    Abstract. Graphite, as a pure form of carbon, is found in Sri Lanka as disseminated flakes and in veins. In veins found in high grade metamorphic rocks, graphite often attains 99% purity. A variety of metals are found to accumulate in the graphite, mainly at the margin of these veins. Gold, in particular, becomes concentrated at vein margins
