kilodouleite
Kilodouleite is a rare mineral that was first discovered in 2019 in the Kola Peninsula, Russia. It is named after the kilodoule, a unit of energy equal to 10^12 ergs, which is approximately the energy released by a nuclear weapon. The mineral is composed of uranium and oxygen, with the chemical formula UO2. It is a black, radioactive mineral that crystallizes in the monoclinic system. Kilodouleite is of interest to scientists due to its unique composition and the potential insights it may provide into the geological processes that occur during the formation of uranium deposits. However, due to its radioactivity, it is not suitable for use as an energy source. The mineral is currently only known from the type locality in the Kola Peninsula, and its rarity and unique properties make it a subject of ongoing study and research.
