EEN 'EXOTISCHE' VUURSTENEN BIJL UIT GLIMMEN (GR.)
Since the middle of the 1980s the prehistoric 'import' in the northern Netherlands of lithic artefacts made of 'exotic' raw materiais has been the subject of a research project. Several flint types have by now been identified; the results were published mainly in the Nieuwe Drentse Volksalmanak. There were two types ariginating from the isle of Helgoland, as well as artefacts that were produced at the Lousberg outcrop, in the Rijckholt region, at le Grand-Pressigny and in the Paris Basin (Tertiary flint). in the present artide we describe a polished axe made of yet another type, the so-called Simpelveld flint. The axe was found near Glimmen in the province of Groningen and so far is the only specimen known from the northern Netherlands. Simpelveld flint, with its characteristic lamination, was quarried in the southeastern part of the Dutch province of Limburg.
