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)
