The discovery of the Aletai meteorite did not happen in a single moment. A single iron mass weighing roughly 28 tonnes stood on the northern Xinjiang grasslands for more than a century before anyone understood what it was — one fragment of what would prove to be among the largest meteorite falls on Earth. Local herdsmen called it the Silver Camel. Russian and early Western geological reports cataloged it as “Armanty.” For over a hundred years it was treated as an isolated curiosity — one large iron rock in a remote landscape.
It took until 2017 for the scientific community to formally recognize that this mass was not alone. It was one fragment of the longest contiguous meteorite strewn field on Earth: the Aletai fall, scattered across more than four hundred kilometres of the Altay Prefecture. This is the timeline of how that recognition came together — a record assembled over 124 years from local finds, geochemical pairing, and three successive revisions of the official meteorite record.
The Silver Camel That Stood for a Century
The first known fragment of the Aletai parent body was recorded in 1898, in Yinniugou, Qinghe County, within the Altay Prefecture of the Xinjiang Uyghur Autonomous Region. The discoverers are unconfirmed in the scientific literature; the find is generally attributed to local herdsmen crossing the Gobi terrain.
The mass weighed an estimated 28 tonnes. Its weather-polished metallic surface and its distinctive two-humped morphology earned it a local name among the Kazakh population: the Silver Camel. For decades it remained where it lay — too large to move, too remote to study.
For more than a century after 1898, the Armanty mass was classified as a single, isolated meteorite. No one suspected it belonged to a far larger event. In 1965, authorities organized the transport of the 28-tonne mass out of Qinghe County to Urumqi, where it remains on display today in the front plaza of the Xinjiang Geological and Mineral Museum.
The Twenty-First-Century Finds
The picture changed dramatically after 2004. Over the following seventeen years, a series of multi-tonne iron masses was recovered along a linear corridor stretching hundreds of kilometres — too many, too aligned, to be coincidence.
| Mass | Year | Weight | Note |
|---|---|---|---|
| Armanty | 1898 | 28 tonnes | The Silver Camel; relocated to Urumqi in 1965 |
| Ulasitai | 2004 | 430 kg | Found by geologist Li Xiaodong |
| Xinjiang (b) | 2005 | 35 kg | Acquired from an anonymous finder |
| Wuxilike | 2011 | 5 tonnes | Found by a local farmer |
| Akebulake | 2011 | 18 tonnes | Found June 17 by Hailati Ayisa and Jiaerheng Habudehai |
| WuQilike | 2021 | 23 tonnes | Held by the Aletai Department of Natural Resources |
The named masses alone account for roughly 74 tonnes; the total known weight of the fall approaches 100 tonnes, distributed across a strewn field measured at 425 to 430 kilometres along its long axis.
The 18-tonne Akebulake mass carried a complicated human record. While the formal 2011 discovery is credited to Hailati Ayisa and Jiaerheng Habudehai, competing accounts exist — a local official reported observing the “strange stone” during a 2004 survey, and a local pastoral family asserted their relatives had encountered it as early as 1986. The 2011 expedition is what finally triggered formal scientific reporting and the mass’s relocation.
The Name That Took Three Bulletins
The harder problem was not finding the masses. It was proving they belonged together — and getting that conclusion into the official record. That process took three separate revisions of the Meteoritical Bulletin, the database maintained by the Meteoritical Society.
The Ulasitai mass was first approved as a distinct meteorite in MB 90 (2006). Two years later, geochemical analysis published by Xu et al. (2008) in Meteoritics & Planetary Science demonstrated that Ulasitai was paired with the Armanty mass — they shared the same parent body. As a result, MB 95 (2009) abolished the name “Ulasitai,” reducing it to a synonym for Armanty.
The decisive revision came with MB 105 in September 2017. By then the Wuxilike and Akebulake masses had been verified as sharing the same geochemical signatures as Armanty. The Meteoritical Society undertook a major nomenclatural revision: MB 105 established “Aletai” as the single name covering the entire strewn field and all its associated masses. The historic name “Armanty” was discredited as a distinct meteorite and relegated to synonym status, alongside “Xinjiang (b),” “Ulasitai,” and “Xinjiang 008.”
In other words, the meteorite most of the world had known by other names for over a century was officially renamed — and unified — only in 2017.
The Science That Closed the Case
The final confirmation arrived in 2022, when a study published in Science Advances resolved the question that had made the Aletai fall so difficult to interpret: how could fragments be scattered across more than four hundred kilometres without a massive terminal impact crater?
The research team combined three independent methods. Whole-rock trace element geochemistry confirmed that the Akebulake, WuQilike, and Armanty masses shared identical kamacite bandwidths of roughly 0.9 to 1.4 millimetres and the same anomalous concentrations of gold, cobalt, and iridium — establishing geochemical pairing. Cosmogenic radionuclide dating estimated the fragments’ exposure history and original size. And numerical aerodynamic modelling, using Monte Carlo simulations, reconstructed the fall itself.
The conclusion was that the Aletai asteroid entered Earth’s atmosphere at an unusually shallow angle — between 6.5 and 7.3 degrees — and traced what the authors described as a “stone-skipping” trajectory, skimming the upper atmosphere rather than plunging into the ground. The body broke apart and dissipated its energy across the 425-to-430-kilometre path, dropping its iron cores along the way. The paper, “A unique stone skipping–like trajectory of asteroid Aletai,” was published in Science Advances on June 24, 2022 (DOI: 10.1126/sciadv.abm8890).
The same metallographic analysis placed the parent body’s cooling rate at 10 to 40 degrees Celsius per million years — confirming that the Aletai irons crystallized slowly, deep within the metallic core of a differentiated planetesimal. For more on what that structure looks like and why it makes Aletai distinct, see what makes Aletai different.
Where the Masses Are Today
Because of their scientific and cultural value, the major Aletai masses are now held under formal protection rather than left in the field.
The 28-tonne Armanty mass remains the centrepiece of the Xinjiang Geological and Mineral Museum in Urumqi. When the 18-tonne Akebulake mass was recovered in 2011, the regional government built a road into the high-altitude terrain to extract it, and it now sits at Aletai City Hall. The 23-tonne WuQilike mass is held by the Aletai Department of Natural Resources, with a small specimen deposited at the Purple Mountain Observatory. Beyond the masses themselves, regional authorities have designated areas of the strewn field — including the Takeshiken crater area — as protected geological sites.
The result is a recovery history that is, unusually, documented at almost every step: the finds, the pairings, the renaming, and the institutions that now hold the material.
Why the Aletai Meteorite’s Discovery Trail Matters
For anyone evaluating a meteorite, history is not decoration — it is evidence. A specimen whose recovery, classification, and custody are recorded in public scientific sources can be checked. A specimen without that trail cannot.
The Aletai fall is one of the better-documented iron meteorites in this respect. Its masses appear by name in successive Meteoritical Bulletin entries. Its pairing is established in peer-reviewed literature. Its trajectory is modelled in a published study. Its largest fragments are held in named museums and government collections. None of this requires taking a seller’s word for anything — it can be read against the public record.

A History You Can Carry
A material’s story does not end when it enters the official record. The same documented history that scientists assembled over 124 years is what gives a finished piece its credibility.
Every wearable piece made from Aletai material inherits this trail: a named fall, a classified composition, and a recovery history written down in public sources rather than asserted in marketing. That is the opposite of mysticism. It is verifiability — the ability to point to where a claim comes from.
This is the standard Movalor works to: every piece is made from Aletai iron meteorite, a fall documented in the Meteoritical Bulletin Database and described in the peer-reviewed literature. The history above is not a brand story. It is the public record that any owner can read for themselves.

FAQ (plain text)
When was the Aletai meteorite discovered? The first known fragment — the 28-tonne Armanty mass — was recorded in 1898 in Qinghe County, Xinjiang. For more than a century it was treated as an isolated meteorite. Additional masses were recovered between 2004 and 2021, and the unified “Aletai” classification was only established in 2017.
How many masses make up the Aletai strewn field? At least seven major masses have been recovered, including Armanty (28 tonnes), WuQilike (23 tonnes), Akebulake (18 tonnes), Wuxilike (5 tonnes), Ulasitai (430 kg), and smaller fragments. Together they account for a total known weight approaching 100 tonnes across a strewn field of 425 to 430 kilometres.
When was the name “Aletai” officially established? The Meteoritical Society established “Aletai” as the overarching name for the entire strewn field in Meteoritical Bulletin 105, published in September 2017. Earlier names such as “Armanty” and “Ulasitai” were reclassified as synonyms.
What did the 2022 Science Advances study show? The study, published June 24, 2022, used geochemistry, radionuclide dating, and aerodynamic modelling to confirm that the scattered masses share a single parent body. It concluded that the asteroid entered the atmosphere at a shallow 6.5–7.3 degree angle on a “stone-skipping” trajectory, explaining how fragments spread across 425–430 kilometres without forming a large impact crater.
Is the Aletai meteorite well documented? Yes. Its masses are recorded by name in successive Meteoritical Bulletin entries, its pairing is established in peer-reviewed literature, and its largest fragments are held in named museums and government collections in Xinjiang.
