Bettertonite (original) (raw)
La bettertonita és un mineral de la classe dels arsenats. Rep el nom en honor de John Betterton (Londres, 1959), geòleg i mineralogista del museu educatiu Haslemere, a Surrey, Anglaterra, per les seves extenses contribucions a la caracterització de minerals de la mina de Penberthy Croft durant més de 30 anys.

| dbo:abstract | La bettertonita és un mineral de la classe dels arsenats. Rep el nom en honor de John Betterton (Londres, 1959), geòleg i mineralogista del museu educatiu Haslemere, a Surrey, Anglaterra, per les seves extenses contribucions a la caracterització de minerals de la mina de Penberthy Croft durant més de 30 anys. (ca) Bettertonite is a mineral of the arsenate category, named after John Betterton. He was a museum geologist and mineralogist at Haslemere Educational Museum in Surrey, England. Bettertonite is a white arsenate mineral with a formula of [Al6(AsO4)3(OH)9(H2O)5]・11H2O. Bettertonite is in the monoclinic system and has a heteropolyhedral layered structure type. It is a natural forming polyoxometalate. Bettertonite forms in clusters of radiating rectangular laths. Laths are thin and usually < 20 μm laterally. Laths are flat on {010}. Bettertonite is similar to penberthycroftyite and it transforms into penberthycroftyite at low temperatures (67-97 ℃). (en) Bettertonita mineral bat da. (eu) |
