Nearly three-quarters of exploration projects are located in such tectonic units. In contrast to metallic raw materials, orogens are poor in graphite deposits. 5.2 In terms of regional aspects 5.2.1 by continents Table 5 - Distribution of C-resources by continents in Mio t Continent CResourc es all Share in % CResources producing operations only Share in % CResources exploratio n projects only Share in % Asia 916.8 52.15 175.2 52.63 78.65 11.58 Africa 544.0 30.94 134.3 40.34 407.57 60.02 Oceania 82.8 4.71 0 0 82.06 12.08 North 118.8 6.76 4.1 1.23 56.99 8.39
