U-Pb age of titanite from diorit of Osnytsky Block (Volyn Megablock of Ukrainian Shield)
The Osnytsky block is a constituent part of the Osnytsky-Mikashevytsky volcano-plutonic belt. The leading place in the geological structure of the Osnytsky block is occupied by the rock association, which includes a number of plutonic formations from ...

Timing of syn-orogenic, high-grade transtensional shear zone formation in the West Uusimaa Complex, Finland [PDF]
We present zircon and titanite U-Pb ages from granulite-facies transtensional shear zones and a greenschist facies strike-slip shear zone in the Karkkila-Vihti area, West Uusimaa. The zircon rim and titanite ages of c.

Dating Deformation with Titanite [PDF]
Directly dating deformation is a critical, unresolved challenge in tectonics. The mineral titanite (CaTiSiO5) is one of the best candidates for a “deformation chronometer”—a way to interpret dates in their microstructural context to directly date ...
