Ås Brygga at Alnön- a classic locality one would believe. That is completely wrong- Ås Brygga is manmade and thus it is an anthroposophic locality!
The pier itself (Brygga) was made with rocks mainly from the 2 iron mines some hundred meters away and consist of titaniferous magnetite, apatite, serpentine and biotite, plus of course other good construction material. It was built in order to ship ore to the local blast-furnaces (eg Galtström).
The ores were found already in 1670- but mining started not earlier than 1762 when 860 kgs of ore were mined. 1879 production was 800 tons and 1884 the last year before closure: 150 tons.
Even though the ore was mixed with ”imported” ore from the mines at Utö (http://www.mindat.org/loc-3194.html) it was not possible to get any good results due to the high titanium content (10-15 % as TiO2 ). The main shaft at Stavsätt was less than 20 meters.
But, once again the deposit became interesting during WWII when som trenching and sampling was done.(Eckermann (1948= SGU ser Ca 36, Lundqvist et al SGU ser Ba31 (1990))
