In attempting to analyze the depositional environment for the Kentucky No. 12 Coal three columns were sampled from a 1 km area. The columns yielded 76 miospore species belonging to 33 genera, and representing in decreasing order of abundance, arborescent lycopods, tree ferns, calamites, small ferns, gymnospermous trees, seed ferns, herbaceous lycopods, and others from unknown origin.
The pattern of spore distribution in the columns did not appear to be affected by the presence of several partings, a feature which calls into question several mechanisms proposed for the origin of partings and also creates difficulties for an autochthonous origin for this coal. The allochthonous model proposed by Austin appears to have merit in what it does propose but leaves several important questions unanswered.
Efforts to find a correlation between lithotype and spore assemblages within this coal were unsuccessful.
As expected, the correlation between columns was affected by distance but even at 1 km distance the columns could be correlated using overall spore distribution.
