• Description:
  Samples of lignite from thin, tabular seams ranging from a few centimeters to almost 3 meters in thickness in Kemper and Lauderdale Counties, MS, were studied by proximate, petrographic, mineralogical, and grain size analyses. Proximate analysis of the samples indicates high moisture (30%), ash (63%), and volatile matter (21%), and low fixed carbon (12%) values. Grain size and mineralogical analyses indicate a predominance of sand-size quartz in the lignite. Petrographic analysis indicates that humodetrinite (37%) and gelinite (27%) are the major organic constituent particles. The inertinite macerals (19%), fusinite and semifusinite, are unusually high in these low-grade coal seams. The cellular macerals, textinite and ulminite, compose only 11%, and corpohuminite and exinite compose 5% of the lignite samples studied. The values from these analyses seem to indicate that the lignite was deposited in a deltaic environment influenced by fluvial and marine processes. The paleo-environment was dominated by herbaceous plants and wood from angiosperms and lacked significant amounts of conifers in the depositional area. [Description provided by NIOSH]
