www.mindat.org/min-4049.htmlNote that the mineral was accepted automaticaly, without detailed investigation and description of type material. Only a single Nd-dominant analysis was published. In other words, Tundrite-(Nd) is a very doubtful mineral, which nobody saw and nobody have. Consequently nobody was able to repeat results of its chemical analysis.

en.wikipedia.org/wiki/List_of_minerals_T_(complete)This list includes those recognised minerals beginning with the letter T.The International Mineralogical Association is the international group that recognises new minerals and new mineral names, however minerals discovered before 1959 did not go through the official naming procedure, although some minerals published previously have been either confirmed or discredited since that date.
rruff-2.geo.arizona.edu/uploads/CM46_413.pdfanother occurrence of tundrite-group minerals from the Ilfmaussaq complex, South Greenland. Cerium-dominant members, previously named "tundrite", were renamed tundrite-(Ce), and Nd-dominant compositions were described as the new mineral species tundrite-(Nd). The authors recognized the presence of major amounts of sodium by chemical analysis ...
