Description: Aragonite is a carbonate mineral, orthorhombic mineral species of calcium carbonate but with a crystal structure different from those of Vaterite and Calcite, the other two polymorphs of the same composition. Also known as Aragon spar. The sample is generally banded due to the inclusion, at several levels (corresponding to certain stages of deposition) of impurities consisting of clay minerals, iron or manganese oxy-hydroxides, iron sulphides and organic substances.

Formula: Mg3(Si2O5)(OH)4

Description: There are three principal forms of Serpentine minerals: Lizardite, Antigorite, and Chrysotile, all with the approximate composition Mg3Si2O5(OH)4. The most abundant is Lizardite and the least is Chrysotile, but the latter is perhaps the best known as it commonly occurs in veins of silky fibers and has been the most important source of commercial asbestos.

Its mechanical strength combined with thermal stability and low thermal conductivity made asbestos and asbestos composites useful in a wide range of important products. However, it is now known that inhalation of asbestos dust is a serious health hazard (it may cause asbestosis or pleural mesothelioma).

Description: Goethite is a common iron oxide mineral and is a frequent matrix material for other more aesthetic minerals. Goethite is most often found in botryoidal, reniform, or stalactitic aggregates of radiating crystals or ball-like crystals. Goethite commonly forms a pseudomorph (i.e., one mineral that chemically replaces another mineral without changing the external form of the original mineral) after other minerals, especially Marcasite, Pyrite, Siderite, and Gypsum.

Goethite is named after Johann Wolfgang von Goethe (1749-1832), the famed German poet, philosopher, biologist, and mineral enthusiast.

Description: The name Diamond refers to its hardness (Greek - adamas, invincible) and has rank 10 on the Mohs scale. There is nothing comparable to it in hardness. Its cutting resistance is 4 times greater than that of Ruby and Sapphire, the gemstone next in hardness after Diamond. This allows one to cut diamonds with diamond and/or with diamond powder. Because of the perfect cleavage, care must be taken not to accidentally bang against an edge of a diamond, and also when setting it. His very strong luster sometimes enables the experienced eye to differentiate between a diamond and its imitations. Diamond is generally insensitive to chemical reactions. High temperatures, on the other hand, can induce etchings on the facets.

Size: 7 x 5.5 x 2 cm

Formula: Vanadinite - Pb5(VO4)3Cl; Baryte - BaSO4

Description: Vanadinite is an important ore of vanadium (V) and a minor source of the lead (Pb). Vanadinite usually forms where lead minerals are oxidized (as secondary mineral), often in areas with an arid climate. It is commonly associated with the oxidation of galena.

Baryte is typically found as thick to thin tabular or bladed crystals, usually in clusters with the crystals growing parallel to one another, or nearly so. It receives its name from the Greek word ‘barys‘ which means ‘heavy’. This name is in response to barite’s high specific gravity of 4.5, which is exceptional for a nonmetallic mineral.

Some of the white baryte is coated with dark grey manganese oxides.

Although it appears hexagonal, it is actually a ditrigonal prism. The upper surfaces of the specimen are all and cleavage planes. The basal surface is actually a saw cut, but demonstrates that the crystal is zoned. The apparent pitting on the crystal faces is an artefact of the scanning process - they are caused by more transparent sections of the crystal.carbonatehexagonalG

About photomacro-photogrammetry: The limits between close-up, macro, micro, etc. are arbitrary, we can find different definitions at different sources. This is an endless discussion. In general, the division (arbitrary) is based on the equipment used to take the pictures.

below than 1:1 ratio (e.g. 1:2) is a close-up photogrammetry
greater than 1:1 ratio (e.g. 5:1) is a photomacro-photogrammetry (sometimes the term macro-photogrammetry is used)
by using microscope optics is a photomicro-photogrammetry (regardless of the magnification factor)

Description: This specimen reminds me of the book of Antoine de Saint-Exupery - Citadelle.

Galena is the primary ore mineral of lead, used since ancient times. Galena is one of the most abundant and widely distributed sulfide minerals. The Galena is known for its ‘mirror-metallic’ luster and for the stepped structure. This specimen shows well-developed cubic crystals in staggered growth with defined edges. The crystals have intense shiny-metallic luster - in my opinion, one of the most ‘problematic’ sample.

Cleavage fragments of Galena - are one of the most diagnostic properties of Galena is its ability to break by cleavage in three directions that intersect at right angles. This forms cleavage fragments that are cubic and rectangular in shape.

Dolomitehttps://sketchfab.com/3d-models/dolomite-eaaf248e70504e699f11e02b7929186cEDUROCK - EDUCATIONAL VIRTUAL ROCK COLLECTIONDolomite is a common rock-forming calcium magnesium carbonate mineral. It is the primary component of the sedimentary rock known as dolostone and the metamorphic rock known as dolomitic marble. Limestone that contains some dolomite is known as dolomitic limestone.

Dolomite is rarely found in modern sedimentary environments, but dolostones are very common in the rock record. They can be geographically extensive and hundreds to thousands of meters thick. Most rocks that are rich in dolomite were originally deposited as calcium carbonate muds that were postdepositionally altered by magnesium-rich pore water to form dolomite.

Dolomite is also a common mineral in hydrothermal veins. There it is often associated with barite, fluorite, pyrite, chalcopyrite, galena, or sphalerite. In these veins it often occurs as rhombohedral crystals which sometimes have curved faces.

Sideritehttps://sketchfab.com/3d-models/siderite-abde5496ab2b4bf0b78e91d50f46819dEDUROCK - EDUCATIONAL VIRTUAL ROCK COLLECTIONSiderite is a mineral composed of iron(II) carbonate (FeCO3). It takes its name from the Greek word sideros, “iron”. It is a valuable iron mineral, since it is 48% iron and contains no sulfur or phosphorus. Zinc, magnesium and manganese commonly substitute for the iron resulting in the siderite-smithsonite, siderite-magnesite and siderite-rhodochrosite solid solution series.

Siderite has Mohs hardness of 3.75-4.25, a specific gravity of 3.96, a white streak and a vitreous lustre or pearly luster. Siderite is antiferromagnetic below its Néel temperature of 37 K which can assist in its identification.

It crystallizes in the trigonal crystal system, and are rhombohedral in shape, typically with curved and striated faces. It also occurs in masses. Color ranges from yellow to dark brown or black, the latter being due to the presence of manganese.
