Greywacke or graywacke (German grauwacke, signifying a grey, earthy rock) is a variety of sandstone generally characterized by its hardness (6–7 on Mohs scale), dark color, and poorly sorted angular grains of quartz, feldspar, and small rock fragments or sand-size lithic fragments set in a compact, clay-fine matrix.
960H is a resolution used in analog CCTV equipment. 960H represents the number of horizontal pixels in a video signal transmitted from a camera or received by a DVR (Digital Video Recorder). The resolution of 960H depends on whether the equipment is PAL or NTSC based: 960H represents 960 x 576 (PAL) or 960 x 480 (NTSC) pixels.
Quartzite can have a grainy, glassy, sandpaper-like surface. Quartzite is a hard, non-foliated metamorphic rock which was originally pure quartz sandstone. [1] [2] Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts.
Tiger also introduced Quartz 2D Extreme: optional graphics processor (GPU) acceleration for Quartz 2D, although it is not an officially supported feature. [7] Quartz 2D Extreme is disabled by default in Mac OS X 10.4 because it may lead to video redraw issues or kernel panics. [8] In Mac OS X Leopard, Quartz 2D Extreme was renamed QuartzGL.
The size of the silica particles influences inversions, conversions and other properties of the ceramic body. [7] [8] [9] The presence of other ceramic raw materials can influence the thermal behaviour of quartz, including: Talc promotes the conversion of quartz to cristobalite, and if sufficient alumina is available the formation of cordierite.
Smoky quartz is a brownish grey, translucent variety of quartz that ranges in clarity from almost complete transparency to an almost-opaque brownish-gray or black crystals. [6] The color of smoky quartz is produced when natural radiation, emitted from the surrounding rock, activates color centers around aluminum impurities within the ...
