crystalline texture

Crystalline Material - an overview | ScienceDirect Topics

Crystalline materials display a specific packing order or organization of a constituent unit cell. This unit cell is the basic configuration of a crystal based on its principal composition. As described in Figure 1.6, the constituent chemical composition, in this case the atomic composition, determines the unit cell organization and the packing/organization within the unit cell.

Texture (crystalline) | Wiki | Everipedia

Texture (crystalline)'s wiki: In materials science, texture is the distribution of crystallographic orientations of a polycrystalline sample (it is also part of the geological fabric). A sample in which these orientations are fully random is said to have no distinct texture. If the crystallographic orientations are not random, but have some preferred orientation, then the sample has a weak ...

Texture | geology | Britannica.com

In sedimentary rock: Texture. Texture refers to the physical makeup of rock—namely, the size, shape, and arrangement (packing and orientation) of the discrete grains or particles of a sedimentary rock. Two main natural textural groupings exist for sedimentary rocks: clastic (or fragmental) and nonclastic (essentially crystalline).

Brief notes on the Texture of Sedimentary Rocks

The word 'texture' refers to the size, shape, packing and fabric of the components of the rock. Since the sedimentary rocks are broadly classified as (1) exogenetic or clastic rocks and (2) endogenetic rocks or the chemically precipitated amorphous or crystalline rocks, accordingly their texture are also classified into two broad categories.

Texture (crystalline) - Wikipedia

In materials science, texture is the distribution of crystallographic orientations of a polycrystalline sample (it is also part of the geological fabric).A sample in which these orientations are fully random is said to have no distinct texture. If the crystallographic orientations are not random, but have some preferred orientation, then the sample has a weak, moderate or strong texture.

Igneous rock composition and texture

How do composition and texture relate to igneous rocks? Igneous rocks are crystalline solids which cool from magma: the liquid phase of solid rock. Magmas occur at depth in the crust, and are said to exist in "magma chambers," a rather loose term indicating an area where the temperature is great enough to melt the rock, and the pressure is low enough to allow the material to expand and exist ...

Examples of Aphanitic Rocks (the two images below show a hand sample and a thin section of aphanitic textured rocks) : Aphanitic texture consists of small crystals that cannot be seen by the eye with or hand lens. The entire rock is made up of small crystals, which are generally less than 1/2 mm in size.

ROCK TEXTURE - City University of New York

All minerals are crystalline. Glass, however, is not crystalline - its atoms are arranged randomly - and therefore is not a mineral. For a review of the word crystalline, used in this sense, revisit 'Crystal City'. In a textural context, 'crystalline' means that the grains in a rock have an interlocking relationship.

SEDIMENTARY ROCKS TEXTURES - Santa Monica College

Chemical sedimentary rocks are crystalline, that is made of crystals interlocked with each other. Conceptually, that is the same texture we see in igneous and metamorphic rocks, but NOT in clastic sedimentary rocks. Chemical sedimentary rocks form because of the precipitation of crystals from aqueous (water) solutions and from chemical residues.

An introduction to crystal texture by XRD and TEM.

The crystallographic texture of the solid, hereinafter briefly crystal texture or texture, is understood to mean the statistical entity of the crystallite orientations in a polycrystal. In the narrower sense, however, one often means the deviations from the statistical randomness of orientations, or in other words, the presence of preferred ...

Sedimentary Textures and Classification of Clastic ...

This distinction is based primarily on texture. First determine if the rock has a (micro)clastic or (micro)crystalline texture. If the texture is (micro) crystalline, you are dealing with a chemical rock. If the texture is (micro) clastic, you must determine whether the rock is clastic or bioclastic. If clastic, use the clastic rock chart.
