Ancient slag with Ludlockite and Nealite crystals; Laurion, Greece – 1 kg
This 1 kg lot consists of historical slag pieces from the ancient metallurgical dumps of Oxygono in the renowned Laurion mining district of Greece. The porous, reddish-grey to dark brown copper slag exhibits numerous cavities and inclusions where rare secondary arsenate minerals have crystallized. Of particular interest are fine crystal formations of Ludlockite and Nealite – two highly uncommon arsenate species.
The unique combination of ancient smelting material and rare mineral diversity makes these slag samples valuable not only to collectors of historical mining artifacts but also to micromount specialists interested in post-mining mineral formation. Each lot includes several larger fragments, suitable for microscopic study or further processing.
Geology & Origin
Located south of Athens, the Laurion district is one of the oldest documented mining regions in Europe. Silver and lead ores were already being extracted and smelted there in the 5th century BCE, leaving behind substantial slag deposits. These anthropogenic rocks remain geochemically active to this day, allowing rare secondary minerals to form through slow oxidation processes.
Among the most notable species are Ludlockite (a complex lead–iron arsenate) and Nealite (a rare lead vanadate–arsenate), both of which crystallize inside the porous structure of the slag. These minerals typically occur as microscopic crystals best observed under a stereomicroscope or SEM. The Laurion slags are among the most famous occurrences of these minerals worldwide, especially within the context of technogenic mineralogy.
