1792: Academician Ozeretskovsky's expedition to the "black earth" of Lake Onega

Eighty-seven years before Inostrantsev would formally name shungite, another Russian academician walked the same Karelian shore and wrote down what he found. Worth knowing if you read older Russian sources.

Nikolay Ozeretskovsky (1750–1827)

Nikolay Yakovlevich Ozeretskovsky (Николай Яковлевич Озерецковский) was a Russian naturalist, ethnographer, and academician of the Imperial Russian Academy of Sciences. He was one of the prolific scientific travellers of the late 18th-century Russian Enlightenment, the era when the Empire was systematically catalogued by expeditions of academy-sponsored naturalists.

Ozeretskovsky's expedition to the Olonets region in 1785 produced the book Travels around Lake Ladoga and Lake Onega (Путешествие по озерам Ладожскому и Онежскому), published in St Petersburg in 1792.

The "black earth" entry

In that book, Ozeretskovsky described the dark carbon-rich rocks around the northern shores of Lake Onega. He called them "черная олонецкая земля", "black Olonets earth", and noted their resemblance to coal but their distinct properties. He observed local people using them for various purposes including water-related practices.

Ozeretskovsky's interpretation was that the rock was a form of coal deposit, which is geologically incorrect (coal didn't exist 2 billion years ago when shungite formed) but reasonable given the state of geological knowledge in the 1790s. The point is: he saw the rock, recognised it as anomalous, and put it on the formal scientific record nearly a century before Inostrantsev formally named it.

His other contributions

Ozeretskovsky's broader work on Russian Karelia also included:

- Detailed ethnographic observations of Karelian and Russian rural life.
- Descriptions of the Marcial Waters spa as it operated 70+ years after Peter's death, by Ozeretskovsky's time, the resort had passed through various periods of activity and decline.
- Geological observations on the Lake Ladoga and Onega basins that founded the descriptive geology of the region.

Why this matters

The shungite history did not start with Peter the Great in 1719 or with Inostrantsev's 1879 naming. It runs in continuous documentary record from at least 1375 (the Chelmuzhsky charter mentioning Shunga village), through the 17th-century Marfa Romanova exile tradition, through Peter's 18th-century imperial intervention, through Ozeretskovsky's 1792 academic description, to Inostrantsev's 1879 formal classification, to the 1992 fullerene detection, to today.

That's six and a half centuries of documented Russian engagement with the same rock at the same site. Few minerals have anywhere near that depth of historical record.

Editor's note (2026 audit): Thread says Ozeretskovsky used 'черная олонецкая земля' but verbatim quotes in thread 186 cite him using 'аспид' and 'каменное уголье'. Thread 235 attributes 'чёрная олонецкая земля' to Komarov 1841/1848. Suggested edit: Reconcile naming chain: Ozeretskovsky 1792 used 'аспид' / 'каменное уголье' / 'углистый сланец'; Komarov supplied 'чёрная олонецкая земля'.
