Sometimes, presence of coal ball in the roof of a coal seam is considered as a marker horizon. Growth of dolomite may be influenced by marine invasion. In course of coalification, calcite and ankarite may develop along cracks and fissures. At around 900 °C calcite changes to lime while dolomite alters to lime as well as periclase.
Department of Botany, Ohio State University, Columbus, Ohio 43210 ABSTRACT ... Eggert, 1969), only two coalball occurrences from the Appalachian Basin are noted in the literature (Schopf, 1961; Cross, 1967). To our knowledge, no coalball occurrence have been reported in the state of Ohio, but recent inquiries have
Examination of Iowa coal balls from the Des Moines Series has yielded two petrified stern fragments assignable to the arborescent lycopod genus Lepidophloios. ... Department of Botany, The University of Iowa, Iowa City, Iowa 52240 among species of Lepidophloios are reexamined. In . particular, the
normal coalball samples were relatively depleted in 13C (20 to 23 permil rel. PDB). This evidence indicated that isotopicallyenriched marine, inorganic carbon was an important source of carbonate in faunaltype coal balls and that isotopicallydepleted carbon from plant decomposition was the major source of carbonate in normal coal balls.

In coal balls where Calamites plant parts are permineralized (original structures replaced by minerals) plant parts sometimes have different names to show that they preserve internal anatomical structures. Some even show cellular structures (Stewart, 1981; Cichan and Taylor, 1983)! ... Studies in fossil botany,, Pteridophyta: A C Black ...

The physical and digital curation of cellulose acetate peels and other types of coal ball specimens is critical for longterm preservation and accessibility. Physical curation involves embedding coal balls in media to slow pyrite deterioration. Digital curation creates highresolution scans of peels, which can be shared and accessed online.

Coal Balls. Because coal balls are accumulations of (degrading) plant material (technically peat), they also are an excellent source of various forms of decaying organisms, including fungi. Numerous fungal remains have been found in coal balls, including hyphae, spores, and various types of reproductive structures.
1. A morphological study was made of plant material preserved in coal balls from Calhoun coal mine, Richland County, Illinois. The geologic horizon is Middle Conemaugh, early Upper Pennsylvanian. 2. Preparations were made by the cellulose peel method. 3. Seven plants are described in detail. Of these, four are sporangia of ferns, one is the microsporangium of a pteridosperm, and two are seeds ...

The lab had two hoods, specialized microscope rooms, desk space for students and postdocs, and cabinets ...
Acetate paper with a thickness of inches is used to make the first peel of a coal ball after it has been cut with a rock saw. This paper type can also be used for test peels to identify the optimum etching time in acid. The .005inchthick acetate paper is more robust, reducing the chance of damage when removed.

coal ball, a lump of petrified plant matter, frequently spheroid, found in coal seams of the Upper Carboniferous Period (from 325,000,000 to 280,000,000 years ago). Coal balls are important sources of fossil information relating to the forests preceding the Coal Age. As a result of a variety of conditions, small pockets of plant debris in Carboniferous swamps, infiltrated by mineral salts ...

Department of Botany, Ohio University, Athens, Ohio 45701 Basal parts of Botryopterisforensis have been discovered rooted within the mantle of the tree fern Psaronius. Specimens occur in Upper Pennsylvanian coal balls from near Steubenville, Ohio, USA. The Botryopteris stems branch profusely, and these shoots are intertwined with the
6. Coal Balls: Petrifactions of spherical specimens are generally termed coal balls. During the formation of coal balls the plant material in swamps gets infiltrated with carbonates of calcium or magnesium, so that the debris of plants will not get converted into coal. Coal ball plants are of great value in palaeobotanical studies. 7.
