EM52AG5: Titanite on Rutile after Ilmenite and with Microcline

A novelty at Sainte Marie-aux- Mines 2016. Characteristically platy Ilmenite crystals with an irregular contour, pseudomorphed by Rutile and completely 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 natural or neon light. The process of replacement of Ilmenite by Rutile seems very similar to that of other localities with similar geological conditions ( for 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 been analyzed and we’ll send to the buyer the information and documentation previously obtained about the process and also a copy of the analyses done on the different species present in the sample.

TC78EZX: Titanite on Rutile after Ilmenite and with Microcline

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.
