Nov 01, 1999 Reports of siderite concretions with anatomically preserved plants from coal-seam splits are rare from the Carboniferous worldwide. Zaritski (1970, p.28) reported an example from the Donets Basin without supporting data, and the only other report is from the split in the Foord Seam for which Zodrow et al. (1996)gave some geochemical results, based on two unoriented concretions.
