Abstract
Spectrographic analyses for 15 elements of 249 block samples of coal are reported here. These samples represent 28 localities of beds 5 and 6 of Illinois and their correlatives in Indiana and western Kentucky.
Comparison with the coals of the Northern Great Plains province shows a similarity in the total amount of these elements in the coal, however, individual elements differ considerably. The degree of association with the organic or inorganic matter of coal is determined by the separation of thirteen samples into float and sink fractions. Be, B, Ti, V, Ga, and Ge are essentially associated with the organic matter of coal. Zn, Sn and La are invariably found to be associated with the inorganic matter. Cr, Co, Ni, Cu, Mo and Y have intermediate degrees of association.
