All these examples quoted are chemically similar to the 
aegirite-augite-granite from Sviatoy 'Noss. The quartz- 
lindöite from Frön contains merely arfvedsonitic hornblende 
as a mafic mineral. In the soda-granite from Iviangusat 
there is catophorite-like hornblende and ”aegirite-augite. 
IV and V contain aegirite and riebeckite. In the aegirite- 
granite from Miask the mafic mineral is pyroxene with domi- 
nant aegirite-molecules, the rock being thus mineralogically 
almost identical with the rock under consideration. All 
analyses quoted agree in showing a deficiency in alumina-.
