| Abstract: | The study of coal succession from bore hole No. Q-448 of Yellendu area of the Godavari valley coalfield, Andhra Pradesh reveals
that the coals of Queen seam are high volatile bituminous C in rank and have vitrinite reflectance (Ro max %) varying between of 0.52 and 0.62%. The petrographic constitution however, suggests that the depositional site appears
to be a slowly sinking and tectonically controlled basin, having received continuous supply of vegetal matter rich resource
at regular intervals. The formation of inertinite rich coal suggests, oxidising enviornment of deposition. The dominence of
vitrinite and liptinite constituents in these coals postulates the existence of alternating cold and humid spells. The present
study indicates that these coals originated under an alternate oxic and anoxic moor condition. |
