dc.description.abstractA Precambrian granite pegmatit formerly mined for feldspar is situated at Spro, Nesodden, 20 km SSW of Oslo, Norway. It is shown to consist of two different phases. The paragenesis seems to be as follows: 1) Older phase, characteristic minerals: microcline, muscovite, monazite, thorite, samarskite, columbite, beryl(?). 2) Younger phase, characteristic minerals: fine-grained albite, green muscovite, tourmaline, topaz, microlite, apatite, calcite, fluorite.
