WebIn geology, lamination (from Latin lāmina 'thin layer') is a small-scale sequence of fine layers ( laminae; singular: lamina) that occurs in sedimentary rocks. Laminae are normally smaller and less pronounced than bedding. Lamination is often regarded as planar structures one centimetre or less in thickness, whereas bedding layers are greater ... Webfoliation are called foliation joints. 2. Bedding plane separation.— A separation along bedding planes after exposure due to stress relief or slaking. 3. Random fracture.—A fracture which does not belong to a joint set, often with rough, highly irregular, and nonplanar surfaces along which there has been no obvious displacement. 4. Shear.— suction cup with threaded screw
6.3: Metamorphic Textures - Geosciences LibreTexts
WebA modeling method that takes into account known points on a geological interface and plane orientation data such as stratification or foliation planes is described and tested. The orientations data do not necessarily belong to one of the interfaces but are assumed to sample the main anisotropy of a geological formation as in current geological situations. … WebIf the object you are measuring is a plane, then it's a foliation. If the object is a line, then it's a lineation. It is that simple. (Actually some foliations are curved planes in reality). It sounds like you are confusing some generic terms for data types (foliation and lineation) with specific metamorphic rock features. Webfoliation are called foliation joints. 2. Bedding plane separation.— A separation along … suction cup window holder
