Археологичид 1629 онд Австралийн эрэг орчимд сүйрсэн Голландын Дорнод Энэтхэгийн компанийн “Батавиа” хөлгийн ачаанд байсан элсэн чулууг шинжилж, тухайн үеийн ложистикийн нарийн зохион байгуулалтыг илрүүлжээ.
Австралийн Көртин их сургуулийн геохимич Энтони Кларк болон түүний баг “Journal of Archaeological Science: Reports” сэтгүүлд нийтлүүлсэн судалгаандаа “Батавиа” хөлөгт тээвэрлэж явсан элсэн чулуун блокуудын гарал үүслийг тогтоохын тулд циркон эрдэсийн уран-хар тугалгын (U-Pb) аргаар нас тогтоох шинжилгээг ашиглажээ. Судалгаагаар хоорондоо ижил мэт харагдах чулуун блокууд нь Германы өөр өөр карьеруудаас, тухайлбал Бентхайм болон Обернкирхенээс гаралтай болохыг тогтоосон байна. Энэ нь тус компани чулууг зөвхөн ойр байрлах газраас бус, 140 километрийн зайтай газруудаас ч сонгон авч, нэгдсэн сүлжээгээр дамжуулан хол зайд тээвэрлэдэг байсныг баталж байгаа юм.
Голландын Дорнод Энэтхэгийн компани Ази дахь төв байр болох Батавиа хотыг (одоогийн Жакарта) байгуулах бүтээн байгуулалтад шаардлагатай материалыг ийнхүү өндөр зохион байгуулалттайгаар цуглуулж, тээвэрлэж байжээ. Эрдэмтдийн таамаглаж буйгаар эдгээр ачааг Амстердам дахь төв цэгт нэгтгэн дэлхий даяар тээвэрлэдэг байсан аж.
Энэхүү олдвор нь 400 жилийн тэртээх колоничлолын дэд бүтцийг хөгжүүлэхэд ашиглагдаж байсан түүхий эдийн хангамжийн сүлжээний нарийн төвөгтэй байдлыг харуулж байна. Археологич Кориоли Соутерын онцолсноор, сүйрсэн хөлөг онгоцны үлдэгдэл нь өнөөг хүртэл түүхийн шинэ баримтуудыг дэлгэсээр байгаа бөгөөд дээрх аргачлалыг бусад хөлөг онгоцны ачааг судлахад ч ашиглах боломжтой юм.

The wreck of the Dutch East India Company ship Batavia, which sank off the coast of Western Australia in 1629, is one of the most infamous in the region’s history – primarily because of the massacre and mutiny that took place amongst the survivors.
Researchers from Australia and Germany have now published a paper in the Journal of Archaeological Science: Reports that analyzes a different aspect of the Batavia‘s story: what exactly it had in its hold.
The ship was carrying prefabricated sandstone blocks, thousands of bricks, and other building materials when it was wrecked, plus a treasure trove of silver coins and jewels.
Of particular interest to the researchers was where these sandstone blocks had been sourced from – and the answer to that question has revealed a surprising strategic choice by the Dutch East India Company four centuries ago.
“Historical records are incomplete, and after nearly 400 years underwater, these stones can look very similar, making them difficult to identify,” says geochemist Anthony Clarke from Curtin University in Australia.
“We wanted to know if tiny mineral grains could give us a reliable fingerprint of where the stone formed, and help reveal how the Dutch East India Company sourced and transported materials across its global network.”
The team used a technique called detrital zircon U-Pb dating to uncover details of the rock’s composition that couldn’t be ascertained from conventional imagery and analysis.
This dating technique essentially looks at the uranium trapped in the zircon of the sandstone to assess its age. When the researchers compared samples from two sandstone blocks against each other, they found their patterns didn’t match.
The samples did tally with rock found in modern-day quarries: one sandstone block was from the Bentheim quarry in Germany, and one was from the Obernkirchen quarry, also in Germany. Both are known to have been used by the Dutch East India Company.
“By analysing microscopic zircon minerals within the stone, we discovered that blocks which looked almost identical actually came from different quarry regions in what is now Germany,” says Clarke.
“We found these stones were sourced from at least two different quarry areas, then brought together into a single shipment before being sent halfway around the world in a highly organized supply chain more than 400 years ago.”
That’s significant because it’s evidence of the company not simply using rocks from whichever quarry was closest. This was a coordinated, thought-through supply chain, using quarries some 140 kilometers (87 miles) apart.
One of the biggest trading outfits of the time, the Dutch East India Company moved materials all around the world, with these particular sandstone blocks intended for use at the company’s Asian headquarters in Batavia (now Jakarta), where the shipwrecked vessel’s name comes from.
“The research also highlights the logistical complexity behind the Dutch East India Company’s expansion, including how building materials were sourced, consolidated and transported across vast distances to support colonial infrastructure,” says Clarke.
According to the researchers, the cargo of the Batavia may have been consolidated in a central hub in Amsterdam, although that’s an educated guess.
They’re now planning to use these techniques to study more of the sandstone and brick recovered from the wreck, which should reveal more details – and perhaps more secrets – about the logistics behind its operations. The approach could also be used on other shipwrecks with stone cargo.
It’s more evidence that improving geochemical analysis technology gives us a better picture of the past – whether it’s in terms of workshop production, methods of warfare, or the movement of goods.

“Nearly 400 years after Batavia sank, the famous ship is still revealing new stories,” says archaeologist Corioli Souter from the Western Australian Museum.
The research has been published in the Journal of Archaeological Science: Reports.
