Europe's heavy-mineral sands, by the record
What European geological surveys, an EU-funded seabed database and a handful of studies document about heavy-mineral sands in Europe, country by country, and where that record runs out.
Reviewed by Peter Uppal
The short version
The GeoERA MINDeSEA marine placer database, a pan-European compilation of existing and accessible data last updated in October 2021, lists 89 placer occurrences in 12 marine regions and 14 countries. National surveys and individual studies add occurrences in Poland, Greece, Spain, Denmark, Iceland and Ukraine; the Polish survey says total resources have not been estimated beyond preliminary assessments, and the Greek review's authors say quantitative grade and tonnage estimates were not available to them. In the USGS Mineral Commodity Summaries 2026 production tables, Norway and Ukraine are the only European countries with separate titanium rows, and no European country has a separate zircon row.
One seabed database
The pan-European starting point is a project on seabed minerals. MINDeSEA's marine placer database, issued in October 2021, contains 89 occurrences in 12 marine regions and 14 countries, mapped at a scale of 1:250,000, which is regional-scale mapping. The countries are Albania, Bulgaria, Cyprus, Iceland, Spain, France, United Kingdom, Ireland, Italy, Latvia, Poland, Romania, Russia and Ukraine. The database covers placers of erosion-resistant minerals generally, not heavy-mineral sands alone: it compiles all existing and accessible data on marine placers in European waters, on minerals like gold, cassiterite, rutile, garnet, magnetite.
Its own documentation sets the limits. The EGDI metadata record describes the layer's purpose as compiling fragmented marine data products and metadata on areas explored and investigated for marine placer deposits. A companion MINDeSEA review, issued as a draft in July 2021, says current knowledge is sparse, mostly limited to seafloor deposits on shallow waters, and that knowledge of occurrence is limited by the extent of exploration carried out so far.
That review places the main exploitation areas offshore Australia, Africa and SE Asia, and its table of occurrences lists the Ukrainian Black Sea entries as not operating.
Country by country
Poland. The Polish Geological Institute's 2025 entry places Baltic heavy-mineral concentrations within the Ławica Odrzana and Ławica Słupska areas. At Ławica Odrzana, its shares of the total heavy minerals in the deposit are ilmenite 31%, zircon 5%, leucoxene 4%, rutile 4% and garnets 32%, with the remainder not itemised. At Ławica Odrzana, the PGI gives heavy-mineral content between the sea bottom and 0.5 m of between 1.4 and 21.7%, with an average given as 4.4–4.5%, and between 0.5 and 1.0 m of between 2 and 4.2%, with an average given as 2.5–3.3%, against an assumed qualifying parameter of 2% heavy minerals in the sands. The institute says total heavy minerals resources have not been estimated, but according to preliminary assessments a tonne of sand holds, in the institute's words, "about 17.40 kg of ilmenite, 2.5-3.5 kg of zirconium, rutile and monazite, and 9.5-30.0 kg of garnets". The PGI describes Ławica Słupska as holding prospective resources of sands with heavy minerals.
Greece. A 2019 review in Minerals describes coastal heavy-mineral sands at sites including Kavala (west of the city), the island of Samothrace and the Sithonia peninsula, with allanite named as the main REE-hosting phase in the Kavala sands. At Aggelochori, ilmenite, magnetite, garnet, zircon and rutile are the main mineral constituents. The 2019 review's authors write that Greece "appears to be a promising candidate to become a leading EU country" for rare earths, and that "quantitative grade and tonnage estimates for these occurrences were unfortunately not available to us".
Spain. A 2025 conference paper on the Vigo estuary in Galicia reports great potential of placer minerals on the Santa Marta and Vao beaches, with garnet, ilmenite, zircon, monazite and, locally, xenotime. It found greater placer accumulation on the beaches than in the estuary's shallow-water areas.
Denmark. A 1960 study by the Geological Survey of Denmark found that most of the large deposits were in northern and western Jutland. It named magnetite, ilmenite (containing haematite), and zircon as minerals assumed to be of economic importance, and said garnet may prove useful as a by-product of extraction.
Greenland and Iceland. A 2023 titanium overview by the Finnish and Norwegian geological surveys lists heavy-mineral sands in Greenland and Iceland among its deposit types, with minor potential for onshore and offshore heavy-mineral sands derived from gabbro intrusions in the Lón district of south-east Iceland.
The pan-European review's own word for what is known about marine placers is "sparse".
Where production is recorded
Ukraine. Among the sources cited here, only the 2014 USGS deposit model records production from European heavy-mineral sands, in Ukraine, from 2012. As of that publication, Velta LLC initiated production in 2012 from the Birzulivske heavy-mineral sands deposit in Kirovohrad oblast, and the Volchanske deposit in Dnipropetrovsk oblast extends for more than 20 km and is as wide as 1 km.
Norway, on this publication's reading, points to rock rather than sand. The USGS deposit model names anorthosite bodies as another source of titanium, represented by two mines, Lac Tio in Quebec, Canada, and Tellnes in Norway.
In the country rows of the MCS 2026 titanium mineral concentrates table, Norway and Ukraine are the only European countries listed separately, with estimated 2025 production of 390 thousand t of ilmenite for Norway, and 200 thousand t of ilmenite and 10 thousand t of rutile for Ukraine, in TiO₂ content; the table does not say from what kind of deposit. On this publication's reading, Norway's row reflects that hard-rock source rather than sands. In the country rows of the MCS 2026 zirconium mineral concentrates table, no European country is listed separately; any European output would fall within "other countries".
