The Puerto Minguez ejecta refers to the impact ejecta from the 38 million years old twin (multiple) impact structure Azuara / Rubielos de la Cerida in Northern Spain, originating from the nearby Rubielos de la Cerida impact structure.
This is a strongly deformed limestone component (seldom different rock types) with significant displacements. Typical clast deformation looks looking like a loaf cut into slices but not fully broken into pieces. This is typical of a short-time dynamic deformation under high confining pressure.
The similar deformations are well known from the Ries crater impact ejecta that occurred in carbonate concretions and in the famous Ries Belemnites both embedded within soft Jurassic claystone. This sample shows a limestone clast partially sliced / fractured with prominent displacements in the range of up to 12 mm. The over all dimensions of this sample is 40x60 x125 mm and weighs 365 grams.
Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.
Here we have for you a superb looking Dhofar 020 classified meteorite weighing 82.14 grams. Its dimensions are 70x32x32 mm. Found 10 March 2000 in Dhofar, Oman, in the Arabian Peninsula this H4/5 classified chondrite has a TKW of 256 Kg with a shock stage of S4 and weathering grade of W3 by the Russian Academy of Sciences, USSR.
The following is an excerpt from Mark Bostick's review of this meteorite: "Dhofar 020 is a ordinary stone chondrite meteorite. The meteorite is high in free metal and therefore falls in the H class. S4 tells it is highly shocked. Slices of the meteorite, show veins of the cosmic impact created mineral Ringwoodite, although fractures in the stone tend to hide this some. It almost appears to me to have splinted upon impact. The meteorite falls in 4-5 petrology class, a reference to how metamorphed the meteorite is from its original state. This is judged by studying a thin section of the meteorite, most visually at the chondrules, a feature unique to stone meteorite. In a thin section under polarized light, pyroxene chondrules seem more common then their olivine pair. Still some regions in the meteorite show scattered patches of bright olivine inclusions. These are fairly rare, at least on my thin section, and most of the meteorite's olivine and pyroxene, some of the easier things to see in a thin section, appear to have went through a metamorphism, and have "melted" into the matrix and are at times undistinguishable."
This piece displays extremely well showing a beautiful crust, superb shape and good size. Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.
Here we have for you a nice looking individual cut fragment of a Sahara Desert NWA unclassified meteorite weighing 184 grams. Its dimensions are 77x62x28mm. This never classified North West Africa stone was found in the Sahara desert around 2000.
It's a good quality individual fragment NWA meteorite specimen. Some weathering shows the meteorite's time spent aging in the desert. Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.
This is a rare and fantastic 50.9 gram Libyan Desert Glass from Kuffra, Libya, with dimensions of 65x44x19 mm. Although its exact origin is still debated, the leading theory suggests it was formed by a high-energy event, such as a meteoric impact or airburst, that melted the desert sand directly where it lay, without being ejected into the atmosphere and re-entering. This results in different physical characteristics compared to tektites.
Libyan Desert Glass is found specifically in the Great Sand Sea of the Eastern Sahara, within a more localized area spanning parts of western Egypt and eastern Libya. Characterized by its yellow to greenish-yellow color, it lacks the aerodynamic shapes of tektites and often appears as irregularly shaped pieces. It is almost pure silica (around 98%) with very few impurities. Throughout history, it has been regarded as a mystical and powerful material, sometimes used in talismans and amulets.
This piece displays extremely well and is a quality translucent specimen. It has an aesthetic shape with a beautiful wind eroded body from the years spent in the Desert. Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.

The principal member of the Aragonite Group, aragonite is the second most common polymorph of natural calcium carbonate (the most common is calcite). It is significantly less widespread and abundant than calcite and is formed under a much narrower range of physiochemical conditions. It is metastable relative to calcite and often converts to calcite accompanying changes in the environment. It is nearly always a low-temperature, near surface mineral.

This is a superb looking Stony-iron or Mesosiderite class C classified meteorite named Northwest Africa NWA 1879 . This specimen is a part slice weighing 4.16 grams with dimensions of 22x17x4 mm.
This is a quote from Mr Hupé : "This is the NWA 1879, a rare C type Mesosiderite found in 2003 in Northwest Africa. This stony-iron type meteorite is beautiful because it is very fresh, has crystal clusters scattered throughout its matrix and has a great deal of elemental metal. NWA 1879 weighed 1,624 grams before preparation. About 31% was lost during cutting and polishing. There are several pairings to this meteorite in existence so the Total Known Weight (TKW) is unknown.
No expense was spared in the preparation of this meteorite. It was cut using a diamond blade in oil so that the silicates would not be plucked. When cutting this way the blade had to be redressed constantly to prevent the iron from loading up the cutting medium. It was coarse polished using a diamond lap, which needed the same treatment as the blade. It was then soaked in pure ethyl alcohol for days to extract the oil introduced during the cutting and polishing phases. A final dry polish was applied by hand, a very time consuming process. The final step was to clean it again with pure ethyl alcohol and dry it under a heat lamp providing great looking and stable specimens. This specimen comes with an identification card from The Hupé Collection."
This part slice displays extremely well and would be a beautiful addition to any new or existing collection. Comes protected in a gem jar with both a Canagem Collection and a The Hupé Collection specimen card.
