Description: MUSEUM QUALITY METEORITE, HIGHEST QUALITY!!! Hello up for sale is a new find, with beautiful shape and exceptional features. This gorgeous individual weighs 630.00 grams, it has exceptional fluted regmaglypts and nice fresh fusion crust! This is a fresh and beautiful individual found in Algeria 2024, its unclassified and unstudied. This one comes with a COA card, thanks for your interest. Regmaglypts are shallow depressions or dimples that form on the surface of some meteorites as they pass through Earths atmosphere. They are probably formed by small vortices of hot gas carrying small droplets of molten meteorite that locally erode the surface. When a meteorite enters the Earth's atmosphere, friction raises the surface of the meteorite above its metling temperature. As the meteorite descends, it slows down, frictional heating decreases, and the melt quenches to form a fusion coating, a thin layer of dark glass. The fusion coating may be black or brown, dull or shiny on a recently fallen meteorite. After the meteorite has been on the Earth's surface for a while, the fusion coating may rust, giving the outside of the meteorite a reddish-brown coloring, or the fusion coating may erode off partially or completely. The fusion coating is a thin, discrete layer surrounding an interior that looks quite different from the fusion coating. Many Earth rocks can develop a weathing rind (from chemical weathering) on their exteriors that is similar in appearance to a fusion coating. However, there is rarely a sharp boundary between a weathering rind and the interior of the rock. In addition, tiny shrinkage cracks (too small to be visible in the images below) are fairly diagnostic for fusion crusts and are generally absent for weathering rinds. The surfaces of many meteorites develop shallow pits during entry into the Earth's atmosphere. These pits, known as regmaglypts, resemble thumb prints, and are usually better developed on iron meteorites than on stony meteorites Clemson edu says: Origins of Meteorites Not all meteorites are the same age. The oldest we have recorded clock in at 4.56 billion years old, especially those that come from asteroids. Meteorites from the moon tend to range from 2.9-4.5 billion years old, while those from Mars vary from 200 million to 4.5 billion years old. (8) Types of Meteorites Stonymeteorites are the most common type of meteorites. There are three subtypes of this group: chondrites, achondrites, and a third, more rare group, planetary achondrites. Chondrites are made of chondrules, which are droplets of melted rock which cooled in microgravity into tiny spheres (1). These are the most common type of stony meteorites and the most common type of meteorites on earth in general. Achondrites lack chondrules and form on planetary bodies with a distinct core and crust (8). They are less common than chondrites. Planetary achondrites are simply achondrites that come from the moon or Mars.
