The electron microscopy laboratory (EML) is a service and research unit of the Institute of Geology and Geophysics, Chinese Academy of Sciences (IGGCAS), and is open to scientists from universities, government and industrial laboratories. The Laboratory was established for the purpose of conducting fundamental research relating microstructure and chemical composition characteristics to the fields of geochronology, geosphere deep dynamics, Earth evolution, cosmochemistry, comparative planetology, mineral resources etc.

The laboratory currently maintains an SEM (LEO1450VP), dual-beam FIB/SEM system (Zeiss Auriga Compact), and TEM (JEM-2100). The three facilities are all equipped with Energy Dispersive Spectrometers (EDS), which can provide composition information. Students and researchers can use these facilities once they have acquired basic training.
