Storisens transport av kisblokker fra Joma.

Abstract

For three summers the Geological Survey of Norway has carried out a special hunt of pyrite boulders within the Grong area and adjacent districts. One result is the establishement of a marked boulder train from the Joma pyrite deposit to the coast, a distance of close to 90 km, see fig. 1. In all about 230 boulders have been found, most of which have been plotted on fig. 1.
