Carmeltazite is a rare oxide mineral. Its first discovery on Earth was announced in 2019, after it was found in Zebulun Valley in Israel.[1][2] The chemical formula for carmeltazite is ZrAl2Ti4O11.[3]
The International Mineralogical Association's Commission on New Minerals and Mineral Names approved the registration of the mineral under application 2018-103. The name is a combination of the location it was found (Mount Carmel) and the major elements (titanium, aluminium and zirconium).[4] It has properties similar to Allendeite.[5]
