| Abstract: | The inorganic content of Okefenokee peat, in the absence of a significant detrital contribution, is a function of sponge spicule, phytolith, and diatom abundance in addition to the degree of organic matter decomposition and the frequency of fires. The detrital component (quartz) dominates ash composition where it is present.No clear correlation has been observed between the inorganic content of coals examined in this study and their maceral composition. Vitrinite-rich coals have a wide range of ash yield. These observations suggest that the minerals have been introduced detritally rather than accumulated as a result of peat degradation. Quartz in the coals appears to be detrital, and the presence of 2m1 mica indicates that there is also a detrital contribution to the clay minerals present. |
