Previous petrographic and sulfur analyses of the collected interval samples showed that the coal bed could be divided into a basal low-sulfur lithotype, a middle high-sulfur bone lithotype and an upper high-sulfur lithotype. At one location a high-sulfur rider unit is present. In this study we have conducted detailed palynological analyses on all of the interval samples and ash geochemistry on the upper high-sulfur lithotype intervals and two of the basal high-sulfur basal lithotype intervals.&lt;/p&gt;&lt;p&gt;Geochemical analyses show that As and Pb are generally high in the high-sulfur upper lithotypes from all five sites. Carbonates, having associated high levels of Ba and Sr, are important in the ash geochemistry of the lower, low-sulfur lithotypes. Ga, Ge and W are enriched in the higher vitrinite lithotypes among the low-sulfur samples. The basal lithotype at each of two sites, which was analyzed in detail, is enriched in yttrium plus the lighter rare earth elements.&lt;/p&gt;&lt;p&gt;The basal low-sulfur lithotypes are dominated by arboreous lycopod spores. The middle, low-sulfur portion of the bed is dominated by herbaceous lycopsids (&lt;i&gt;Densosporites&lt;/i&gt;) at the base of the unit and becomes increasingly enriched in&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Lycospora&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;towards the top of the unit indicating that the peat-forming environment became wetter. The greatest arboreous lycopod spore abundances in the upper, high-sulfur portion the bed, along with an overlying marine roof, indicates that peat deposition was terminated by a marine inundation.&lt;/p&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div id="preview-section-introduction"&gt;&lt;br&gt;&lt;/div&gt;&lt;div id="preview-section-snippets"&gt;&lt;br&gt;&lt;/div&gt;&lt;div id="preview-section-references"&gt;&lt;br&gt;&lt;/div&gt;</dc:description>
