RM1785   Galena

Eugènia mine, Bellmunt del Priorat, Tarragona, Catalunya, Spain

Nowadays galena specimens from this Catalan mine are very difficult to be found. This piece of good size is formed by a compact group of galena crystals, with dominant octahedral faces very visible, together with some of the cube. It shows fissures due to the own tensions of the specimen, but that do not affect (they even add interest) to the sample. It is accompanied by dolomite and calcite. A Spanish classic from a classic collection.


Size: 11.5 x 6.5 x 5.0 cm.
Main crystal: 7.3 x 4.2 cm.

RM645   Galena with dolomite and pyrite

Règia mine, Bellmunt del Priorat, Tarragona, Catalunya, Spain

A weakness, I admit. A cube-octahedral complex galena, defined edges, with polysynthetic growths on (111) faces. In one of them we can observe tiny crystals of pyrite and dolomite.
It comes from one of the classic mines of Catalonia: the Règia mine. In this mining area, occasionally, we could find small specimens but usually less defined. An opportunity to get a specimen from a classic Spanish locality.


Size: 4,2 x 4,0 x 1,8 cm.
Main crystal: 13 x 11 mm.
Found in ±1998.

 

RM1027   Rhodonite with pyroxmangite, todorokite and tefroite

Serrana mine, El Molar, Tarragona, Catalunya, Spain

This specimen is from my old field trips to the El Molar (Tarragona) area. In this sample we combine rhodonite (more granular appearance, crystalline) with pyroxmangite (more compact appearance). Accompanied by black veins of todorokite. The tephroite, scarce, appears as patches of brownish tone. These differentiations rhodonite-pyroxmangite are indicative, both minerals usually appear mixed.

It is an old mine we call generically as Serrana mine, although in fact there are two different mines, with two separate dumps, one corresponding to the actual Serrana mine (with horizontal works), while the other (closest to the river and with vertical works) would be known as Manganese mine.

 


Size: 5.2 x 4.8 x 3.7 cm.
Found in 1980's.

RM1026   Rhodonite with pyroxmangite, todorokite and tefroite

Serrana mine, El Molar, Tarragona, Catalunya, Spain

This specimen is from my old field trips to the El Molar (Tarragona) area. In this sample we combine rhodonite (more granular appearance, crystalline) with pyroxmangite (more compact appearance). Accompanied by black veins of todorokite. The tephroite, scarce, appears as patches of brownish tone in the manganese oxydes. These differentiations rhodonite-pyroxmangite are indicative, both minerals usually appear mixed.

It is an old mine we call generically as Serrana mine, although in fact there are two different mines, with two separate dumps, one corresponding to the actual Serrana mine (with horizontal works), while the other (closest to the river and with vertical works) would be known as Manganese mine.

RM2033   Smithsonite

Linda Mariquita Mine, El Molar, Tarragona, Catalunya, Spain

Specimen formed by small rounded crystals of smithsonite, with an intense pink color. These specimens stand out for the town and its intense color. The mine is now closed and in the process of restoration to make a part visitable.

RM1956   Acanthite with Silver

Balcoll mine, Pozo 2 (shaft 2), Falset, Tarragona, Catalunya, Spain

Acanthite in the specimens of the Balcoll mine, usually appears in small crystals. In this piece there are several groups of acanthite crystals of good size, showing facets of the cube and the octahedron, some of them have grown on skeletal aggregates of native silver. Very interesting for the species and for this classic Catalan locality. These specimens come from the findings of the last years of XXth century, being today very difficult to find them in the market and less with this quality.


Size: 6.8 x 3.8 x 2.4 cm.
Main crystal: 5 mm.

RM985   Silver

Balcoll mine, Falset, Tarragona, Catalunya, Spain

A very aesthetic specimen formed by a large group of silver crystals and filaments, forming spongy and skeletal growths. Good luster and a slightly tan tone. Stresses this specimen by several factors. One is its size and weight (on 40 g. or 1.4 oz.). Another is the abundance of this noble metal and perhaps the most interesting is that it is not an acidified sample. This is a plate obtained from a natural fissure in the host rock, with a lenticular and flattened structure. A very different piece from this classic Catalan locality.


Size: 7.8 x 4.0 x 2.5 cm.
Found in ± 1999.

RM737   Silver with acanthite

Balcoll mine, Pou 2, Falset, Tarragona, Catalunya, Spain

A very rich specimen of silver from a classic locality for the Catalan mineralogy. In this sample we could enjoy several groups of very sharp brilliant skeletal silver crystals. They are accompanied by acanthite aggregates of darker color. The specimen has been acidified with care since usually silver specimens become dark, but in this case, and looking at the date of collection, we can foresee a long stability. The label indicates that this material was mined in 1905, but the specimen was collected in 1998.

RM1974   Čechite

Maria Magdalena Mine, Rasa de l'Alzina, Ulldemolins, Tarragona, Catalunya, Spain

These specimens were found in a outcrop close to Maria Magdalena mine, close to the beautiful town of Ulldemolins (Tarragona, Catalonia). Probably, these crystals are the most defined crystals of Čechite worldwide. They are brilliant, black color and show a tabular shape defined by different order orthorhombic prisms and pinacoidal faces. Disposed very aerial on a fluorite matrix.
Čechite is very rare lead iron vanadate that is only found in a few places in the world and it is the first citation in the Iberian peninsula.
SEM-EDS and EPMA analysis show that, in some cases, on the crystal surface there is Cu2+ has been formed but the crystal is pure PbFe2+(VO4)(OH). In most specimens (all) from other localities the presence of manganese is important, but these specimens are Mn free. We will send more details to the buyer.


Size: 4 x 2 x 1.8 cm.
Main crystal: 1 mm.



 

RM1605   Čechite with fluorite

Maria Magdalena Mine, Rasa de l'Alzina, Ulldemolins, Tarragona, Catalunya, Spain

Probably čechite specimens from the "Rasa de l'Alzina" open pit works could be considered between the best crystals for the species worldwide. They are brilliant, black color and show a tabular shape defined by different order orthorhombic prisms and developed pinacoidal faces. They are disposed on a fluorite matrix. This finding is close to the Maria Magdalena mine, near of the beautiful town of Ulldemolins (Tarragona, Catalonia).
SEM-EDS and EPMA analysis show that, in some cases, on the čechite crystal surface we found copper content, but inside the crystal is near to pure  PbFe2+(VO4)(OH), with minor Zn(II). In most specimens from other localities the presence of manganese is important, but these specimens are Mn free.
