baddeleyite, monazite, titanate and other accessory minerals. Dating of such minerals can provide quantitative constraints on the timing of geological processes including sedimentation, magmatism, deformation, metamorphism, mineralisation and alteration. Furthermore, U-Pb dating can be augmented with zircon Hf-O isotope analyses to.

Baddeleyite: Mineral information, data and localities.

EM chemical dating of baddeleyite is clearly best suited for Mesoproterozoic and older samples, but in cases where the U content is much higher (> ppm; e.g., Heaman and Machado, ) the technique could potentially be applied to reconnaissance dating of baddeleyite-bearing rocks as young as Ma.
