Hidra (formerly Hitterö) is an island on the southwestern coast of Norway. In the eastern part of the island, around the small RasvÄg bay, several granite pegmatite dikes have been quarried for feldspar. Quarrying started around 1870 and ended around 1906-1910. One exception is the IgletjÞdn quarry which was quarried until around 1930.
Xenotime-(Y) (Berzelius, 1824, under the name Phosporsyrad Ytterjord, Beudant 1832 under the name Xenotime), Kainosite-(Y) (Nordenskiöld, 1886), Polycrase-(Y) (Scheerer, 1844) and Aeschynite-(Y) (Brögger, 1906, under the name blomstrandine), were first described from pegmatites in this area. The pegmatites are also especially known for having produced large crystals of Gadolinite-(Y).
There is also a two pyroxene-bearing granulite containing ferrosilite.

Type Locality: Urstad Feldspar Mine, Hidra, Flekkefjord, Agder, Norway Habit: Platy after {010}, with the dominant form {010}, {130}, {001}. Forms also observed: {110}, {120}, {111}, {101}, [001} Colour: Brownish black, metamict with thin brownish alteration Description: BrĂžgger (1879) gave a crystallographic description of a black mineral from Urstad without chemical analysis. He thought it to be identical with aeschynite (From Miask, which later was named aeschynite-(Ce)). In BrĂžgger (1906) the mineral were described in detail, and gave it the name Blomstrandine. He states on p. 104 the that aeschynite from Miask is a Cerium-Aeschynit and that the blomstrandine from Hitterö was a "Yttrium-Aeschynit".

Geochronology
Mineralization age: Neoproterozoic : 911 ± 3 MaImportant note: This table is based only on rock and mineral ages recorded on mindat.org for this locality and is not necessarily a complete representation of the geochronology, but does give an indication of possible mineralization events relevant to this locality. As more age information is added this table may expand in the future. A break in the table simply indicates a lack of data entered here, not necessarily a break in the geologic sequence. Grey background entries are from different, related, localities.
