isotopic element

The major compositions of amphibole in the granites, trace element composition and isotopic composition of granites were effective index to distinguish different metallogenic granitic bodies.

The effects of element sulfur on carbon isotopic fractionation of methane have been systematically studied by the simulation experiments of thermal transformated methane from organic matter.

Based on the carbon and oxygen isotopic composition and rare earth element (REE) patterns, the origin of the Dabaoshan deposit is considered to be related to the sea-floor thermal events.
