Application

Trace element determination in geology serves as a core methodology for geochemical research. We conduct in-situ microanalysis using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) or whole-rock analysis via high-resolution solution-based ICP-MS following acid digestion, enabling precise determination of critical trace elements—including rare earth elements, high-field-strength elements, and transition metals—in geological samples such as whole rocks and single minerals at ppm to ppb levels. The concentrations, assemblage characteristics, and specific elemental ratios (e.g., Nb/Ta, Zr/Hf, REE patterns) of these elements provide irreplaceable constraints for revealing magma source properties, degrees of partial melting and fractional crystallization, fluid metasomatism, sediment provenance, and ore deposit genesis. Our services are extensively applied to research and exploration practice in fields including fundamental petrology, economic geology, sedimentology, geodynamics, and planetary science.
