LA-ICP-MS/MS Laboratory

“Congratulations to Dr. Shiqiang Huang for receiving the 2024 Early Career Researchers Award of the International Association of Geoanalysts (IAG)!”

Equipment

Capacities

  • U-Pb dating (zircon, garnet, cassiterite)
  • In-situ Rb-Sr dating of micas (no mineral separation needed)
  • Mineral trace element analysis (including Cl, Br, and low level sulfur (~10 ppm S))
  • Mineral trace element mapping. Examples:
Mapping Pyrite
Garnet 3 ppm No Inclusion

Capacities in Development

  • U-Pb dating of titanite, monazite, apatite, and wolframite
  • In-situ S isotope composition analysis
