Implications of Carbonate Petrology and Geochemistry for the Origin of Coal Balls from the Kalo Formation (Moscovian, Pennsylvanian) of Iowa
Coal balls are carbonate concretions formed in peat during the Pennsylvanian and early Permian. Microprobe and microscope analysis reveal that polycrystals of high-Mg calcite (HMC), which are also high in Sr, are the earliest calcium carbonate to form in the Williamson No. 3 coal balls from the Kalo...
