3.1 IMA 23-G – redefinition of georgeite

(Mike S. Rumsey)

Proposal 23-G is accepted, and georgeite is redefined as an amorphous alpha-phase hydroxide with the generic formula [Cu(OH)_2−x(H₂O)_x][CO₃]${}_{x/\mathrm{2}}$.

3.2 IMA 23-H – revalidation of testibiopalladite

(Louis J. Cabri and Qing-Lin Liang)

Proposal 23-H is accepted, and testibiopalladite, originally described from a unspecified occurrence in China (Geochimica, 3, 169–181, 1974), is recognized as a valid mineral species with ideal formula PdSbTe.
