Mineralogy of selected lignitic coal overburdens of the Wilcox group in east Texas

, : Mineralogy of selected lignitic coal overburdens of the Wilcox group in east Texas. Soil Science 137(4): 207-215

Lignite overburden core samples obtained in the premining stage were size-fractionated and analyzed by X-ray diffraction and chemical methods to determine their mineralogical composition. Although a broad similarity was observed in crystalline mineral assemblage in these fluvial sediments from east Texas, wide variations were also observed in the distribution of smectite, kaolinite, mica, vermiculite and chlorite, with sample location and depth. EM investigations indicated that localized concentrations of siderite were probably authigenic in origin. The physicochemical properties and mineralogical composition data obtained in these investigations suggest that segregation of existing low-fertility surface soils for top-dressing may be unnecessary, provided that pyrite-rich spoil material and clayey substrata are not deposited in the upper soil zone.
