The images are of an olivine crystal from a glassy spatter sample taken from the ongoing Pu`u `O`o eruption of Kilauea Volcano here on the Big Island of Hawai`i.

The University of Hawaii at Hilo ARL SEMQ electron microprobe has been completely rennovated thanks to a grant from NSF (Award #. 0116904) and assistance from the USGS Hawaiian Volcano Observatory. The upgrades were done with the help of Don Lesher at Advanced Microbeam. The ARL SEMQ microprobe is running the most recent version of Probe for Windows analytical software, which is fully integrated with image analysis software and hardware from SIS. The microprobe is capable of quantitatively analyzing spots of 1-2 microns and can also produce backscatter electron and x-ray element maps. The microprobe is housed in the GeoArcheology laboratory in the Geology Department along with a QuanX EDXRF capable of analyzing whole rocks. Both instruments are wired to the adjacent teaching laboratory and can be used by students as part of Geology and Archeology courses.

UHH/HVO Microprobe
We are currently using the microprobe to investigate how lava tubes form by analyzing minerals and glasses collected from the inside of recently active tubes. We are also studying the chemistry changes in Kilauea's magma chamber and changes in chemistry related to lava flow morphology.

The UHH/HVO microprobe is run by Associate Professor Ken Hon and was funded by NSF Major Research Instrumentaion Grant # 0116904 and the US Geological Survey. The website and sample databases were constructed with help from Chelsie Javar under an internship funded by a NSF STEM grant to the UHH Keaholoa Program. (email to kenhon)
