RM2655   Quartz (amethyst var.) and fluorite

Sant Marçal (Matagalls) mines, Sant Marçal, Massís del Montseny, Viladrau, Girona, Catalunya, Spain

Very "brilliant" specimen in the shape of a druse, with a pegmatitic matrix, accompanied by yellow fluorite crystals and upholstered with really brilliant quartz crystals, with an amethyst tone. These specimens were a rarity then and today.

The Sant Marçal mines (also known as Matagalls) are located in the Montseny massif, on the eastern slope of the Matagalls peak (1,700m). The works are between about 1,250 to 1,350 m of altitude. The municipal term corresponds to Viladrau. Mining in this type of deposits in this area and surrounding areas has focused on the extraction of minerals of Pb, Zn, F and Ba. Together with the Osor and Tagamanent deposits, the Rigròs vein of Sant Marçal mines is one of the most important in terms of the extraction of fluorite. Mines were operated until the mid-1990s and have been partially restored. Currently this area belongs to the Montseny Natural Park, so the collection of specimens is totally prohibited.
