RM2500   Variscite

Can Palomeres, Malgrat de Mar, Barcelona, Catalunya, Spain

Variscite is a hydrated aluminum phosphate present in different Catalan deposits found in the Catalan Coastal Mountain Ranges. Well-known sites are those of the Serra de Miramar, in Tarragona; Bruguers, Gavà and Cerdanyola in Barcelona, along with the well-known site of Montcada i Reixac, close to the city of Barcelona. Less well known are the deposits in the northernmost area of these mountain ranges, between Malgrat de Mar and Pineda de Mar area. This specimen comes from the Malgrat area and was found in surveys near Can Palomeres. The variscite vein shows a green color with yellow to whitish tones. It is included in slates with other phosphates such as phosphosiderite and strengite. We can observe so-called ptygmatic folds produced by the entry of a viscous fluid (variscite) into a less viscous one.

RM2254   Actinolite

Can Serrat-La Mena mines, Sant Feliu de Buixalleu, Girona, Catalunya, Spain

These rare specimens of actinolite correspond to those cited by L. Thomas (Els Minerals de Catalunya, year 1920) and E. Bareche (Els Minerals de Catalunya, Segle XX, year 2005: "Where it really appears in large quantities is inside the well they made near the creek in the mines of Can Serrat, road from Hostalric to Arbúcies, in the district of Sant Feliu de Buixalleu. It is shiny, greenish in color; we collected and kept specimens that were examined by Don Ramón Adan de Yarza, which confirmed our identification". It is a skarn formed by the contact of the granodiorites and the limestone of the Paleozoic. From the former Arguijo collection.
