXE is a viable quantitative tool for determining REE in allanite and other conventional REE sources in spite of the relatively poor minimum detection limitcompared to that for other elements.
