(Cont.) Differences in the absolute and relative concentrations of NH3 and organic compounds and the stable carbon isotopic compositions of the C1-C3 organic compounds suggest that the three fields represent a continuum in terms of the extent of secondary alteration of the aqueous organic compounds, with the Dead Dog fluids the least altered, the MEF fluids the most altered and ODP Mound fluids in an intermediate state. At the two Middle Valley sites, the greater extent of alteration in the ODP Mound fluids as compared to the Dead Dog fluids is due either to higher temperatures in the subsurface reaction zone, or a greater residence time of the fluids at high temperatures. Higher reaction zone temperatures at the ODP Mound field than at the Dead Dog field are consistent with differences in endmember Cl concentrations between the two fields. The greater extent of alteration in the MEF fluids is caused by relatively oxidizing conditions in the subsurface reaction zone that promote faster reaction kinetics. Temperatures in the subsurface reaction zones calculated by assuming equilibrium among aqueous alkanes, alkenes and hydrogen are
