Analyzed specimen with report

Rich specimen formed by numerous spinel crystals showing octahedral form, black colour, very brilliant and well defined faces and edges. Sample is accompanied by the label of Douglas "Doug" Toland, with notes those indicates it could be gahnite or chromite, but the semi-quantitative analysis done with SEM-EDS microscopy shows that it is spinel, not identified in the mine before. It is accompanied by probably grossular and chlorite. A good specimen for the species and for this cold locality.

Size: 4.8 x 4.7 x 4.5 cm.

Very aesthetic stalactite of goethite totally covered with sharp lanceolated pyrolusite crystals, disposed in a very aerial shape, with an intense luster, colour between metallic gray to almost black. A notable specimen for the species and the locality.

Size: 6.8 x 3.5 x 2 cm.

Curious specimens of vanadinite showing yellow, slightly orange, hexagonal prismatic crystals, on which a thin layer of goethite has been deposited. At the same time, on this layer another generation of vanadinite and calcium-rich pyromorphite (phosphohedyphane), such as the attached analyzes show, we will send to the buyer. They are disposed on a matrix of goethite. Very interesting and different specimen from this classic Moroccan mine. Take a look to the SEM image of second generation crystals with an unusually rich facet...

Rich group of so called arsenatian vanadinite showing defined edges and curved faces, barrel-shaped and many of them doubly terminated, with the characteristic color of this variety. These samples appeared on the market in the late 1970s as pyromorphite, until they were correctly determined by XRD and SEM-EDS analysis. This specimen has been analyzed, just for info, showing As 3%weight and 8.7% in V. Old specimen, nowadays rare to find.

Tyrolite specimens from the Amorosa mine are a classic of Spanish mineralogy. In the cavities of the dolomitic matrix we find esthetic and brilliant aggregates of tabular, foliaceous crystals of tyrolite. The SEM-EDS analysis of this sample are consistent with those of other deposits, showing the presence of S and Zn in its composition. It is accompanied by chenevixite, an arsenate of copper and iron, olive green colour. We will send detailed analysis to the buyer.

Brilliant botryoidal hematite specimen. In the back side we observe very esthetic concentric growths of different colours, fibrous, of hematite. These pieces have been cleaned in origin with sand which eliminates the surface oxide layer to let us see these spherical forms of good size. Very curious Moroccan novelty.

Good botryoidal specimen of hematite. In the back side we observe very esthetic growths of different tones, fibrous, of hematite. These pieces are usually cleaned at the origin with sand, but in this case and because of the luster, we do not believe that it was. Very curious Moroccan novelty.

In the eastern part of the beach of Lapari there are the known septaria of Deba. The reef may have about 15 m, but it is not distinguished from the rest of the marly formation of the black flysch of Deba beach. The first publications on the septaria of Deba date from 1958. The upper part of the site has been totally destroyed by works, and in the part of the beach, foreign and local collectors collected numerous specimens. Currently this area has been declared of special protection within the coastal biotope Deba-Zumaia so the collection of septaria is absolutely prohibited [link]. Polished section.

Druse of very sharp baryte crystals showing developed and striated prismatic faces, truncated by pinacoids. The crystals are translucent, and color varies between colorless to yellowish. Excellent brilliance. Similar specimens were classified, many years ago, as hokutolite (a lead-rich baryte variety) but further analysis showed that there was only a minor lead content.

Good schorl specimen from the clssic locality of Cap de Creus, Girona. Some crystals showing a developed and faceted prism and terminal faces, some of them with good thickness. From this locality it is very difficult to obtain specimens if they do not appear in old collections, as it is the case, since it is totally forbidden to collect specimens in the area. This one belongs from the Manchion Collection and it is accompanied by the handwritten label.
