What is the geologic origin of Cryolite, and could there be more? Cryolite occurs in syenite vein deposits (igneous rock which is quartz deficient) which had abundant amounts of fluorine There are 13 other known mineral specimens that contain primarily: Na, Al, F Cryolite is the most common mineral, due entirely to the Ivigtut deposit
geology - Is there a list of instances where mountains that have been . . . Cryolite was once present as a large deposit in Greenland, where it was mined as an aluminum ore and later for a flux in the electrowinning of aluminum from refined oxide ores In 1987 this source became too depleted for commercial mining to continue, and while the mineral still technically exists in Greenland and elsewhere it is now considered
Are there Rare Earth Elements in Ukraine? According the a United Nations report, Ukraine has significant deposits of rare earths In 2022, the Russian-language service of UN News reported that Ukraine’s deposits of rare earths accounted for approximately 5% of the world’s reserves
mineralogy - What determines the color of light emitted by . . . The light emitted by a mineral due to thermoluminescence is caused by electrons shedding extra energy obtained during radiation exposure; this can be in the form of heat, light, or ionising radiation

geology - Could evidence of a signal from an exocivilization be found . . . No, it is not possible The only thing I could think about is re de magnetisation of magnetic minerals Even then I'm not sure it's feasible, because you to form a magnetic field you need an electric current in motion, but that's a question for physics, not here
