Local Rocks and Minerals
of the San Gabriel Mountains

As I collect rock and mineral specimens from here in the San Gabriel Mountains, I am sending samples to Cannon Microprobe laboratory for elemental analyses and identification (Scanning Electron Microscope and possibly some X-Ray Diffraction when I can afford it).

Here I post rock/mineral photos and the accompanying spectra plots that tell you which elements (Elements 1-10 aren't found due to limitations in the equipment) are found in the specimen.
