A most remarkable result in the chemical study of ancient morphologies is the complex chemical composition, comprizing carbonaceous materials and different inorganic materials such as carbonates, iron sulphides and iron oxides. It can be shown that most of the inorganic constituents are biominerals produced directly or indirectly by the life activity of the involved organisms. So also these products are chemical fossils and, therefore, merit adequate consideration in our analyses. [Pg.4]
