Titanite encircling illmenite in an amphibolite-facies metabasalt.

Repost from last year: A titanite lozenge imaged both using a cellphone through the microscope ocular, and with a proper imaging system. It's surrounded mostly by quartz (+feldspar).
Likely from the Grenville, but from a teaching collection two generations of retired professors ago.Titanite can be part of the record of temperature, pressure, and timing of crystallization.

Repost from last year:
I've seen sphene! (Sounds better than "the rock is tippsy with titanite")Centimeter-size black sphene (titanite) with apatite (dark brown) and orthoclase feldspar (light brown). Folding pocket knife for scale.
From the Bancroft locality in Ontario, Canada. Grenville-aged (~1.2± billion years)

from the Rocky Mountain Association of Geologists:
Titanite: the Wedge-shaped Timepiece, by Ronald L. Parker#Titanite has a distinctive crystal form that it flaunts…
…titanite is among the very few minerals that enjoy a larger color dispersion than that of diamond…
Hayden, Watson & Wark established that the relative concentration of Zr 4+ in titanite is systematically related to pressure and temperature conditions.

yeah calcite is cool but have you considered a mineral that is not literally the most common one on earth #titanite #teamTitanite #mincup24

#MinCup24 R2M7: #Titanite versus #Calcite
This matchup is all about timing.
Titanite's main claim to fame is as an indicator mineral for everything from formation temperature, pressure and chronology. Calcite’s U-Pb dating can help constrain the timing of fault slip, and the minimum age of ancient ocean crusts and volcanic rocks
Time to choose a mineral!

#MinCup 24 R1 M13: #Proustite versus #Titanite
Proustite entices with its translucent ruby crystals.
Titanite can form in both igneous and metamorphic environments.
Which shall it be: deep red sulfide proustite, or important indicator mineral titanite?
