lineation उदाहरण वाक्य
उदाहरण वाक्य
- This hypothesis suggests that the magnetic lineations on Mars are analogous to the banded magnetic anomalies in the North American Cordillera on Earth.
- In such a case the lineation may not be as obvious in plan and may require measurement as a rake upon a planar surface.
- Knowledge of the now subducted Izanagi Plate is limited to Mesozoic magnetic lineations on the Pacific Plate that preserve the record of this subduction.
- These lineations, which were likely created by subglacial erosion, form a well-defined en echelon topography that characterize the bottom of Lake Ontario.
- Although no spreading center has been identified, a map of the magnetic anomalies on Mars reveals that the lineations are concentric to the south pole.
- Because of the constraints imposed by simple shear, displacement is assumed to occur in the foliation plane in a direction parallel to the mineral stretching lineation.
- Stretching lineations may also manifest as linear features upon pre-existing surfaces such as foliations within shear zones ( see image at right, below ).
- The flanks of the SEIR are dominated by fracture zones perpendicular to the ridge and gravitational lineations oblique to the spreading direction and sometimes zigzag-shaped.
- In this case, the lineation may be measured from the horizontal as a " rake " or " pitch " upon the surface.
- Rake is measured by placing a protractor flat on the planar surface, with the flat edge horizontal and measuring the angle of the lineation clockwise from horizontal.
