Kernowite: In November 2020, approximately two major world events occurred. Firstly, Joseph R. Biden Jr. and his dog Major were elected as the 46th president and president’s dog of the United States of America. Secondly, the International Mineralogical Association approved a new mineral, kernowite, Cu2Fe3+(AsO4)(OH)4⋅4H2O, which was described by M. Rumsey from the Natural History Museum in L ...[Read More]
