Figure 11.4.7. Triterpane fingerprints (GC/MS
191) of coal and natural coal tars associated with coal fires in
the Breathitt Formation, Kentucky: (A) high-volatile bituminous coal from the Breathitt Formation contains
triterpanes with high proportions of NH, Tm, H, M, and homohopanes with higher proportions of
m
/
z
S
relative to
R
, (B) and (C) carbonized coal resembles the coal with lower proportions of NH relative to H and higher
proportions of BNH and M relative to H, and (D) and (E) coal tars collected at vents 1 and 5 closely resembled
the proximal carbonized coals.
