丁道衡矿-(Ce)是在白云鄂博REE-Nb-Fe矿发现的一种新的稀土元素矿物,被视为是真正的珀硅铈钛矿(Perrierite)的同质多象体和硅钛铈矿(Chevkinite)亚族C(1)位上的钛类似物。同时,它还是自然界发现的首例硅钛铈矿亚族具P21/a空间群的天然产物。之后,在攀枝花V-Ti-Fe矿红格矿区找到一种几可全方位同白云鄂博产原型丁道衡矿-(Ce)对比,但空间群为C2/m的丁道衡矿-(Ce)变体,并作了全面、系统的矿物学研究。自此,参照先例,攀枝花产具C2/m空间群的丁道衡矿-(Ce)宜称C2/m丁道衡矿-(Ce);而白云鄂博原型丁道衡矿-(Ce)宜称P21/a丁道衡矿-(Ce)。C2/m丁道衡矿-(Ce)的发现与研究揭示,已有的硅钛铈族矿物何以具有C2/m变体和P21/a变体的成因解释,尚不能圆满诠释2种变体的形成。
Ding Daoheng Minerals - (Ce) is a new REE mineral discovered in the REE-Nb-Fe ore in the Bayan Obo and is considered as a true homogeneous multiphase of Perrierite with cerium Titanium analogues at the C (1) position of the subfamily Chevkinite. In the meantime, it is also the first natural product of the P21 / a space group found in nature. Afterwards, we found a small amount of Dingdaoheng ore - (Ce) variant, which can be compared with the prototype of Dingbaoyuan - Ce in the Bayan Obo, but the space group is C2 / m in the Hongge mining area of the V-Ti- And made a comprehensive and systematic mineralogy. Since then, according to the precedent, the Dingdaoheng Mine - (Ce) of C2 / m space group of Panzhihua production should be called C2 / m Dingdaoheng Mine - (Ce); and the Bayeobiao Dingdaoheng Mine - (Ce) should be called P21 / a Dingdaoheng Mine - (Ce). The discovery and study of C2 / m Dingdaoheng ore - (Ce) revealed that the existing explanation of the genesis of C2 / m and P21 / a variants of the silicotitanium cerium minerals has not been able to satisfactorily explain the formation of the two kinds of variants .
