Onyx2, codenamed Kego, is a family of visualization systems. It was developed and manufactured by SGI, and introduced in 1996 to succeed the Onyx. Onyx2 architecture is based on Origin 2000 server plus graphics hardware. In 2000, the Onyx2 was succeeded by the Onyx 3000, and it was discontinued on June 27, 2003
Phonolite is an uncommon shallow intrusive or extrusive rock, of intermediate chemical composition between felsic and mafic, with texture ranging from aphanitic (fine-grained) to porphyritic (mixed fine- and coarse-grained). Phonolite is a variation of the igneous rock trachyte that contains nepheline or leucite rather than quartz. [1]
The RealityEngine2 is the original high-end graphics subsystem for the Onyx and was found in two different versions: deskside and rack. The deskside model has one GE10 (Geometry Engine) board with 12 Intel i860XP processors, up to four RM4 or RM5 (Raster Manager) boards, and a DG2 (Display Generator) board. [4]
Anthropic rock is synthetic or restructured rock formed by human activity. Concrete is recognized as a human-made rock constituted of natural and processed rock and having been developed since Ancient Rome. [23] Rock can also be modified with other substances to develop new forms, such as epoxy granite. [24]
Cryptocrystalline is a rock texture made up of such minute crystals that its crystalline nature is only vaguely revealed even microscopically [1] in thin section by transmitted polarized light. Among the sedimentary rocks, chert and flint are cryptocrystalline. Carbonado, a form of diamond, is also cryptocrystalline.
Igneous rock, with gray groundmass and white phenocrysts marked. Orthoclase phenocrysts within a finer-grained matrix of a granite porphyry. The matrix or groundmass of a rock is the finer-grained mass of material in which larger grains, crystals, or clasts are embedded.
Mylonite is a fine-grained, compact metamorphic rock produced by dynamic recrystallization of the constituent minerals resulting in a reduction of the grain size of the rock. Mylonites can have many different mineralogical compositions; it is a classification based on the textural appearance of the rock.
Serpentinite is a metamorphic rock composed predominantly of serpentine group minerals formed by serpentinization of mafic or ultramafic rocks. The ancient origin of the name is uncertain; it may be from the similarity of its texture or color to snake skin. [1] Greek pharmacologist Dioscorides (AD 50) recommended eating this rock to prevent ...
