"Coal balls perfectly preserve a window into what plants used to be like 300 million years ago.'' The plant life of that age would have resembled alien forests today, Punyasena said. Today's sporebearing plants are tiny, such as ferns, but back then they were as large as trees. The plants and surrounding environment are preserved in ...
The department of paleobotany, micropaleontology and mineralogy oversees the: 1) Collection of Micropaleontology and Paleobotany, containing over 45,000 macrofossils most identifiable to genus or species and over 50,000 palynological slides and residues; 2) Coal Ball Collection, containing over 18,500 coal ball peels (free and mounted on microscope slides) and over 5,000 kg of cut and
Identification and Description[iv] Daldinia concentrica is a relatively easy to identify mushroom that resembles hard, roundish lumps of coal stuck to the surface of decaying deadwood. Furthermore, unlike most other mushrooms, D. concentrica does not possess a cap, gills, pores, or even a stem. Instead, this species has a fruitbody composed of ...
A coal ball is a type of concretion, varying in shape from an imperfect sphere to a flatlying, irregular slab. Coal balls were formed in Carboniferous Period swamps and mires, when peat was prevented from being turned into coal by the high amount of calcite surrounding the peat; the calcite caused it to be turned into stone instead.
Mine index 0834 is the same mine in Kankakee County, mine index 0675 is the same in Grundy County, and in Will County, the mine index is 0359. Kankakee. 31N 9E. SW NW SE. Tipple Mining occurred in Kankakee, Will and Grundy Counties. This mine is atypical in having separate index numbers in the different counties.
Benson worked on coal balls, but it was instead to James Lomax, based in nearby Bolton, that Stopes initially turned for a collaborator. Although primarily a businessman (Howell 2005), Lomax had ...
COAL BALLS. Coal balls can be considered concretions, as they are rounded masses of a mineral different from the surrounding rock and deposited before consolidation of the host rock, which is coal. The compost of Coal Age forests settled in the swamps, and calcium carbonate infiltrated masses of matted vegetation, forming the coal balls.

Coal balls often form in acidic peats, or when seawater permeates the compressed plant matter. The carbonate forms a hardened ball that resists compression throughout burial, thereby preserving the plant remains in exceptional detail; even cellular details can be retained. Such structures can be studied using a range of techniques.
These coal balls are calcium carbonate concretions that formed in situ in some Carboniferous peats that structurally preserve the 3dimensional anatomy of the plant material present in the peat ...
Coal balls are permineralized peat, mainly found in Upper of Europe and North America but also in some Chinese Permian coals. Coal balls are predominantly calcium carbonate which has precipitated in the cell lumina and spaces between the plants within a peat formed in a mire ( Scott and Rex, 1985 ). Formation
Coal balls (exceptionally preserved calcareous permineralized peat), widely described from tropical Carboniferous Euramerian coal seams, have yielded diverse data on the biology, ontogeny and ecology of swamp plants and ecosystems. Probably over 75% of the swamp taxa may have been preserved, in contrast to probably less then 10% in other ...

Introduction. Coal balls were best defined by Seward (1895, p. 85). "In the Coal Measures of England, especially in the neighbourhood of Halifax in Yorkshire, and in South Lancashire, the seams of coal occasionally contain calcareous nodules varying in size from a nut to a man's head, and consisting of about 70% of carbonate of calcium and magnesium, and 30% oxide of iron, sulphide of iron, etc.
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.
Coal balls may be concretionary as there name implies, but more commonly are irregular masses complexly interfingering with the surrounding coal. Coal balls may be inches to many feet in diameter and height, so will commonly look like a limestone bed in a narrow core. Coal balls tend to be brown in color and the coalball limestone includes ...

Coal balls represent early, peatstage mineralization somewhat analogous to concretions in shale (, Phillips et al., 1976). Although a nuisance for mining, coal balls from these two seams can preserve peatforming plant structures to the cellular level and have been very important in reconstructing Desmoinesian plant biology and ecology ...
Coalballs are nodulelike rocks native to coal seams that contain mineralized plant organs or tissues (Zodrow et al., 1996), and are used for studies on coalforming plant species, structural morphology, and coalforming environments (Hilton et al., 2001, Wang et al., 2002, Zhou et al., 2004 ).
of coal balls selected from Stopes and Watson's study and a single analysis for an American coal ball presented by Darrah. Perhaps the most significant point is the great variation in the percentages of carbonates, pyrites and organic matter, and these published analyses by no means give the extremes. I have seen coal balls
Coal balls are carbonate concretions that preserve peat in cellular detail. Despite their importance to paleobotany, the salinity of coalball peat remains controversial. Pennsylvanian coal...
Definition. Coal balls are permineralized peat, mainly found in Upper of Europe and North America but also in some Chinese Permian coals. Coal balls are predominantly calcium carbonate which has precipitated in the cell lumina and spaces between the plants within a peat formed in a mire ( Scott and Rex, 1985 ).
Thin coal rims or streaks on the outside of some fossils represent all that is left of the original plant tissue. Permineralized Calamites which include original plant details are preserved in rare deposits called coal balls, but these are usually only found in active coal mines, so are not found by collectors.
The split coal balls are initially studied for petrography and it was observed that the quartz grains in the coal balls are small (< silt size) and below the resolution capabilities of a standard Petrological microscope though on rotation of the stage under crossed nicols, at places shows mild undulose extinction of micro quartz grain (Fig. 4 ...

Coal balls floras from the Taiyuan Formation in north China have been mainly studied by Tian Baolin and collaborators, from the no. 7 coal seam in the Xishan coal field and have been summarised by Li et al., 1995, Tian et al., 1996. From these works quantitative studies have been undertaken, compiled from hundreds of coal balls (Wang et al., 1995).
Balls Head Reserve facing Berrys Bay and McMahons Point. The Reserve was named after Henry Lidgbird Ball, a Royal Naval officer and commander of one of the ships that were part of the First Fleet that arrived in Botany Bay in 1788.. Before the arrival of white settlement, the Cammeraygal people lived in this part of New South Wales. Middens, art sites, and rock engravings are still present in ...
Coal balls are petrified pockets of plant debris that were preserved 280 million to 325 million years ago during the Upper Carboniferous Period, sometimes called the Great Coal Age. Plants immortalized in these coal balls are preserved at the cellular level, details not preserved in other types of fossils.

coal ball: [noun] a nodule found in coal usually composed of calcite or silica and carbonaceous matter and having fragmentary or microscopic plant remains.
Directions. Mix crushed Oreo cookies and cream cheese in a large bowl until well blended. Use your hands to shape mixture into 48 (1inch) balls; place on a tray and freeze until thoroughly chilled, about 10 minutes. Line a shallow pan with waxed paper. Dip Oreo balls in melted chocolate; place in a single layer on the prepared pan.
Definition and formation: Coal balls are calcareous masses of fossil peat found in coal beds. They are formed in the original peat before it undergoes coalification (DeMaris and others, 1983; Scott and others, 1996).
The meaning of COAL BALL is a nodule found in coal usually composed of calcite or silica and carbonaceous matter and having fragmentary or microscopic plant remains.
