Todorokite - Appearance

Appearance

Todorokite occurs as spongy banded and reniform (kidney-shaped) aggregates composed of minute lathlike crystals. The crystals are flattened parallel to the plane containing the a and c crystal axes, and elongated parallel to the c axis. Minerals of the hollandite-cryptomelane and romanèchite groups also have fibrous or acicular habits and two perfect cleavages parallel to the fiber axis. Todorokite is dark brown to brownish black in color and brown in transmitted light. It has a black to dark brown streak and the luster is metallic to dull, but silky in aggregates. It is opaque in all but the thinnest slivers, which are transparent.

Famous quotes containing the word appearance:

    The actor is too prone to exaggerate his powers; he wants to play Hamlet when his appearance is more suitable to King Lear.
    Sarah Bernhardt (1845–1923)

    This mesa plain had an appearance of great antiquity, and of incompleteness; as if, with all the materials for world-making assembled, the Creator had desisted, gone away and left everything on the point of being brought together, on the eve of being arranged into mountain, plain, plateau. The country was still waiting to be made into a landscape.
    Willa Cather (1873–1947)

    The aim of science is to apprehend this purely intelligible world as a thing in itself, an object which is what it is independently of all thinking, and thus antithetical to the sensible world.... The world of thought is the universal, the timeless and spaceless, the absolutely necessary, whereas the world of sense is the contingent, the changing and moving appearance which somehow indicates or symbolizes it.
    —R.G. (Robin George)
