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.

RM2498   Hydrozincite

Hermosa mine, Sel del Haya, Cobijón, Udías, Cantabria, Spain

Really good sized hydrozincite specimen from this classic Spanish mine, with botryoidal forms and beige tone. The specimens with these sizes are difficult to see today. This one comes from the A. Arguijo collection. The Hermosa or Sel del Haya mine was a lead and zinc exploitation whose activity was carried out mainly between 1855 and 1932, although in the decade from 1950 to 1960 some important works were carried out. Settled on dolomitic limestone from the Aptian, the main mineralization comprises lead and zinc, the latter being the most important, both in the form of carbonates and sulphides [link].

RM2245   Kyanite after andalucite

Touro - O Pino, A Coruña, Galícia, Spain

The specimens of this species have been known since ancient times as pseudomorphic kyanite after andalusite. Both species are polymorphic, so substitution is not a rare case. The label says "Santiago de Compostela", but from what we have investigated, it is the area of the Conceilhos de Touro and O Pino, to the E. of Santiago, where for decades this material was worked as kyanite. A piece with history ...
