Abstract
Baddeleyite, calzirtite, zircon and zirconian garnet were found in skarns at Fuka, Okayama Prefecture, Japan. They occur in association with grandite garnet, vesuvianite, diopside, wollastonite and perovskite. The chemical compositions of baddeleyite, calzirtite and zircon are nearly ideal except for small amounts of HfO2. Zirconian garnets are rich in titanium and contain up to 7.3wt. percent of ZrO2. These minerals occur in the contaminated rocks which formed from monzonite magma through hybridization during the formation of skarns.
