Although the third and final segment of the antennular peduncle was usually present, the basi cerite was rarely added and the statocyst never found among stage IVB animals.
For a long time it was the only known locality for cerite. It is also the type locality for allanite-(Ce), bastnasite-(Ce), cerite-(Ce), lanthanite-(Ce), tornebohmite-(Ce) and linnaeite, as well as for the elements cerium and lanthanum.
of cerite, are rather widespread in public and private collection in Europe, and the collection of the Naturhistoriska Riksmuseet (Swedish Museum of Natural History) in Stockholm contains a large suite of Bastnas specimens, including the type specimen of tornebohmite.
The mine was named Ceritgruvan because it contained large amounts of cerite. Around 1848, small amounts of cerium ore (mainly cerite) were taken from the mine and from the old dumps.
Cerite and allanite had already been noted in the mid-18th century by Cronstedt, but it is not known whether Sankt Goransgruvan was ever mined specifically for cerium ore.
During 1937-1938 several crates of extracted cerite ore were exported to Norway, and the dumps were again hand-picked in the late 1940's, but the material was never sold and was later dumped in a nearby mine (Hogrelius, personal communication, 1994).
In 1750 Cronstedt reported a "dense, reddish, rather heavy ironstone" and also described a "black wolfram" containing iron (Tidestrom, 1890); this is probably the first note on the cerite and allanite from Bastnas.
