Slate is a fine-grained, foliated, homogeneous, ... reduction spheres form around iron nuclei, leaving a light-green, spotted texture. These spheres are sometimes ...
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.
Rocks exhibiting foliation include the standard sequence formed by the prograde metamorphism of mudrocks; slate, phyllite, schist and gneiss. The slatey cleavage typical of slate is due to the preferred orientation of microscopic phyllosilicate crystals. In gneiss, the foliation is more typically represented by compositional banding due to ...
In computer graphics, relief mapping is a texture mapping technique first introduced in 2000 [1] used to render the surface details of three-dimensional objects accurately and efficiently. [2] It can produce accurate depictions of self-occlusion, self-shadowing, and parallax. [3] It is a form of short-distance ray tracing done in a pixel shader.
Granoblastic is an adjective describing an anhedral phaneritic equi-granular metamorphic rock texture. Granoblastic texture is typical of quartzite, marble, charnockites and other non-foliated metamorphic rocks without porphyroblasts. Characteristics defining granoblastic texture include: grains visible to the unaided eye, sutured boundaries ...

Carmelo Formation (conglomerate) at Point Lobos Nagdong Formation at Sangju. Conglomerate (/ k ən ˈ ɡ l ɒ m ər ɪ t /) is a sedimentary rock made up of rounded gravel-sized pieces of rock surrounded by finer-grained sediments (such as sand, silt, or clay).
This texture reflects a high content of platy minerals, such as mica, talc, chlorite, or graphite. These are often interleaved with more granular minerals, such as feldspar or quartz . Schist typically forms during regional metamorphism accompanying the process of mountain building ( orogeny ) and usually reflects a medium grade of metamorphism.
