Ogorodnyi

Associated with the Imandra-Varzugskii fault the Ogorodnyi peralkaline granite occurrence is a northwest-trending, elongate body of 5 km2. The rocks are characterised by gneissose textures which are particularly well developed at the margins. The principal minerals are microcline, albite, quartz, ferrohastingsite and variable amounts of aegirine-augite and biotite; accessory are magnetite, titanite, orthite, epidote, apatite, fluorite, garnet, hematite and sulphides. The massif is cut by amazonite-bearing pegmatites and quartz veins.
