We describe several unusual forms of natural graphite from an alkaline pegmatite that cross-cuts rischorrite in the Hackman Valley, Khibiny Massif, Kola Peninsula, Russia. The graphite occurs macroscopically in two forms: as spherical aggregates up to 2 cm in diameter of friable, radially aligned fi...
