Title from cover. Includes bibliographic references. "Anthraxolites and impsonites are of secondary origin, but it is difficult to ascertain their point of entry in the secondary development track. They are normally described as being homogeneous and structureless; however, six of the twelve samples examined during this study possess a fine crystalline structure. The presence of crystalline material provides a basis for further speculation on their origin, as the conditions for crystallization in organic materials limit the various possibilities. It is thought that the material must have been quite aromatic in composition during deposition and that it probably migrated in an aqueous environment. It is also suggested that the migrating fraction originated as an alteration product of primary sedimented organic matter"--Abstract. Includes abstract in French. gccst Minerals Canada.
