#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!
