When acetate peels are prepared from cut coalball slices, dissolved acetate infiltrates microvoids created by acid etching. When a peel is lifted from a coal ball slice, coalified plant remains are wellembedded in the dried acetate film. Coalball carbonate minerals are partially embedded in a similar manner, in particular, the fibrous ...

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 ...

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.
