We apply a combination of classic and state-of-the-art techniques to conduct petrography observation, whole rock analysis and in situ micro-/nano-analysis of phases in igneous rocks.

(In-house) Optical microscope
@ DES, HKU
Zeiss Microscope Axiolab 5
This microscope works well for conducting basic petrography observation (transmitted & reflected light) and acquiring high-quality images for publication.
PI: Dr. Weiran Li
(In-house) Electron Microprobe
@ DES, HKU
JEOL JXA-8230 SuperProbe
This electron microprobe works well for measuring elemental concentrations in minerals and volcanic glass/glass inclusions.

Scanning electron microscope (SEM)
@ EMU, HKU
The Hitachi S-3400N SEM works well for quick identification of different phases in rocks and observation of textures and zonation patterns via backscattered electron (BSE), X-ray and cathodoluminescence (CL) imaging.
The SEM is run by the Electron Microprobe Unit of HKU which also houses other instruments such as TEM and FIB (more information at emunit.hku.hk)
