RM2528   Carbonate-hydroxylapatite, montgomeryite and goethite

Elvira mine (Rocabruna mines), Bruguers, Gavà, Barcelona, Catalunya, Spain

Many years ago, these crystal aggregates were classified as brushite, but later analysis indicated that it was hydroxylapatite with carbonate groups. Fluorapatite is not common in Bruguers. These globular aggregates are disposed on an upholstered matrix with bright green microcrystals of montgomeryite. The matrix is goethite. From the J. Astor collection, formerly col.

RM2532   Quartz with kaolinite and limonite

Serrabal mine, Vedra, A Coruña, Galícia, Spain

Almost floating druse of quartz crystals forming pineapple growths, with a good luster and a slightly yellowish hue. On the backside, also crystallized, we can see the typical kaolinite layer of this deposit. It is accompanied by a limonite nodule that was probably pyrite.
These specimens were collected in this A Coruña quarry that exploits quartz, one of the main mines in the world due to the quality and quantity of its reserves. The mine was discovered in 1968 by three Galicians who gave their name (from their surnames SEñarís, RAma and BALboa) to the concession and who found it while exploring these mountains in the Pico Sacro area in search of "seixo" (from the Galician: hard white rock) of good quality.

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].

RM2466   Graphite

Tres Hermanos mine, Pilotuerto, Tineo, Asturias, Spain

Nowadays, graphite specimens from this classic Asturian locality are very difficult to be found. These specimens show contiguous columns, with greasy luster and defined hexagonal forms. The crystal habit of natural graphite in most cases is determined by its highly anisotropic, layered structure. However, anomalous habits of graphite,determined not only by its structure, but also by the peculiarities of the growth environment, are frequently encountered, and optimization of the space available when solidifying forming columns.
