By the removal of soluble material from the original substance the insoluble material remaining may form valuable residual deposits. From carbonates and silicates in the original rock may be converted into practically insoluble oxides, which form iron ores as rock weathers; silica may be leached from kaolin, leaving the insoluble hydrous aluminum oxide, bauxite, a most important aluminum ore. Such deposits are generally formed in warm moist climates and would not be found in areas which have been glaciated.  3, record 1, English, - residual%20deposit

Gîtes résiduels. - Sous l'action des eaux superficielles ou hydrothermales, la roche-mère est désagrégée et subit parfois des transformations chimiques susceptibles de fournir des substances utiles [...] Ce sont des gîtes d'éluvion que l'on peut opposer aux gîtes d'illuvion (zone de cimentation) où le lessivage des couches supérieures provoque la formation d'incrustations, de concrétions ou de cimentations dans les couches sous-jacentes : le fer de certaines latérites [...] et surtout l'aluminium dans les bauxites appartiennent à ce type de gisement.  4, record 1, French, - gisement%20r%C3%A9siduel

Gisements résiduels. L'altération réduit les roches en fragments de toutes dimensions et détermine [...] la ségrégation des divers minéraux [...] Le départ successif des matériaux solubles, causé par les eaux météoriques, entraîne un enrichissement naturel en certains minéraux; c'est ainsi que naît un gisement résiduel.  5, record 1, French, - gisement%20r%C3%A9siduel

There are two forms of injection into deep geologic formations that have been suggested or used for LLW disposal : hydrofracture and deep well injection. Both methods are primarily useful only for liquid or finely ground wastes. They both take precautions to prevent contaminating useful aquifers by carefully selecting the geologic formations into which the waste is injected. Hydrofracture disposal also uses a very insoluble waste form. Generally, hydrofracture involves injection of a mixture of waste and liquid grouting materials under high pressure into a deep layered rock formation such as shale. The injected material causes layers of rock to separate and the material forms flat "sheets" extending out from the injection well. The grout causes some surface uplift near the injection well.  1, record 4, English, - hydrofracture%20disposal

Because of difficulty in transporting liquid wastes safely, the hydrofracture facility must be located near the source of the waste. A hydrofracture site requires large, generally impermeable (to nearby aquifers) layered formations that fracture horizontally. The surface area needed and visual impact of a hydrofracture facility are relatively small. Major barriers to nuclide release are the grout (waste form) and the geologic formation used. Perhaps the greatest problem with hydraulic injection is that there is little control of fracture propagation and it is not possible to define the final geometry of the grout/waste sheets from the surface.  2, record 4, English, - hydrofracture%20disposal

Stylolites... are irregular seams in soluble rocks resulting from solution along surfaces grossly perpendicular to contemporaneous compression : the seam contains the insoluble residue. Displaced primary structures show that as much as 40 per cent of the rock may dissolve in this way, but usually the percentage is much smaller.  1, record 5, English, - stylolite
