The inclusion of grothite in the zircon from granitoids of the crystalline basement of the Southern Yamal Peninsula

Vestnik MGTU, 2019
Grothite – rare F-Al-rich type of titanite – has been found in accessory zircon from the granitoids of the pre-Jurassic basement of the Verkhnerechensky oil-gas area (in the southern part of the Yamal Peninsula) as a result of the study.

Compositional Variations of Titanite: A Possible New Tool for Cyprus-Type Volcanogenic Massive Sulfide Deposit Prospecting

Geosciences, 2020
Titanite in submarine mafic magmatic rocks of Neotethyan origin was studied to reveal its possible use as an indicator mineral of modern Cyprus-type VMS deposits.

Geochemical behavior of chromium in minerals of high-Mg rocks, associated with granitoid massifs of the Urals

Литосфера, 2019
Research subject. High-magnesium rocks associated with the granitoid massifs of the Urals are represented by gabbro-diorites and their melanocratic varieties (hornblendites), as well as by diorites and quartz diorites.

Elastic softening of metamict titanite CaTiSiO5: Radiation damage and annealing [PDF]

, 2011
We have measured the elastic response of radiation-damaged titanite, CaTiSiO5, as a function of thermal annealing. We estimate the bulk modulus of the damaged samples (~24% amorphous) to be 85 GPa, which is much softer than for undamaged crystalline ...
