At its launch, the Xbox 360 was available in two retail configurations: the morning "Xbox 360" package (unofficially known as the 20 GB Pro or Premium), priced at US$ 399.99 or £ 279.99, and the "Xbox 360 Core," priced at US$299.99 and £209.99. The original shipment of Xbox 360s included a cut-down version of the Media Remote as a promotion.
Jasper, an aggregate of microgranular quartz and/or cryptocrystalline chalcedony and other mineral phases, [1] [2] is an opaque, [3] impure variety of silica, usually red, yellow, brown or green in color; and rarely blue. The common red color is due to iron (III) inclusions. Jasper breaks with a smooth surface and is used for ornamentation or ...
The Xbox 360 technical specifications describe the various components of the Xbox 360 video game console.. The console features a port on the top when vertical (left side when horizontal) to which a custom-housed hard disk drive unit can be attached in sizes of either 20, 60, 120, 250, 320, 500 GB; and as of April 2015 all 2.5" SATA Hard Drives up to 2 TB, the user can use the format option ...
References. [2] [3] [4] Diopside is a monoclinic pyroxene mineral with composition MgCaSi. 2O. 6. It forms complete solid solution series with hedenbergite ( FeCaSi. 2O. 6) and augite, and partial solid solutions with orthopyroxene and pigeonite. It forms variably colored, but typically dull green crystals in the monoclinic prismatic class.
The structure of sodalite was first studied by Linus Pauling in 1930. [7] It is a cubic mineral of space group P 4 3n ( space group 218) which consists of an aluminosilicate cage network with Na + cations and chloride anions in the interframework. (There may be small amounts of other cations and anions instead.)
Chrome-bearing fuchsite (a variety of muscovite mica) is the classic inclusion and gives a silvery green or blue sheen. Oranges and browns are attributed to hematite or goethite. Because aventurine is a rock, its physical properties vary: its specific gravity may lie between 2.64–2.69 and its hardness is somewhat lower than single-crystal ...
Orbicular jasper from Madagascar. Orbicular jasper is a variety of jasper which contains variably-colored orbs or spherical inclusions or zones. In highly silicified rhyolite or tuff, quartz and feldspar crystallize in radial aggregates of needle-like crystals which provide the basis or seed for the orbicular structure seen in this kind of jasper.
