Lava in the Lake

BSD image of the Sample

Under the BSD i noticed these small cavities in the sample which provieds some support to the theory that they are igneous. This happens as the lava cools quickly the gases inside try to escape making the resulting rock very porous in nature.

Using the SE2 detector I zoomed in on the cavity observed in the BSD, to discover a beautiful crystalline structure.

X-Ray
X-Ray map

I decided to run an X-Ray map to determine the elemental composition of the sample. If the rocks were residue from an industrial coke plant, I'd expect to see large amounts of carbon and little of anything else. This image is showing large amounts of Aluminum in the sample

Spectrual analysis

Spectrum analysis was taken to provide a quick idea of whether or not more imaging should be done. For instance, If it had been mostly made of carbon, we would have likely been able move on to other samples.
