Figure 3.3 Sources of hydrocarbons in geological situations, with regard to the evolution of organic matter. Geochemical fossils represent a first source of hydrocarbons in the subsurface (black solid arrows). Degradation of kerogen represents a second source of hydrocarbons (grey dotted arrows) (from Tissot and Welte, 1984. Reprinted by permission of Springer-Verlag).

Geochemical fossil A distinctive organic compound that can be isolated from a sedimentary deposit and that can provide evidence of a specific organism or group of organisms that lived in the past. [Pg.462]

In Chapter 2, a geochemical, geological and mineralogical summary of active subaerial and submarine back-arc basin hydrothermal systems and mineralizations is given. The characteristic features of above-fossil and active subaerial and submarine hydrothermal systems are compared with fossil hydrothermal systems (epithermal vein-type and Kuroko deposits), and the causes for the differences in the characteristic features are considered. Characteristic features of Paleozoic-Mesozoic volcanogenic stratiform Cu deposits (Besshi-type deposits) are compared with those of midoceanic ridge deposits and Kuroko deposits. [Pg.474]
