Advances in Crystal-Chemistry Study of Type Bafertisite from Bayan Obo, China
摘要
Abstract
Bafertisite is the first new mineral found in the Bayan Obo iron mine, Inner Mongolia, China. To date, it has been over half a century, but the expression concerned with the formula of type befertisite and unit-cell parameters are still controversial, some even very different. This study compiled all the expressions related to the formula. Combined with the structural refinements of type bafertisite and minerals alike conducted home and abroad and the preliminarily-published chemical compositions, we calculated and re-evaluated atoms per formula unit (apfu) using three calculation methods. Based on this research, the crystal chemical formula of type bafertisite was improved tentatively. In addition, the unit-cell parameters are also in dispute. Based on the preliminary refinement to the crystal structure and enlightenment from crystal structure of the same mineral in East Sea, our improvement to the unit-cell parameters of type bafertisite has solid evidence. Therefore, it is necessary to conduct in-depth research on the type bafertisite. One thing is sure that the crystal chemical formula, unit-cell parameters, and crystal structure need to determination, refinement and modification.关键词
