1933 O. B. Bøggild in Meddelelser om Grønland 92 ix. 7 (title) Igalikite and naujakasite, two new minerals from Greenland.
1933 O. B. Bøggild in Meddelelser om Grønland 92 ix. 7 Among the minerals collected by G. Flink on his mineralogical journey in 1897 there is a specimen labelled ‘Chorite?’ by Flink. The locality is stated to be Naujakasik... The specimen containing the naujakasite was probably found loose on the ground.
1960 Mineral. Abstr. 14 370/2 Naujakasite, formerly only known from a loose boulder, has now been found in situ at Tuperssuatsiaq and the northern part of the Ilímaussaq batholith.
1967 Meddelelser om Grønland 181 vi. 14 Naujakasite alters easily through several stages to analcite.
1997 Mineral. Mag. 61 485 The most highly developed, hyperagpaitic lujavrites of the Ilimaussaq complex have been formed from melts with extreme concentrations of sodium and volatiles resulting in the formation of naujakasite instead of nepheline.
