Abstract

The Semenov (1969) memoir on the mineralogy of the Ilímaussaq alkaline massif mentioned a number of minerals under preliminary names. The present status of these minerals is reported together with new data on ephesite, which was mentioned as white mica in 1969. The mineral described as white Zr-silicate is terskite, the white Nb-silicate is the new mineral Na-komarovite, the red Mn-silicate is Mn-Fe-sepiolite, and the Mn-palygorskite should now be termed yofortierite.
