Titanite on Rutile after Ilmenite and on Microcline

TC180ET

A novelty at Sainte Marie-aux-Mines 2016. Platy Ilmenite crystals with irregular contours and completely pseudomorphed by Rutile, coated by very sharp Titanite crystals that are bright, with very well defined faces and edges, and with a very apparent pleochroism that shows a yellow color under led light but is greenish with daylight or neon light. Partially coated by Microcline crystals. 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. We’ll send to the buyer a copy of the analyses done on the different species present in the samples.
