Rutile
Rutile. Rutile is a common mineral in sand and one of the most important sources of titanium. The other important titanium-bearing mineral is ilmenite. It has very simple chemical composition (TiO 2 ). So it is an oxide like ilmenite and magnetite. Crystals are usually elongated and typically deep reddish brown although that color is best seen ...

Combined rutile–zircon thermometry and U–Pb
We then combine these thermometric results with in situ zircon and rutile U–Pb dating data to link U–Pb age to thermal conditions, and to detect if zircon and rutile grew in the peak and/or post-peak metamorphic stage. Finally, we discuss the implications for the tectonothermal evolution of the south Altyn Tagh HP-UHP metamorphic terrane. 2.

In a strategy similar to that used for zircon, rutile crystals were grown in the presence of zircon and quartz (or hydrous silicic melt) at 1–1.4 GPa and 675–1,450°C and analyzed for Zr by EMP. The experimental results were complemented by EMP analyses of rutile grains from six natural rocks of diverse origin spanning 0.35–3 GPa and 470 ...
