They claim that villagers that were part of the wealthy Kingdom of Colchis, which existed from the sixth to the first centuries BC, used sheepskin to capture gold from mountain streams in the area.
The fleece was used to line the bottom of the sandy stream beds, trapping any tiny grains of gold that built up there. The technique is a variation on panning used elsewhere in the world.
This, they say, would have lead to sheepskins that were imprinted with flakes of gold and could have given rise to stories of a golden fleece.
Historic artifacts, including a bronze sculpture of a bird with a ram's head, that were found in the villages of Svaneti also lend support that the kingdom was the source of the myth.
He said: ‘The phenomena of the “Golden Fleece”, according to our research, is connected with the sheepskin technique of recovering placer gold (gold that has built up in sand deposits).
‘The end result of this technique of gold recovery river gravels was a gold imprinted sheepskin, giving rise to the romantic and unidentified phenomena of the “Golden Fleece” in the civilized world.
‘We think, from our investigations, that the bedrock and placer gold contents of this region give grounds to believe that there was enough gold in this region to describe Svaneti as “the country rich of this noble metal”.
Dr Okrostsvaridze and colleagues from the Ivane Javakhishvili Tbilisi State University in Georgia, conducted a widespread survey of gold deposits in the Svaneti region.
They report in the journal Quaternary International that they used remote sensing and analysed more than 1,000 rock and gravel samples to assess the gold content in the area.
They found that placer gold, where nuggets and flakes sink to the bottom of a stream bed, were extensively exposed throughout the time of the Kingdom of Colchis.
Some ancient sources, and modern academics, have said it could have belonged to the Vani people of Colchis, whose territory was in the middle of the kingdom, but others have predicted it was the Svans who lived in the mountainous north.

Dr Okrostsvaridze, however, points to golden artifacts found in the villages around Svaneti as evidence that they had sophisticated mining and meteorological skills.
These include a unique golden lion sculpture that has been dated back to the second millennium BC.
'Our work shows that the gold content in the rivers sands of this region are sufficiently large to give grounds for the creation of legends.'
Geological surveys by Dr Okrostsvaridze and his team reveal that gold deposits in many areas that were historically mined have been replenished as streams have continued to wash them down the mountainsides.
Indeed, he said that some locals still use traditional techniques to obtain gold from the rivers in the area and it may even be possible for modern day Argonauts to find a golden fleece of their own today.
He said: ‘Our work has confirmed that Svaneti is a region, uniquely, where the locals still wash gold from alluvial placers through modern domestic, wooden vessels or pans with holes in the bottom and unto a sheepskin or fleece which collects the fine particulate gold.’
