Naujakasite Ilímaussaq Intrusive Complex, Narsaq, ...
Description: Naujakasite Ilímaussaq Intrusive Complex, Narsaq, Greenland FoV: 2,5 x 2 cm A strange mineral that formed instead of nepheline in certain parts of the hyper-agpaitic magma (=low silica, high sodium) of the Ilímaussaq Intrusion. In spite of not containing any rare elements, it is practically not found anywhere else on Earth. More info above my other Naujakasite photo that shows a single crystal. On this piece the colour is more fresh, greenish.
