Interesting EPMA olivine minor and trace element results!

After three days EPMA parameters setting, data calibration and quantification. I was able to obtain high precision EPMA olivine minor and trace elements for EPR 8°20' seamount and Siqueiros Transform lava samples. 

The data is very promising. They record different variation patterns for some key petrogenetic elements such as Ca, Ti, Ni, Mn, Al, etc. Olivine with mantle and igneous origins are also identified, which can help unravel mantle and magma history. More info will be explored!
