The evaluation of organic material in the coal balls was based on peel studies from 50 randomly selected coal balls from all areas of the crop. Each coal ball regardless of size was considered as one unit. From many of the coal balls numerous peels were obtained but only 2 peels oriented normally to each other were evaluated from each concretion.
COAL BALL PEEL TECHNIQUE. Coal balls are spherical to ellipsoidal masses of calcium carbonate (or calcium magnesium carbonate) in which plant tissues are tree dimensionally preserved, embedded within the carbonate matrix. The carbonate essentially impregnates the residues of the plant cell walls and fills the cell cavities. Concentration of the carbonate occurred by localized precipitation ...
To date, U of I researchers throughout the decades have created more than 250,000 coal ball peels. Part of Lakeram's work is digitizing highmagnification images of them. "The point of digitizing the peels is (to) eventually create an artificial intelligence to automate the identification of the plant contents within these balls," he said.
activities, such as analyzing a coal ball peel to research the geological and biological past (a common scientific practice); exploring the process of converting coal to electricity using an interactive dragndrop interface; and comparing alternative methods of electricity production, among others (Figure 3). It is worth noting that socially
This embeds the cells preserved in the coal ball into the cellulose acetate. Upon drying, the cellulose acetate can be removed from the coal ball with a razor and the obtained peel can be stained with a lowacidity stain and observed under a microscope. Up to 50 peels can be extracted from 2 millimetres ( in) of coal ball with this method.

A coal ball is a type of concretion that is found in coal seams and consists of plant debris (peat), which has been permineralised by calcite. Coal balls vary in shape from imperfectly spherical to flatlying, irregular slabs. ... who cut and peel the coal balls to research the geological past. ...
the cellulose acetate peel method and coal ball curation. We also introduce a new protocol for the digitization and curation of peels, which is in use at the Phillips Coal Ball Collection at the University of Illinois Urbana‐Champaign. In documenting these protocols, we hope to establish a standardized procedure for working with coal balls.
Coal balls, in which fossil plants are preserved in permineralized peat deposits, have widely been described from coal deposits representing the tropical forest of the Carboniferous. Coal ball prepar...
Plate 10"Coal ball" peel. The woody plant material is preserved in calcite and can be seen distinctly. Black material is coal (Mineral coal, X 16). An Acrobat PDF version of this plate is available. PyritePyrite is widely distributed throughout the coal beds and is occasionally associated with marcasite. It occurs principally as ...

Coal ball. A Coal ball is a permineralised life form that is full of calcium, magnesium and occasionally iron sulfide. They generally have a round shape. Coal balls are not made of coal, even though they have the name "coal ball". In 1855, two English scientists, Joseph Dalton Hooker and Edward William Binney, found coal balls in England.
These "peels" are studied closely by scientists. It's a process that Tom Phillips created and others have developed. To date, U of I researchers throughout the decades have created more than 250,000 coal ball peels. Part of Lakeram's work is digitizing highmagnification images of them. "The point of digitizing the peels is (to ...

Upon drying the acetate film was removed (peeled—hence the reference to the "peel technique") to provide a thin section of the coalball plant material. A 1 cm 2 grid of clear cellulose acetate was attached to each coalball peel. Within each square centimeter, the most common plant part and its taxonomic affinity were identified and ...

Overview of the warehouse collection of coalball peels assembled by Tom Phillips and students. Dr. Phillips, as he was ever known to most of his students, turned his attention almost exclusively to research on Pennsylvanianage plants, anatomically preserved in coalballs, starting in the early 1970s.
