Abee is an enstatite chondrite meteorite that fell on 9 June 1952 in Alberta, Canada.
The Abee meteorite fell at 11:05 p.m. on 9 June 1952. A stone of 107 kilograms (236 lb) was recovered from a 6 ft (1.8 m) deep crater. [2]
It was found five days later in Harry Buryn's wheat field located in the community of Abee, Alberta, Canada; which is located in Thorhild County, along the Canadian National Railway and Highway 63, 16 kilometres (9.9 mi) north of Thorhild and 49 kilometres (30 mi) from Boyle.
Abee is classified as an enstatite chondrite with a petrologic type 4, thus belonging to the group EH4. [1] It is the only example in the world of an EH4 impact-melt breccia meteorite. [3]
A meteorite is a solid piece of debris from an object, such as a comet, asteroid, or meteoroid, that originates in outer space and survives its passage through the atmosphere to reach the surface of a planet or moon. When the original object enters the atmosphere, various factors such as friction, pressure, and chemical interactions with the atmospheric gases cause it to heat up and radiate energy. It then becomes a meteor and forms a fireball, also known as a shooting star; astronomers call the brightest examples "bolides". Once it settles on the larger body's surface, the meteor becomes a meteorite. Meteorites vary greatly in size. For geologists, a bolide is a meteorite large enough to create an impact crater.
A chondrite is a stony (non-metallic) meteorite that has not been modified, by either melting or differentiation of the parent body. They are formed when various types of dust and small grains in the early Solar System accreted to form primitive asteroids. Some such bodies that are captured in the planet's gravity well become the most common type of meteorite by arriving on a trajectory toward the planet's surface. Estimates for their contribution to the total meteorite population vary between 85.7% and 86.2%.
Impactite is rock created or modified by one or more impacts of a meteorite. Impactites are considered metamorphic rock, because their source materials were modified by the heat and pressure of the impact. On Earth, impactites consist primarily of modified terrestrial material, sometimes with pieces of the original meteorite.
The Sudbury Basin, also known as Sudbury Structure or the Sudbury Nickel Irruptive, is a major geological structure in Ontario, Canada. It is the third-largest known impact crater or astrobleme on Earth, as well as one of the oldest. The crater was formed 1.849 billion years ago in the Paleoproterozoic era.
Rochechouart impact structure or Rochechouart astrobleme is an impact structure in France. Erosion has over the millions of years has mostly destroyed its impact crater, the initial surface expression of the asteroid impact leaving highly deformed bedrock and fragments of the crater's floor as evidence of it.
Thorhild is a hamlet in Alberta, Canada within Thorhild County. It is located at the intersection of Highway 18 and Highway 827, approximately 86 kilometres (53 mi) north-by-east of the City of Edmonton.
Abee is a hamlet in Alberta, Canada within Thorhild County. It is located on the Canadian National Railway and Highway 63, approximately 16 kilometres (9.9 mi) northeast of Thorhild and 49 kilometres (30 mi) south of Boyle. It has an elevation of 665 metres (2,182 ft).
Vigarano Mainarda is a comune (municipality) in the Province of Ferrara in the Italian region Emilia-Romagna, located about 40 kilometres (25 mi) northeast of Bologna and about 9 kilometres (6 mi) west of Ferrara.
Keilite is an iron-magnesium sulfide mineral with the chemical formula (Fe,Mg)S) that is found in enstatite chondrites. Keilite is the iron-dominant analog of niningerite. Keilite is named after Klaus Keil.
Enstatite chondrites are a rare form of meteorite, rich in the mineral enstatite. Only about 200 E-Type chondrites are currently known, comprising about 2% of the chondrites that fall on Earth. There are two main subtypes: EH and EL, classified based on their iron content.
Adhi Kot is a meteorite that fell on 1 May 1919 in the Punjab region, now in Pakistan.
Neuschwanstein was an enstatite chondrite meteorite that fell to Earth on 6 April 2002 at 22:20:18 GMT near Neuschwanstein Castle, Bavaria, at the Germany–Austria border.
St-Robert is an ordinary chondrite meteorite fell on Quebec on June 14, 1994.
The Blithfield meteorite was found by Joseph Legree in Blithfield Township, Renfrew County, Ontario and measured about 8 centimetres (3.1 in) x 10 centimetres (3.9 in) x 13.5 centimetres (5.3 in). The main mass is now in the Canadian National collection, Ottawa. Blithfield is an enstatite chondrite, a group of very unusual meteorites that were formed in a very reducing atmosphere. It is a breccia, one of only five known enstatite chondrite breccias.
Peace River is a L6 chondrite meteorite fall on the morning of March 31, 1963.
Sinoite is rare mineral with the chemical formula Si2N2O. It was first found in 1905 in chondrite meteorites and identified as a distinct mineral in 1965. Sinoite crystallizes upon meteorite impact as grains smaller than 0.2 mm surrounded by Fe-Ni alloys and the mineral enstatite. It is named after its SiNO composition and can be prepared in the laboratory as a silicon oxynitride ceramic.
The Sutter's Mill meteorite is a carbonaceous chondrite which entered the Earth's atmosphere and broke up at about 07:51 Pacific Time on April 22, 2012, with fragments landing in the United States. The name comes from Sutter's Mill, a California Gold Rush site, near which some pieces were recovered. Meteor astronomer Peter Jenniskens assigned Sutter's Mill (SM) numbers to each meteorite, with the documented find location preserving information about where a given meteorite was located in the impacting meteoroid. As of May 2014, 79 fragments had been publicly documented with a find location. The largest (SM53) weighs 205 grams (7.2 oz), and the second largest (SM50) weighs 42 grams (1.5 oz).
The Zakłodzie meteorite is a stony-iron meteorite found in Poland in 1998. Its mass is 8.68 kilograms (19.1 lb). It is composed predominantly from enstatite and meteoric iron. Currently classified as an ungrouped enstatite achondrite its classification is still an ongoing scientific debate.
The Itqiy meteorite is an enstatite-rich stony-iron meteorite. It is classified as an enstatite chondrite of the EH group that was nearly melted and is therefore very unusual for that group. Other classifications have been proposed and are an ongoing scientific debate.
