Coal ball Simple English Wikipedia, the free encyclopedia

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. Because of that ...

Calcified fossils are also known. The best examples are, however, the coal balls. Goal balls (Figs. 504 505) are irregularly rounded masses ranging in diameter from a few millimetres to a metre. These occur often in great numbers within chunks of coal. Each ball is a mass of calcium and magnesium carbonate with, sometimes, iron sulphide.

In the coal ball described were portions of plants that have hitherto been known from the Carboniferous of America only as impressions; they are Calamites, Sphenophyllum, Bothrodendron, and Lyginopteris. Only transverse sections of the steles of Calamites, Sphenophyllum, and Lyginopteris were found. Belonging to Bothrodendron are transverse sections of a stem tip, a megasporangium and ...

1. 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 ...

The exceptional preservation of plant fossils falls into two categories: whole plant preservation and anatomical detail. Whole plant preservation is controlled primarily by transport and event preservation (, ash falls), whereas anatomical preservation can occur through one of several taphonomic pathways: compressionimpression, silicification, coalball formation, pyritization, and ...

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.

Concept of Paloebotany: Palaeobotany or the study of fossil plants,, the plants existed in the past and now are entirely extinct. This is the difficult branch of Botany in respect that the fossil plants are difficult to obtain and they are rather scarce. Whenever the fossil plants are found, they are in parts which are to be coordinated.

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.
