Overview

Minasgeraisite-(Y) is a discredited mineral species in the gadolinite supergroup with the chemical formula (Ca2Y2)□2(Be2B2)Si4O16(OH)4. Typically appearing as minute, purplish-lavender rosettes in granitic pegmatites, it was first identified at the José Pinto quarry in 1986 in Jaguaraçu, Minas Gerais, Brazil. The mineral was named after its type locality and approved by the International Mineralogical Association (IMA). Subsequent crystallographic and chemical analyses of the type material, as well as of comparable specimens from Norway and Central Europe, led to the mineral's discreditation in 2023. It is now regarded as a bismuth- and manganese-rich variety of hingganite-(Y).
