A novelty at Sainte Marie-aux- Mines 2016. Platy Ilmenite crystals with irregular pseudo-hexagonal contour and completely pseudomorphed by Rutile, coated by very sharp Titanite crystals that are bright, with very well defined faces and edges and coated in the back by Microcline crystals. The Titanite crystals have a very apparent pleochroism that shows a yellow color under led light but is greenish with natural or neon light. The process of replacement of Ilmenite by Rutile seems very similar to that of other localities with similar geological conditions (by example the Zambian Rutile) and it is due to hydrothermal processes at the site. These samples, very different from the Titanite previously known at Imilchil, have required an accurate analytical process.Imilchil area, Anti-Atlas, Er Rachidia Province, Meknès-Tafilalet Region, MoroccoFound in 2016Specimen size: 6.8 × 5.7 × 1.3 cm = 2.7” × 2.2” × 0.5”Main crystal size: 1 × 0.8 cm = 0.4” × 0.3”EF90AG9
