Sep 18, 2018 · Zircon is resistant to weathering, and thus is commonly found in clastic sedimentary rocks. Rare earth elements and radioactive isotopes such as uranium, thorium, and hafnium commonly substitute into the zircons crystal structure. Radioactive decay of these elements may damage the crystal structure and result in the mineral becoming metamict.
