WebJun 21, 2024 · Example from An Introduction to Geology (source: Peter Davis; Open Geology ). Stretching lineations (also called object lineations) are linear fabrics outlined by deformed grains and objects in rocks. They commonly consist of mineral grains and aggregates that stretch, rotate, or grow along the direction of tectonic transport during … WebAs nouns the difference between foliation and lamination is that foliation is the process of forming into a leaf or leaves while lamination is the process of laminating, joining together thin layers. Other Comparisons: What's the difference? Delamination vs Exfoliation
WebFirstly, the crenulation must be analysed to determine the initial foliation, termed S 1, and the overprinting subsequent foliation. The intersection of these two planes forms an intersection lineation. This intersection lineation, L 1-2 may approximate the plunge of F2 interference folds . Weblineation: a linear fabric; typically defined by either linear minerals, such as hornblende, or stretched grains, such as quartz. Rocks with purely linear fabrics are called L tectonites and form by a constrictional deformation (prolate strain ellipsoid). ... foliation: a planar fabric; typically defined by platy minerals such as mica or ...
