... epigenetic-hydrothermal deposits are classified according to their depth and temperature of formation - hypothermal deposits being deep-seated high temperature deposits; mesothermal deposits those formed at low temperatures and medium depths, and, thirdly, epithermal, near-surface deposits. Later terms include leptothermal to cover deposits gradational from mesothermal to epithermal, and telethermal for very low-temperature deposits formed at great distances from the source of the hydrothermal solutions which gave rise to them.  3, record 1, English, - leptothermal

leptothermal... Mineral grain size averages smaller and more variable than in mesothermal ores. There is an increased development of vugs toward the shallower limit of the zone. Rock alteration varies from sericitic to propylitic. Vertical depth range is estimated from 10, 000 to 15, 000 feet.  2, record 1, English, - leptothermal

On sépare quelquefois un type «leptothermal», qui correspond à la partie supérieure du mésothermal, sans posséder franchement les caractéristiques épithermales. Les textures rubanées et drusiques y sont plus développées que dans le mésothermal; le grain plus irrégulier.  1, record 1, French, - leptothermal

Factors influencing the filtration performance of geotextile can be classified into four categories-external conditions(hydraulic gradient and loading state) ;(bio) chemical conditions of fluent(pH, hardness(e. g. [Fe], [Mn], [Mg], [Ca]), redox potential(Eh) for iron ochre, BOD and COD of water(substrate type/concentration), osmotic pressure and dissolved oxygen) ;the properties of basement material(coefficient of uniformity(Cu), coefficient of gradation(Cc), plastic index(PI), double hydrometer ratio(DHR) for dispersive clay, particle shape and grain hardness for granular soil, compaction degree of soil and saturation degree) ;and the properties of geotextile(filtration opening size(FOS), apparent opening size(AOS), fiber density, textile bulk density(mass/area), porosity, thickness and fiber material)... screen test results clearly indicated that the height of self filtration is proportional to the constriction size(D_c) of granular filter used. Additionally, they suggested the filter opening size value should be within the range between d₅₀ and d₈₀ for linearly graded soil and within the flat range in gap graded soil.  2, record 2, English, - opening%20size

Pour les géotextiles utilisés comme filtres, on mesurera par commodité la probabilité de passage des particules de sol d'un diamètre connu. On assimile ainsi le géotextile à un tamis. On enregistre la taille maximale des particules traversant le tamis, mesure assimilée à un diamètre, d'où l'expression «diamètre de filtration». Plusieurs principes et méthodes sont actuellement utilisés pour définir cette caractéristique : tamisage à sec de billes de verre calibrées [...]; tamisage à sec de particules de sol [...]; tamisage de sol à l'humide [...]; tamisage de sol sous régime hydrodynamique.  4, record 2, French, - ouverture%20de%20filtration

On parle d'ouverture de filtration déterminée par tamisage à sec (en anglais : AOS; apparent opening size) et d'ouverture de filtration déterminée par tamisage hydrodynamique (en anglais : FOS; filtration opening size).
