The Monterey Formation of Miocene age is an important source rock for petroleum in California, USA (Orr, 1986 hjiz et al, 1990 Aizenshtat et al, 1999 Schouten et al, 2001). In this Formation, extensive sulfate reduction was controlled by insufficient sulfate supply. Zaback and Pratt (1992) and Zaback et al. (1993) argue that the observed diversity in pyrite sulfur isotopes from —18 to +15%o may relate to the timing of its formation, in the diagenesis sequence. Thus, the range of values for pyrite in this formation is somewhat heavy. The relation between timing and sulfur isotope imprint of conditions of sedimentation is discussed in depth in Part 1.

Worldwide, the amount of energy available from coal is estimated to be about ten times greater than the amount available from all petroleum and natural gas reserves combined. Coal is also the filthiest fossil fuel because it contains large amounts of such impurities as sulfur, toxic heavy metals, and radioactive isotopes. Burning coal is therefore one of the quickest ways to introduce a variety of pollutants into the air. More than half of the sulfur dioxide and about 30 percent of the nitrogen oxides released into the atmosphere by humans come from the combustion of coal. As with other fossil fuels, the combustion of coal also produces large amounts of carbon dioxide.

Sulfur (Z = 16) has 4 stable isotopes of which is by far the most abundant in nature (95,02%). The others are - - S (0.75%), (4.21%), and (0.02%). These abundances vary somewhat depending on the source of the sulfur, and this prevents the atomic weight of sulfur being quoted for genera use more precisely than 32.066(6) (p. 17), The variability is a valuable geochemical indication of the source of the sulfur and the isotope ratios of sulfur-containing impurities can even be used to identify the probable source of petroleum samples. ...

The first section of the volume is dedicated to stable isotopic studies of all kinds. Included in this section are investigations of carbon, sulfur, oxygen and boron from terrestrial and extraterrestrial systems. The second section of the volume focuses on geochemical investigations of environmental and atmospheric chemistry problems. The third section of the volume is concerned with various aspects of petroleum geochemistry, and the final section includes investigations of recent and ancient sediments.
