[A] tropical karst characterized by vertical rock blades fretted sharped by dissolution.  3, fiche 2, Anglais, - pinnacle%20karst

Record number: 2, Textual support number: 1 CONT

In a type of karst known as cutter-and-pinnacle karst, the contact between bedrock and soil overburden is very irregular... Water preferentially dissolves bedrock along some planar feature, such as bedding, joints, or fractures, whichever is the easier path. Roughly vertical, solutionally widened joints are called cutters, or grikes. Cutters are generally filled with soil. The bedrock that remains between cutters may be reduced to relatively narrow "ridges" of rock, called pinnacles, particularly where cutters are closely spaced. Cutter-and-pinnacle karst(or simply "pinnacle karst" for short) is common in many of the carbonate valleys in Maryland...... in pinnacle karst, part of the foundation may be supported by a bedrock pinnacle and part may be supported by a cutter(soil-filled). The result can be differential settling of the building, which may produce cracks in the walls, foundation, and floor... compromise the structural soundness of the bearing walls and, therefore, place the safety of the whole structure in doubt.  2, fiche 2, Anglais, - pinnacle%20karst

Le karst à pinacles de Mulu se distingue de celui de la Forêt de pierre de Lunan, en Chine. En outre, il est plus vaste et dans un état plus naturel. Il est également différent des pinacles que l'on trouve dans le Bien du patrimoine mondial de Tsingy de Bemaraha, à Madagascar car il est adossé à une grande montagne et non sous forme de plateau découpé créé au-dessous de plans de litage principaux. Enfin, le contraste est net entre les grottes de Mulu qui ont évolué sur une échelle aussi gigantesque, par un processus de dissolution, et celles de Mammoth (États-Unis) qui possède des réseaux plus longs de petits passages et de Carlsbad (États-Unis) qui a essentiellement évolué grâce à des processus hydrothermiques.  2, fiche 2, Français, - karst%20%C3%A0%20pinacles

Permeability that varies with direction of flow through the porous medium.  1, fiche 3, Anglais, - directional%20permeability

Record number: 3, Textual support number: 1 OBS

Lateral permeability contrast can be particularly important in fractured formations, where effective permeability in the direction of the fractures may be many times greater than the matrix permeability. If the permeability in one direction is significantly more than in the other, the flow pattern may more closely approximate linear flow than radial flow. This can be detected from well-test data. Likewise, laminations in most clastic formations cause the permeability normal to the bedding plane to be less than the lateral permeability parallel to bedding. This is called vertical to horizontal permeability anisotropy.  1, fiche 3, Anglais, - directional%20permeability

The angle that a structural surface, e. g. a bedding or fault plane, makes with the horizontal, measured in any random, vertical section, rather than perpendicular to the strike. It varies from nearly zero to nearly the true dip, depending on whether the random section is close to the direction of the strike or of the dip.  1, fiche 5, Anglais, - apparent%20dip
