Brandon lignite

Aureal Cross I really cannot believe that the type of cell-wall alteration seen by Dr. Spackman in the Brandon lignite resulted from microbial attack. 

Codification of Woody Tissue as Deduced From a Petrographic Study of Brandon Lignite... 

The vitrinitic substances found in coal seams are commonly asserted to be derived from wood or woody tissue. The statement is usually made without any intention of being specific about what is meant by w ood and, in fact, several non-wood tissues are often included intentionally in this broad generalization. It is generally agreed that various different substances are contained in these woody source materials and that several different biochemical, chemical, and physical processes may influence their alteration. In spite of this, our coal research has led many individuals to think of the vitrinites as forming a single maceral series. The coalified w oods in the Brandon lignite...

Peter A. Hacquebard The differentiation of various vitrinic compounds so beautifully shown in the Brandon lignite—e.g., between cell wall material and cell-content material, can also be observed in bituminous coals. I have been able to show this on polished sections by using an etching technique. How has Dr. Spackman shown this in thin sections, and what would be the effect of rank increase on the existence of these two types of vitrinite—i.e., types derived from cell walls and cell contents ...
