hexagonal

Sneak preview of some recent research on elongated garnets with hexagonal symmetry!

Garnet is isometric, forming dodecahedral or trapezohedral crystals? Well, the ones shown in color below have hexagonal symmetry, with their long, three-fold rotation axes aligned at large angles to the rock matrix foliation.

Stay tuned for some recent results, integrating CT scanning, LA-ICP-MS mapping and in-situ Lu-Hf geochronology!
