Found October 30, 1983
30° 18′ 42′ N., 86° 10′ W. A large, unbroken, 11.3 kg stone was found about 200 meters from the high tide line and 1 meter below the surface by two treasure hunters, Mr. Phillip Gibson and Dr. John Green, while using Element that readily forms cations and has metallic bonds; sometimes said to be similar to a cation in a cloud of electrons. The metals are one of the three groups of elements as distinguished by their ionization and bonding properties, along with the metalloids and nonmetals.

They were searching for Spanish armor in an ancient Indian refuse heap near Grayton Beach, Florida when they found the 23 × 18 × 17.5 cm dark-brown stone. The stone is without a distinct Melted exterior of a meteorite that forms when it passes through Earth’s atmosphere. Friction with the air will raise a meteorite’s surface temperature upwards of 4800 K (8180 °F) and will melt (ablate) the surface minerals and flow backwards over the surface as shown in the Lafayette meteorite photograph below.

The mesodesmic bonds of the silicon tetrahedron allow extensive polymerization and silicates are classified according to the amount of linking that occurs between the encrustation formed during its extended residence in wet sand.

In November 2013, ‘Grayton ’s meteoric moment: 30 years later, resident recalls discovery’ was published by Jennie McKeon in ‘The Walton Sun’, which includes an interview with Phil Gibson, one of the original finders of the Grayton meteorite. Due in part to the intense temperature and moisture conditions in the state of Florida, only four meteorites have been found there to date, in addition to two recovered falls. Besides Grayton Beach, approximately 1 kg of L4 fragments were brought up in a net offshore of Lake Okechobee, a 502 g H4 stone was plowed up in Eustis, and a 41.8 kg H5 stone was found in Bonita Springs. In 2004, November 8 at 6:15 P.M., Orlando resident Donna Shuford heard a meteorite bounce off her car and hit the side of her house. Fragments composing an ~180 g Most common type of achondrite meteorite and a member of the HED group. Eucrites are basalts composed primarily of pigeonite and anorthite (An60-98). Eucrites have been placed into three subgroups based on mineralogical and chemical differences. • Non-cumulate eucrites represent the upper crust that solidified on a magma ocean after Click on Term to Read More were recovered. In 2016, January 24 at 10:27 A.M., numerous eyewitnesses observed a bright fireball over northern Florida near the Osceola National Forest. Utilizing radar images from several stations, a group of hunters successfully plotted the Meteorite seen to fall. Such meteorites are usually collected soon after falling and are not affected by terrestrial weathering (Weathering = 0). Beginning in 2014 (date needs confirmation), the NomComm adopted the use of the terms "probable fall" and "confirmed fall" to provide better insight into the meteorite's history.

Chondrites are comprised mostly of Fe- and Mg-bearing silicate minerals (found in both chondrules and fine grained matrix), free Fe/Ni metal (found in various states like large blebs, small grains and/or even chondrule rims), and various refractory inclusions (such Click on Term to Read More fell within a forested wetlands region delimiting a strewn field of approximately 5 miles × 1 mile.
