Gold is the most important placer mineral... Gold placers as a rule are easily discovered and worked... Gold placers may be formed by rapid erosion of hard rocks, but such placers are not often rich and highly concentrated. In the great placer regions the concentration has generally been preceded by an epoch of deep secular decay of the surface... When the outcrops of gold-bearing veins are decomposed a gradual concentration of the gold follows, either directly over the primary deposits or on the gentle slopes immediately below.  3, record 1, English, - gold%20placer

Nous prenons comme exemple les «placers aurifères» [...] Ces dépôts aurifères, qui occupent certaines zones dans les alluvions, tapissant les vallées des cours d'eau ou formant des terrasses fluviales, proviennent de l'enlèvement des éluvions de filons aurifères par les émissaires à forte pente de ces cours d'eau. Ils sont en outre remaniés dans la suite par les crues.  4, record 1, French, - placer%20aurif%C3%A8re

[...] dans certains cas, les placers ont été protégés, conservés par une couverture, par exemple des coulées de laves, contre une érosion ultérieure. C'est le cas de certains placers aurifères du Victoria (Australie) [...]  5, record 1, French, - placer%20aurif%C3%A8re

Record number: 3, Textual support number: 2 CONT

Extremely fine gold particles are more readily transported, and their concentration(or dissemination) in the fluvial or littoral environment is determined by hydraulic sorting(flow separation), which is dependent on such factors as the size, shape, and specific gravity of individual grains in the sediment load, the velocity and degree of turbulence of water flow, and the nature of the stream bed...  1, record 3, English, - hydraulic%20sorting

Les particules d'or extrêmement fines sont plus facilement transportées et leur concentration (ou dissémination) dans le milieu fluvial ou littoral est attribuable au tri hydraulique (séparation par l'écoulement) qui dépend de certains facteurs comme la taille, la forme et la densité des grains individuels dans la charge sédimentaire, la vitesse et le degré de turbulence de l'eau et la nature du lit du cours d'eau [...]  1, record 3, French, - tri%20hydraulique

A vibrating condenser formed from two dissimilar metals, one of which is gold plated and coated with calcium palmitate, is used as the basis of this type of detection; the surface potential between the plates is modified by any changes in the gas composition and this leads to corresponding changes in the e. m. f., giving a signal proportional to the concentration.  1, record 5, English, - surface%20potential%20detection
