Abstract:
Microthermometry of 400 secondary inclusions from the B zone and D zone of the Henderson ore bodies shows the presence of two coexisting fluids, one an aqueous chloride solution, highly charged with salts (both NaCl and CaCl2) and the other rich in methane. Analyses of dissolved ions of 16 samples indicate that Na+ and Ca represent nearly the total quantity of dissolved cations in the fluids. The temperature of formation established from the relation of NaCl saturation is in the order of 240° ± 10° C. Utilising the isochore of methane to trace the isochore of brine, the pressure is deduced to be around 800 bar. Possible genetic implications in relation to the fluids are discussed.
