Scanning Electron Microscope images, collected at UH Hilo, showing a fragment of lava collected from the Puʻu ʻŌʻō lava pond in November 2013. The bar scale at the right is 300 microns (0.012 in). The mostly uniform light gray is basalt glass and darker gray crystals are olivine (left) and pyroxene (right). Both crystals contain melt inclusions comprised of light gray glass.
