contains no trace elements, but is a common trace mineral in coal of detrital
origin and is generally closely associated with other detrital minerals,
as in the SEM photomicrograph shown here (dots
at the bottom of the photograph are each 10 µm apart). Submicron
rutile grains mainly occur within clay mineral partings, but may also be
present in minor amounts throughout generally low mineral matter coals
where they are likely windblown in origin. Here 1-2 µm rutile
grains are shown within clay minerals, mainly illite, containing a chalcopyrite
crystal and small fragmented organic coal particles.
