{{Short description|Rare form of tektite}}
[[File:Georgiaite 3.jpg|thumb|Georgiaite found in [Dodge County, GA](/source/Dodge_County%2C_Georgia) displaying olive green color.]]
'''Georgiaite''' is a rare form of [tektite](/source/tektite) found only in the state of [Georgia](/source/Georgia_(U.S._state)) in the southeastern United States. These tektites are found in part of the North American [strewn field](/source/strewn_field) coming from what is believed to be the [Chesapeake Bay impact crater](/source/Chesapeake_Bay_impact_crater) in the late [Eocene epoch](/source/Eocene) over 35 million years ago. Two strewn fields and tektite groups are currently associated with this impact: the black [bediasite](/source/bediasite)s in [Texas](/source/Texas) and the green georgiaites in Georgia.

Georgiaite has been found only in the eastern part of central Georgia with only between 1,000 and 2,500 known specimens {{As of|2018|lc=y}}. They are most commonly found as splash-form tektites.<ref name=":03">{{cite encyclopedia|access-date=2020-06-25|url=https://www.georgiaencyclopedia.org/articles/science-medicine/georgiaites|title=Georgiaites|publisher=Georgia Humanities and University of Georgia Press|first1=M.F.|last1=Roden|first2=E.|last2=Albin|language=en|encyclopedia=New Georgia Encyclopedia|date=2018}}</ref>

== Characteristics ==
Georgiaite specimens that have been found typically have a round shape and pock marked surfaces caused from the extreme conditions of its formation. Georgiaite most commonly is translucent with an olive green color. The size of Georgiaite can vary but most samples collected average around {{convert|2|in}} at most.<ref name=":12">{{Cite web|title=Georgia Tektites Listing {{!}} Meteorite Association Of Georgia|url=http://www.meteoriteassociationofgeorgia.org/GATektitesList.htm|access-date=2020-07-09|website=www.meteoriteassociationofgeorgia.org}}</ref> Georgiaite, like other [tektite](/source/tektite)s, are [silicate](/source/Silicate_mineral) [glass](/source/glass) and most closely resemble [obsidian](/source/obsidian).<ref name=":03" /><ref name=":22">{{Cite journal|last1=Albin|first1=E.F.|last2=Norman|first2=M.D.|last3=Roden|first3=M.|title=Major and trace element compositions of georgiaites: Clues to the source of North American tektites|date=2000|journal= Meteoritics & Planetary Science|volume=35|issue=4|pages=795–806|doi=10.1111/j.1945-5100.2000.tb01463.x|bibcode=2000M&PS...35..795A|doi-access=free}}</ref> Unlike other North American tektites, Georgiaite contains [silica](/source/Silicate) and [potassium](/source/potassium) while showing no traces of any other major [elements](/source/Elementary_particle).<ref>{{Cite journal|last=Albin|first=Edward Francis|date=September 1997|title=Georgiaites: Tektite Geochemistry and Stratigraphic Occurrence in East-Central Georgia|url=https://ui.adsabs.harvard.edu/abs/1997PhDT.........5A/abstract|journal=Ph.D. Thesis|language=en|pages=1168|bibcode=1997PhDT.........5A}}</ref>

== Locations ==
Georgiaite has been confirmed to be found only in central and eastern counties in [Georgia](/source/Georgia_(U.S._state)). The majority of all Georgiaite that has been collected has been from [Bleckley County, Georgia](/source/Bleckley_County%2C_Georgia) and [Dodge County, Georgia](/source/Dodge_County%2C_Georgia) but other surrounding counties have also found samples in smaller quantities.<ref name=":03" /><ref name=":12" />

== Collections ==
There are several known collections of Georgiaites used for educational purposes, geological study, and for the public to view. One such collection can be found at the [Smithsonian Natural History Museum](/source/National_Museum_of_Natural_History) in [Washington, D.C.](/source/Washington%2C_D.C.) There is also a large donated collection at the [Fernbank Museum of Natural History](/source/Fernbank_Museum_of_Natural_History) in [Atlanta, GA](/source/Atlanta).<ref name=":03" /><ref name=":12" /><ref name=":22" /> Georgiaite was first discovered by Dewey Horne and E.P. Henderson in 1938 in Dodge County, GA.<ref>{{Cite web |title=Ancestors of Horace Dewey Horne Sr. [3863] |url=https://freepages.rootsweb.com/~talbotfamilyhistory/genealogy/3863.htm |access-date=2025-12-20 |website=freepages.rootsweb.com}}</ref>
