RM2969 Fluorite and quartz
Sant Marçal (Matagalls) mines, Sant Marçal, Massís del Montseny, Viladrau, Girona, Catalunya, SpainFluorite specimens from Sant Marçal mines usually appear as aggregates of cubic crystals, defined, sometimes sprinkled or partially covered by quartz crystals. Yellow to greenish tones are the usual ones. Specimens with violet to bluish or green colors (depending on the type of incident light) are much less frequent and highly appreciated by collectors. These specimens we offer were collected at the beginning of the 70s. In this specimen we can observe cubic crystals with this bluish to greyish tone, translucent and disposed on a characteristic ochy "pegmatite" matrix. They are partially covered with small but brilliant quartz crystals.
The Sant Marçal mines (also known as Matagalls mines) are located in the Montseny massif, on the eastern slope of the Matagalls peak (1,700 m). Mining works were carried out at 1,250 to 1,350 m of altitude. The municipality corresponds to Viladrau. Mining in this type of deposits in this area and surrounding areas had been focused on the extraction of minerals of Pb, Zn, F and Ba. Together with the Osor and Tagamanent deposits, the Rigròs main vein from Sant Marçal mines is one of the most important in terms of fluorite extraction. Although there are other less thin mineralized veins in the area. These veins are embedded in granodiorite rock, which locally present metric dikes with a pegmatite texture. the granodiorites are usually altered to "sauló" (coarse-grained sand with micas, clays and quartz grains) and in some specimens it forms part of the matrix. The paragenesis of these veins: fluorite, baryte, galena, pyrite, chalcopyrite and quartz (often amethyst variety). They were mined until the mid-90s and have been partially restored. Currently this area belongs to the Montseny Natural Park, so the collection of specimens is totally prohibited.
Size: 5.5 x 3.5 x 3.2 cm.
Main crystal: 9 mm. edge.
Found in ±1970.
RM2968 Hematite
Monte de Hierro Mines, Cerro del Hierro, San Nicolás del Puerto, Sevilla, Andalucía, SpainThis is a very good sized specimen of hematite from the group of mines called "Monte de Hierro" (Iron Hill), whose concessions were between the terms of San Nicolás del Puerto and Constantina, although most of the surface is found in the first municipality mentioned. This specimen belongs from the Trigo collection (Mataró) and according to the label it was extracted in 1989 by Julián García.
Size: 9.3 x 7.4 x 4 cm.
Found in ±1989.

RM2967 Gmelinite and analcime
Little Deerpark Quarry, Glenarm, Co. Antrim, Northern Ireland, United KingdomThese aggregates of hexagonal gmelinite crystals are a classic of Northern Ireland mineralogy. In this specimen we can enjoy a vacuole covered by orange crystals, very well defined and brilliant. They are accompanied by small analcime crystals, richly faceted and transparent. Gmelinite specimens from this quarry were analyzed by X-ray fluorescence and SEM-EDS by Stephen Moreton. The results indicated that both gmelinite-Ca and gmelinite-Na are present and even zoned in the same crystal.
Size: 7.9 x 7.4 x 3.2 cm.
Main crystal: 4.3 mm.

RM2965 Pitticite, 'Ganomatite' - Scorodite, Galena
St. Andreasberg, Braunlage, Goslar, Lower Saxony, GermanyThis is another one of those specimens from old collections, as evidenced by the various accompanying labels, that contain discredited or dubious mineral names. Even so, the historical and scientific interest it presents has made us offer it.
In the piece we observe a core of galena with halos of alteration of the vein in the socket. In the cavities we find numerous well-formed crystals of cerussite. And in some areas we observe greenish and honeyed tones probably corresponding to pyromorphite, but also to possible scorodite. The 'ganomatite' is considered a scorodite with impurities, while the pitticite is a questionable species formed by amorphous hydrated iron arsenate. Although this last mineral is currently accepted, it is questioned.
Size: 5.4 x 4 x 3.9 cm.
Found in ±1977.

RM2956 Ilmenite and pyrite
Tio Mine, Havre-Saint-Pierre, Minganie RCM, Québec, CanadaAs is often the case with old labels, the localities are sometimes discrepant with the data we currently have available on the Internet. This historic specimen of ilmenite, from the Joan Astor collection was acquired in 1976 from Joan Montal (former mineral seller from Vilafranca del Penedés), provides us with a label indicating the locality of Saint-Urbain. At the time of documenting this piece, we have found the photo of an ilmenite from Havre-Saint-Pierre (an area further northeast of Saint-Urbain) with a very similar shape and accompanying species and, most notable, it is indicated that it was collected in situ during a visit in 1979 (view), when our specimen dates from 1976. Furthermore, both specimens are formed by aggregates of ilmenite crystals with a few pyrite crystals embeded.

RM2948 Celestine and sulphur
Machów mine, Tarnobrzeg City Co., Subcarpathian Voivodeship, PolandIn this specimen we can observe a group of celestine crystals with a highly developed prism and small but well defined terminal faces. They are transparent, which allows us to observe a marked color zoning with honeyed tones in the lower middle part and colorless in the upper part. They are disposed on a matrix with sulphur. This specimen belongs from the former Joan Astor collection and we will send the handwritten label to the buyer.
Abstract from Gradowski et al. (1992): "Sulphur deposits being surface mined in the Tarnobrzeg area of Poland formed post-depositionally in the vuggy limestone layer above gypsum and anhydrite beds. Sulphur was deposited mostly as powder but also as coarsely crystalline masses and as free-growing crystals. Other materials present in the sulphur-bearing horizon include calcite, gypsum, quartz, aluminum oxide, celestine, and barite. Mineral specimens of these minerals collected at the mine are described."
