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