Mineralogical Association of Canada

In our March issue, we feature eight brand new minerals; just when you'd finished memorizing the existing list!Find out about alterite and magnesioalteraite (oxalate minerals from Arizona, USA), perchiazziite (a rosasite-malachite group mineral from Italy), four new minerals from the Redmond Mine, North Carolina, USA (two thiosulfates, and two OPb 4 -chain-based minerals), and finally ronpetersonite (BaWO 4 ) from Canada's Yukon, named for the very same Ron Peterson we featured in a special thematic issue of the CJMP in July 2023.In addition, we learn about the exploration implications of columbite-group minerals from the Chinese Altai, inclusions in placer Pt-Fe alloys in Ecuador, hollow bulbous gypsum structures reported from Alberta (Canada), and clarification on the status of the mineral testibiopalladite (PdSbTe); spoiler alert: it's a Sb-analogue of michenerite, but a valid mineral in its own right.In addition, we feature regional geology, in the form of a study of the tectono-metamorphic evolution of the Kluane Schist, from the northern cordillera of the Yukon.
