Fun Fact: Boltwoodite is easily recognised by its bright yellow crystals.
Introduction: Boltwoodite is named after Bertram Borden Boltwood, an American radiochemist from Yale University. Superb crystals are mined in Namibia, easily recognised by its bright yellow crystals, needle-like and sprayed- in arrangement , similar to radiating balls. It occurs in uranium deposits and alaskite veins.
Distribution: Goanikontes in the Rössing Area produces magnificent examples of boltwoodite where it is mined specifically for mineral specimens. The criss-cross network of white alaskite dykes in the Khan River Gorge east of Swakopmund is an unusual example of rocks containing uranium minerals.
