Orientation distribution of microlites in obsidian

The shape and three-dimensional orientation distribution of microlites are measured in obsidian from Little Glass Mountain, CA. Measurements are made from thin sections using an image series of high magnification digital micrographs taken serially through different focal depths. These measurements agree well with the theoretically predicted and experimentally measured distribution of long slend...

The Origin of Color in “fire” Obsidian

A variety of obsidian from Glass Buttes, Oregon, known as “fi re” obsidian and named for thin layers showing various colors, was investigated with fi eld-emission scanning electron microscopy, X-ray energy-dispersive spectroscopy, electron back-scatter diffraction, and optical spectroscopy methods. Our study reveals that the thin layers mainly consist of concentrated nanometric crystals of magn...

Obsidian: GPU Programming in Haskell

Obsidian is a language for data-parallel programming embedded in Haskell. As the Obsidian programs are run, C code is generated. This C code can be compiled for an NVIDIA 8800 series GPU (Graphics Processing Unit), or for other high-end NVIDIA GPUs. The idea is that the style of programming used in Lava for structural hardware design [2] can be applied to data-parallel programming as well. Ther...

Geochemical Provenance of Obsidian Artefacts from the Msa Site of Porc Epic, Ethiopia*

Obsidian geochemical analysis has become an indispensable tool in archaeological research and has wide applications. However, in spite of the abundance of geological and archaeological obsidian, there has been virtually no such investigation in Ethiopia. Recent instrumental characterization of 31 obsidian artefacts from the Middle Stone Age site of Porc Epic and numerous obsidian geological sou...
