Jadarite is a white, powdery, non-radioactive monoclinic mineral[1], whose chemical formula is sodium lithium boron silicate hydroxide: LiNaSiB3O7(OH) or Na2OLi2O(SiO2)2(B2O3)3H2O. It was discovered in November 2006, in drill holes in the Jadar Valley (Serbian Cyrillic: Јадар, Yaddar) in Serbia, from which it is named. It was confirmed as a new mineral after scientists at the Natural History Museum in London and the National Research Council of Canada conducted tests on it[2]. Exploration geologists from the dual listed company Rio Tinto Exploration discovered the mineral as small rounded nodules in drill core, and after being unable to match it with previously known minerals enlisted the expertise of Dr. Chris Stanley, from the Natural History Museum, who later described it as being unique to mineralogy.[3]


Jadarite in fiction

Jadarite's chemical formula is very close to the formula invented for the fictional substance kryptonite in the 2006 film Superman Returns. This coincidence attracted mass-media attention, and jadarite was covered by ABC, BBC, CNN, Washington Post, and Yahoo, among others.

The new mineral, unlike the fictional material in the movie, does not contain fluorine, does not emit electromagnetic radiation, and is white rather than green (although, in the Superman comics, there is a white colored variety of kryptonite). In all other respects the chemistry matches that of the rock containing kryptonite in the movie. The jadarite fluoresces a pinkish-orange color when exposed to UV light.[4]

Uses for jadarite

According to Dr. Stanley, jadarite would have some commercial value if sufficient deposits of it are found. Jadarite contains boron and lithium, two elements with many uses. Processed radioactive waste is encapsuled by borosilicate glass, while lithium is used in the manufacture of lithium-ion batteries.[5]
