My Mineral Collection
I show off a representative sample of nearly all of the crystals, rocks, minerals, and gemstones in my mineral collection. All of these crystals and gemstones are from worldwide localities. I love my passion for geology and have been collecting minerals ever since I was 10-years old. EACH OF THE MINERALS IN ORDER: -Beryl: Aquamarine (North Carolina), Emerald (Brazil), Heliodor (Brazil), Bixbite or Red Beryl (Utah)- An ore of the alkaline metal Beryllium. Occurs in blue to blue-green(Aquamarine), Green (Emerald), Yellow to Orange (Heliodor), Red to Red-Purple (Bixbite), Orange-Pink (Pezzotaite), White to Clear (Goshenite), Bicolor (Blue-Pink, and Polychrome (Blue-Green-Yellow) hexagonal crystals. -Kyanite (Brazil)- A silicate mineral that forms in blue blade-like crystals. -Topaz: Brown Imperial Topaz (Pakistan), Blue Topaz (Brazil), Red Topaz (Mexico), Champange Topaz (Utah)- A common pegmatite mineral. Blue Topaz is often heat treated or irradited for jewelry to give an intense blue color. -Chrysocolla (Arizona)- A copper silicate hydrate mineral that forms with either Quartz or Azurite. -Feldspar: Labradorite (Madagascar), Amazonite (Brazil), Moonstone (India)- The most common mineral in the Earth's crust and can be either be Orhtoclase (Calcium) or Plaigoclase (Sodium or Potassium) depending on the mineral's chemistry. -Rainbow Opal (Australia) -Smithsonite (Mexico) -Apophyllite (India) -Vesuvianite or Idocrase (Quebec) -Vanadinite (Arizona) -Adamite (Mexico ...

EX Lupi
The fading light of a flaring young star has shed light on a puzzle involving crystals and comets... For the most part, the universe changes very slowly compared to, well, us. The stars appear much the same today as they did to our ancestors. So its a rare treat when astronomers actually catch a star 'in the act' of doing something unexpected, especially when it helps solve a long-standing puzzle. The star of this special event is about 500 light years away and known as EX Lupi. Its probably a close match to what our own Sun was like in its infancy almost 5 billion years ago. Early in 2008 it flared dramatically in brightness, due to material from its disk falling onto the central star. The stars brightness increased by a factor of 100, heating the disk far from the star. It appears that tiny dust particles far out in the disk melted slightly, or annealed. As they cooled they took on a new crystalline structure. This is the first time astronomers have ever caught crystals in the act of forming in a circumstellar disk. So how is it possible to detect such tiny crystals around a star thats so far away? Well, dust is a specialty of NASAs Spitzer Space Telescope. Not only has Spitzer shown that dusty disks are common around young stars, its infrared spectrograph also allows us to study their compositions. By splitting up its light into a spectrum, astronomers can look for unique features, like spectral fingerprints, that correspond to specific minerals. This first observation ...

Clay minerals are typically formed over long periods of time by the gradual chemical weathering of rocks, usually silicate-bearing, by low concentrations of carbonic acid and other diluted solvents. These solvents, usually acidic, migrate through the weathering rock after leaching through upper weathered layers. In addition to the weathering process, some clay minerals are formed by hydrothermal activity. It is a soft, earthy, usually white mineral (dioctahedral phyllosilicate clay), produced by the chemical weathering of aluminium silicate minerals like feldspar. We build the primary frames from heavy ductile iron castings (nominal section thickness is no less than 1.25"). The base construction features 8-inch wide flange beams.

The copper sulfate solution (the pregnant leach solution) is then stripped of copper via a solvent extraction and electrowinning (SX-EW) plant, with the barred (denuded) sulfuric acid recycled back on to the heaps. Alternatively, the copper can be precipitated out of the pregnant solution by contacting it with scrap iron; a process called cementation. Cement copper is normally less pure than SX-EW copper. Commonly sulfuric acid is used as a leachant for copper oxide, although it is possible to use water, particularly for ores rich in ultra-soluble sulfate minerals.[citation needed] You should find that copper has been reduced from +2 to +1; oxygen (in the gas) has been reduced from 0 to -2 (oxygen in the SiO2 is unchanged); and three of the four sulphurs on the left-hand side have been oxidised from -2 to +4 (the other is unchanged). So, to deposit one copper ion at the cathode needs two electrons ...

Green sand beach in Hawaii
Papakōlea Beach is located in a bay half circled by Puʻu Mahana, a cinder cone formed over 49000 years ago and associated with the southwest rift of Mauna Loa. Since its last eruption, the cinder cone has partially collapsed and been partially eroded by the ocean. The beach is sometimes named after the cinder cone, and sometimes after the area of land called Papakōlea, which comes from papa kōlea, which means plover flats in the Hawaiian language. Papakōlea is the area near the crater where the Pacific Golden Plover (Pluvialis fulva) are sometimes seen in winter. The cinder cone is rich in olivine, a silicate mineral containing iron and magnesium, also known as peridot when of gem quality. Olivine is a common mineral component of Hawaiian lavas and one of the first crystals to form as magma cools. Olivine is locally known as "Hawaiian Diamond" and is notably found in Oʻahu's famous Diamond Head landmark. The source of the green coloration of the beach sands is due to the olivine crystals which are winnowed from the eroding headland by the action of the sea. Olivine, being denser and tougher than the ash fragments, glass and black pyroxene of the rest of the rocks and lava flows, tends to accumulate on the beach whereas the usual volcanic sand is swept out to sea. Although these crystals are eventually washed away as well, the constant erosion of the cinder cone ensures a steady supply of sand for the foreseeable future—eventually, however, the supply will run out and the ...

Komatiite
This komatiite from southern Africa is one the Earth's oldest volcanic rocks. It formed from extremely hot lava (~1600° C) 3.6 billion years ago. It is dominated Fe & Mg rich silicate minerals derived from melting of the mantle. Ultramafic volcanic rocks like these are largely restricted to the Archean Eon 2.5 to 4 billion years ago. Their chemistry suggests that the earth was much hotter during its early history -- with the mantle being roughly 500°C hotter than today. The elongate crystals of Olivine and Pyroxene, create a fabric called spinifex texture -- indicating rapid quenching of the lava in water.

Serpentinite
Serpentinite is a low grade metamorphic rock dominated by FE /Mg -- rich silicate minerals from the deep mantle portion of an oceanic plate; this specimen was thrust on to the continental margin of eastern North America in present day Vermont by the plate tectonic collision of a volcanic island arc along eastern Proto - North America during the Taconic orogeny, ~440 mya -- and is currently mined as a popular building stone called Verde Antique. The parent mantle rock was altered by elevated temperature, pressure and reaction with water and carbon dioxide to form a variety of green serpentine minerals; this process of serpentinization results in the oxidation of iron and the release of free hydrogen ions initiating the formation of methane -- this has been suggested as an abiotic mechanism for explaining the recent detection of methane on Mars -- the hydrogen ions may also power the metabolism of bacteria and methane-producing archaea and was likely an important process for early life on Earth.

Charlotte Home Inspector Talks About Asbestos
www.homeinspectioncarolina.com Asbestos (from Greek ἄσβεστος meaning "unquenchable" or "inextinguishable") is a set of six naturally occurring silicate minerals exploited commercially for their desirable physical properties. They all have in common their asbestiform habit, long, (1 thin fibrous crystals. The inhalation of asbestos fibres can cause serious illnesses, including malignant lung cancer, mesothelioma (a formerly rare cancer strongly associated with exposure to asbestos), and asbestosis (a type of pneumoconiosis). Since January 1, 2005, the European Union has banned all use of asbestos[1] and extraction, manufacture and processing of asbestos products.[2] For environmental samples, one must normally resort to electron microscopy for positive identification.[3] Today, gravimetric and PCM/PLM techniques are employed. However, the latter techniques cannot readily identify the smallest, most hazardous, fibers, because they are limited to PM10 particulate size evaluation, which completely ignores ultrafine particles (UFPs). Asbestos became increasingly popular among manufacturers and builders in the late 19th century because of its sound absorption, average tensile strength, and its resistance to heat, electrical and chemical damage. When asbestos is used for its resistance to fire or heat, the fibres are often mixed with cement or woven into fabric or mats. Asbestos was used in some products for its heat resistance, and in the past was used on electric oven and ...
