Pitted outwash
| Глоссарий геологических терминов |
Outwash deposits with surficial pits or kettles, produced by the partial or complete burial of glacial ice by outwash and the subsequent thaw of the ice and collapse of the surficial materials. compare - pitted outwash plain. gg

Outwash, английский
Зандровые отложения
Outwash delta, английский
A relict (inactive) delta composed of glaciofluvial sediments formed where a sediment laden outwash river emptied into an open lake, commonly a proglacial lake. sediment attributes include very gently dipping topset beds (coarser textures) and steeply dipping foreset beds (finer textures). sw & gm
Outwash fan, английский
A fan-shaped accumulation of outwash deposited by meltwater streams in front of the end or recessional moraine of a glacier. coalescing outwash fans form an outwash plain. gg
Outwash plain, английский
An extensive lowland area of coarse textured, glaciofluvial material. an outwash plain is commonly smooth; where pitted, due to melt-out of incorporated ice masses (pitted outwash plain), it is generally low in relief and largely retains its original gradient. compare - outwash, pitted outwash plain, collapsed outwash plain, kettles; also called sandur. sw & hp
Outwash terrace, английский
A flat-topped bank of outwash with an abrupt outer face (scarp or riser) extending along a valley downstream from an outwash plain or terminal moraine; a valley train deposit. compare - kame terrace, valley train. sw
Outwash [glacial geology], английский
Stratified and sorted sediments (chiefly sand and gravel) removed or "washed out" from a glacier by melt-water streams and deposited in front of or beyond the end moraine or the margin of a glacier. the coarser material is deposited nearer to the ice. compare - pitted outwash, drift, esker, kame, till. sw & gg
Pitt, английский
Pittacium, латинский
Pittacium [ii, n], латинский
Pittacium [ii, n] (cursale, cursuale), pittaciunculum [i, n], латинский
Pittacium [ii, n] cursuale (epistulare), латинский
Pittacium, ii, n, латинский
Pittasphalt, английский
Pitted, английский
Shape term for a rock particle with an uneven surface texture
Pitted outwash plain, английский
An outwash plain marked by many irregular depressions such as kettles, shallow pits, and potholes which formed by melting of incorporated ice masses; much of the gradient and internal structures of the original plain remain intact; many are found in wi, mn, mi, and in. compare - collapsed outwash plain, outwash, pitted outwash. gg
Pitted outwash terrace, английский
A relict glaciofluvial terrace that retains its original attitude, composed of undistorted outwash sediments and depositional structures and whose surface is pock-marked with numerous potholes or kettle depressions. compare - collapsed outwash plain. sw
Pitter, английский
Машинка для удаления косточек из плодов
Pitticite, английский
Pitting, английский
- A form of extremely localized attack characterized by holes in the metal. pitting is one of the most destructive and insidious forms of corrosion. depending on the environment and the material, a pit may take months, or even years, to become visible.
- Surface irregularities that may develop on lamp pins, bases, and sockets which affect lamp-life and socket operation. tip: replace pitted lamps and sockets asap.
- The formation of hollows in the skin
- Chemical or mechanical surface damage to a metal involving the formation of pits or holes. see also scuffing,
- Forming small sharp cavities in a metal surface by nonuniform electrodeposition or by corrosion.
- Discontinuity consisting of surface cavities. see also cavitation fatigue.
- Forming of small cavity discontinuities in a surface by corrosion, wear, or other degradation. see also cavitation erosion. planck’s distribution law: fundamental law that relates the emitted energy spectral radiance to wavelength and to emitted surface temperature. see also blackbody; incandescence; stefan-boltzmann law; wien’s law.
Pitting and piling, английский
Erosion of one ignition contact breaker point and deposition of metal on the other resulting from high temperature vaporization of the metal, or incorrect condenser capacity. pivot pin (1) vertical or inclined shaft about which a steered wheel assembly pivots. also kingpin

Pinnate drainage pattern, английский
A variation of the dendritic drainage pattern in which the main stream receives many closely spaced, subparallel tributaries that join it at slightly acute angles upstream, resembling in plan a feather. they typically form on steep slopes with soils that have a high silt content; such as loess landscapes or fine-textured flood plains. sw, gg, wa
