Pegmatite.
Tantalum was discovered in ore from Kimito (and Ytterby, Sweden).

I recently had some discussion with Prof. Jim Marshall, Fellow, American Chemical Society, on the location and proper spelling of this locality, due to the fact that I have posted an image of tapiolite from Skogsböle. Dr. Marshall, with his wife Jenny, is coauthor of "Rediscovery of the Elements", a book about their journeys to the discovery locations of the elements.
In any case, here is some communications, via Lahti Seppo of the Finnish Geological Survey, stating that
The Nb-Ta mineral samples studied by Ekeberg were discovered from the quarries at Skogsböle (village), Kemiö - Note Skogsböle with two s! There is also another village Skogböle (with one s) in Kemiö - Skogböle far north - but this is wrong location. Nowadays Kemiö (or nowadays the commune is called Kemiönsaari - Kemiö Island) is an active feldspar mining area in Finland. The old Skogsböle quarry does not exists any more - a new quarry occupies its position. Lesson 1 now in Swedish: böle means a village and skog is forest in English; skogs is a genetive form of skog!


Further, Dr. Marshall found that
The passage from Nordenskiöld was from Nils Gustaf Nordenskiöld, J. Chem. Phys. 1821, 31, 367-380. Journal für Chemie und Physik was also known as Scweigger's Journal. "Last night I had a flash and recalling the original article by Nordenskiöld in 1821, which says the estate of Skogböle was 3/4 mile from the Kimito Church (which I thought was impossible because the Kimito Church, dating from 1200, was FAR from the Baltic Ocean, which was supposedly near the mine), it suddenly hit me that perhaps in 1821 the Swedish mile was different from the English mile. To make a long story short, before the metric system was adopted in Scandinavia, a Swedish mile was 26,000 feet! (= 10.7 km). Well, 3/4(10 km) = 8 km west of Kimito sits just right on top of Skogsböle (note the extra "s"). Voila! The spelling confusion was due to Nordenskiöld changing the original spelling from Skogsböle to Skogböle (reason unknown)."

A map from Lahti Seppo is included, look under the photos tab, showing the location of the old quarry, its coordinates (easily determined from Google Earth) are 60.143104 22.599734.
