“Although in common use, the geochemistry of modern arc lavas is not a safe discriminator for the tectonic setting of Archaean volcanic rocks.”

“The same samples as used for geochemistry were investigated for their content of calcareous nannofossils.”

“Stereochemistry is also important in geology, especially mineralogy, with dealing with silicon based geochemistry.”

“Americans Mike Conway and Andy Macfarlane and Ecuadoran geochemist Luis LeMarie were going to insert temperature probes, known as thermocouples, into the fumaroles.”

“Hart is a geologist and isotope geochemist whose recent research has focused on the origin of hot spots and mantle plumes and on the dynamics and evolution of the deep Earth.”
