Crystalline texture
WebJan 20, 2024 · Crystalline texture and c-axis orientation of the 2083 m ice core at Vostok Station, covering more than 150kyear, reveal the existence of strong anisotropics. Changes in crystal size with depth are compatible with the growth of grains driven by the free energy of grain boundaries. A smaller growth rate appears to be associated with cold periods. WebTexture 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). Noncarbonate chemical….

WebJan 1, 2006 · Many materials in asymmetric (non-cubic) crystalline structures have anisotropic magnetic susceptibilities, Δ χ = χ ∥ − χ ⊥, associated with their crystal structures, where χ ∥ and χ ⊥ are the susceptibilities parallel and perpendicular to the magnetic principal axis, respectively. When a single crystal of these materials is placed in a magnetic field, … Weblimestone, sedimentary rock composed mainly of calcium carbonate (CaCO 3 ), usually in the form of calcite or aragonite. It may contain considerable amounts of magnesium carbonate (dolomite) as well; minor constituents …
Webcrystalline-granular texture. A primary texture of an igneous rock due to crystallization from a fluid medium. Want to thank TFD for its existence? WebA completely glassy texture is called holohyaline texture. Two stages of cooling, i.e. slow cooling to grow a few large crystals, followed by rapid cooling to grow many smaller crystals could result in a porphyritic texture, a texture with two or …

Crystalline igneous rocks that have crystals large enough to be seen without the aid of magnification are said to be: Phaneritic or coarse grained. WebCrystallite —minute body of unknown mineralogical composition or crystal form that does not polarize light. Curlicue —flattened glass fragments and shards resulting from flow and compaction; welded ash-flow tuff, Marysvale, Utah, U.S.A., PPL, x200.
WebThe thin-walled airfoil areas of as-cast single-crystalline turbine blades made of CMSX-4 superalloy were studied. The blades were produced by the industrial Bridgman technique at withdrawal rates of 2, 3 and 4 mm/min. The angle between the [001] crystallographic direction and blade axis, related to the primary orientation, was defined by the Ω …
