The MgTiO3-FeTiO3 join at high pressure and temperature
MgTiO3-FeTiO3 join high pressure temperature
2012/4/1
The phase relations at high pressure and high temperature for the FeTiO -MgTiO join were de-termined using several different experimental methods. Through a series of multi-anvil experiments,a phase ...
Stability of high-Al titanite from low-pressure calcsilicates in light of fluid and host-rock composition
high-Al titanite low-pressure fluid and host-rock
2012/3/31
Our recent paper noted that °∞some of the existing [M?ssbauer] studies (e.g., Fuchs et al. 1995) should be discounted due to th
fact that peak widths are less than the theoretical minimum imposed by ...
