A nomenclature scheme has been set up for the nordite supergroup of minerals, which have the general formula A2BXYZT6O17 and where A = Na; B = Na, Ca; X = Sr, Ca, Ba; Y = REE, Sr; Z = Zn, Fe, Mn, Mg and T = Si. The nordite supergroup includes nordite-(La), nordite-(Ce), ferronordite-(La), ferronordite-(Ce) and manganonordite-(Ce), as well as meieranite which is considered as an unassigned member of the nordite supergroup. In the known nordite-group minerals the Y site is occupied by rare earth elements (REE), while in meieranite the Y site is occupied by Sr. The dominant element on the tetrahedral Z site determines the prefix used in the mineral name. New rootnames must be given to species with a different dominant element on the A, B or X sites. Nordite supergroup minerals are orthorhombic, although nordite-group minerals and meieranite crystallise in the Pcca and P21nb space groups, respectively. The proposed nomenclature scheme for the nordite supergroup has been approved by the Commission on New Minerals, Nomenclature and Classification (CNMNC) of the International Mineralogical Association (IMA). In addition, new chemical and structural investigations were performed on nordite-(Ce) from Illutalik (Igdlutalik), South Greenland, leading to the first crystal structure refinement for nordite-(Ce).

已为诺迪特矿物超群建立命名方案，其通式为A 2 BXYZT 6 O 17且其中A = Na；B = Na, Ca; X = Sr、Ca、Ba；Y =稀土元素，锶；Z = Zn、Fe、Mn、Mg 和T = Si。北欧铁矿超群包括北欧铁矿-(La)、北欧铁矿-(Ce)、铁铁矿-(La)、铁铁矿-(Ce)和锰铁矿-(Ce)，以及被认为是北欧铁矿超群的未指定成员的镁铁矿。在已知的nordite族矿物中，Y位被稀土元素（REE）占据，而在meieranite中Y位点由 Sr 占据。四面体Z位点上的主要元素决定了矿物名称中使用的前缀。必须为在A、B或X站点上具有不同优势元素的物种指定新的根名称。Nordite 超群矿物是斜方晶系的，虽然 Nordite 群矿物和 meieranite 在Pcca和P 2 1 nb 中结晶空间群，分别。为诺德特超群提议的命名方案已获得国际矿物学协会 (IMA) 新矿物、命名和分类委员会 (CNMNC) 的批准。此外，对来自格陵兰岛南部 Illutalik (Igdlutalik) 的诺钛矿 (Ce) 进行了新的化学和结构研究，从而对诺钛矿 (Ce) 进行了首次晶体结构细化。
