Discrimination of TiO2 polymorphs in sedimentary and metamorphic rocks

Triebold, Silke; Luvizotto, George; Tolosana-Delgado, Raimon; Zack, Thomas; Eynatten, Hilmar (Contributions to Mineralogy and Petrology, 2010)

Investigation by Raman spectroscopy of samples from different geological settings shows that the occurrence of TiO2 polymorphs other than rutile can hardly be predicted, and furthermore, the occurrence of anatase is more ...
Rutile occurrence and trace element behavior in medium-grade metasedimentary rocks: example from the Erzgebirge, Germany

Luvizotto, George Luiz; Zack, Thomas; Triebold, Silke; von Eynatten, Hilmar (Mineralogy and Petrology, 2009)

Metamorphic textures in medium-grade (~500– 550°C) metasedimentary rocks from the Erzgebirge give evidence of prograde rutile crystallization from ilmenite. Newly-crystallized grains occur as rutile-rich polycrystalli ...
