-phile
   -دوست   
-dust

Fr.: -phile   

A combining form meaning "lover of, attracted to" that specified by the initial element.

-phile, also -phil, from M.L. -philus, from Gk. -philos, common suffix in personal names (such as Theophilos), from philos "loving, dear," from philein "to love," which is of unknown origin.

-dust, from dust "friend; lover;" Mid.Pers. dôst "friend;" O.Pers. dauštar- "friend;" Av. zaoša- "pleasure," zuš- "to like," zušta- "loved;" cf. Skt. jos- "to like, be pleased, enjoy," jósa- "satisfaction," jóstar- "loving;" Gk. geuomai "to taste;" L. gustare "to taste."

atmophile
  اتمودوست، هوادوست   
atmodust, havâdust

Fr.: atmophile   

atmophile element.

atmo-; → phile.

atmophile element
  بن‌پار ِ اتمودوست، ~ هوادوست، ~ گازدوست   
bonpâr-e atmodust, ~ havâdust, ~ goazdust

Fr.: élément atmophile   

In the → Goldschmidt classification, a → chemical element that is extremely → volatile, i.e., forms a gas or liquid at the surface of the Earth. The atmophile elements are usually concentrated in the terrestrial → atmosphere and → hydrosphere. They are → hydrogen (H), → carbon (C), → nitrogen (N), and → noble gas/qot>es, namely → helium (He), → neion (Ne), → argon (Ar), → krypton (Kr), → xenon (Xe), and → radon (Rn) (Pinti D.L., 2017, Atmophile Elements. In: White W. (eds) Encyclopedia of Geochemistry, Springer).

atmophile; → element.

chalcophile
  خالکودوست، مسدوست   
xâlkdust, mesdust

Fr.: élémznt chalcophilz   

chalcophile element.

chalco-; → -phile.

chalcophile element
  بن‌پار ِ خالکودوست، ~ مسدوست   
bonpâr-e xâlkdust, ~ mesdust

Fr.: élément chalcophile   

In the → Goldschmidt classification, a → chemical element that has an → affinity for sulphur, and therefore tending to be more abundant in sulphide minerals and ores than in other types of rock. This group is depleted in the silicate Earth and may be concentrated in the core. The group includes → silver (Ag), → arsenic (As), → bismuth (Bi), → cadmium (Cd), → copper (Cu), → mercury (Hg), → indium (In), → lead (Pb), → sulfur (S), → antimony (Sb), → selenium (Se), → tellurium (Te), and → thallium (Tl). As a consequence of their relatively low condensation temperatures (500-1100 K), most of these elements are depleted in terrestrial planets with respect to chondrites.

chalcophile; → element.

extremophile
  استومدوست   
ostomdust

Fr.: extrêmophile   

A → microorganism with the ability to thrive in extreme environmental conditions that would kill other species. These conditions include high temperatures, very low temperatures, high pressures, high levels of radiation, and high concentrations of salt in water.

extreme; → -phile.

highly siderophile element (HSE)
  بن‌پار ِ بسیار آهندوست   
bonpâr-e besyâr âhandust

Fr.: élément hautement sidérophile   

A → chemical element that is → geochemically characterized as having a strong → affinity to partition into → metals relative to → silicates. The highly siderophile elements, → ruthenium (Ru), → rhodium (Rh), → palladium (Pd), → rhenium (Re), → osmium (Os), → iridium (Ir), → platinum (Pt), and → gold (Au), are of interest to planetary scientists because they give insights into the early history of → accretion and → differentiation. HSEs prefer to reside in the metal of planetary cores. Therefore, the HSEs found in planetary → mantles are considered to be overabundant relative to their known preferences for metal over silicate. Therefore, it has been inferred that processes other than → equilibrium partitioning have been responsible for establishing the abundances of → mantle siderophiles. A detailed understanding of the absolute → concentrations and relative abundances of the HSEs may therefore give important insights into the earliest history of a planet (Jones et al., 2003, Chemical Geology 196, 21).

From Gk. sidero-, from sideros "iron" + → -phile.

Âhandust, from âhan, → iron, + -dust, → -phile.

lithophile
  سنگدوست، لیتودوست   
sangdust, litodust

Fr.: lithophile   

lithophile element.

litho-; → -phile.

lithophile element
  بن‌پار ِ سنگدوست، ~ لیتودوست   
bonpâr-e sangdust, ~ litodust

Fr.: élément lithophile   

In the → Goldschmidt classification, a → chemical element that shows an → affinity for → silicate phases and is concentrated in the silicate portion of the Earth (→ crust and → mantle). This group includes → lithium (Li), → beryllium (Be), → sodium (Na), → magnesium (Mg), → potassium (K), → calcium (Ca), → barium (Ba), → titanium (Ti), → chromium (Cr), → aluminium (Al), → silicon (Si), → phosphorus (P), → chlorine (Cl), etc.

lithophile; → element.

siderophile
  آهندوست، سیدرندوست   
âhandust, siderodust

Fr.: sidérophile   

siderophile element.

sidero-; → -phile.

In the → Goldschmidt classification, any → chemical element that has an → affinity to combine with → iron rather than some other element. These elements are concentrated in the → Earth's core. The group includes → iron (Fe), → nickle (Ni), → cobalt (Co), → platinum (Pt), → gold (Au), → tin (Zn), and → tantalum (Ta). The siderophile elements include → highly siderophile element (HSE).

siderophile; → element.
