AB This paper focuses on the similarities and differences between metamorphicgraphite (formed in situ from organic matter) and fluid-deposited graphite.We discuss the formation of fluid-deposited graphite in terms of the source ofcarbon, the characteristics of the C-bearing fluids (the C-O-H system), the mechanismsof carbon mobilization, and the mechanisms of carbon precipitation. Newand existing analytical data are compiled on the physical and chemical characteristicsof fluid-deposited graphite olitained by the following techniques: opticalmicroscopy, differential ilierrilal analysis, thermogravimetry, X-ray diffraction, Ramanspectroscopy, and stable isotope mass spectrometry. Our discussions focuson major, that is, volumetrically significant, worldwide concentrations of graphite
