Metabasites were absolutely prevalent raw materials for polished stone tools connected with the Linear Pottery culture (Linearbandkeramik, LBK) in Central Europe. Besides the key source of amphibole-rich metabasites in the Jizerské hory Mts. we already know a few other natural outcrops with their prehistoric using in the Bohemian Massif and some other can be supposed. In the article we have compared LBK polished tools from two different areas in the Czech Republic: the Bohemian-Moravian borderlands and Upper Odra River basin. In spite of natural occurrences of metabasites near the both areas, all studied polished tools have been made of the amphibole-rich metabasites from Jizerské hory Mts. It accentuates importance of the unique Neolithic mining field in the Jizerské hory Mts.
