The faults are a combination of dip slip and strike slip faults, and are well displayed because they are oblique to the bedding planes; they are often mineralized with quartz and have traces of slickenside striations along the walls.
Due to thrusting of this anticline the southwestern limb of Muzaffarabad anticline is mostly crushed showing fault breccia, mylonite, gouge and slickenside of bed rocks.
peak] and MAF for Zumaya impact layer, when compared to Agost and Caravaca, are probably due to the low preservation and fragmentary state of the impact layer in the former section, which probably means that the impact layer sample is mixed with more spurious material and possibly with authigenic high coercivity phases precipitated in the bottom calcite slickenside.
The contacts are tectonic in places with prominent slickenside features and cataclastites.
Slickenside (Chapters 2, 14)--Polished surfaces on blocks of soil formed by the blocks sliding past one another as occurs in Vertisols.
A sharp, well-defined slickenside clearly separates the vein from the country rock, forming the smooth east wall of our tunnel.
Tiny scales on slickenside surfaces were found on the 800 level (244 m) of the Lexington mine (JL).
Most authors concur, however, that the primary pathway of drainage in clay soils is preferential flow through soil cracks, slickenside, and biopores (Booltink 1995; Bronswijk et al.
Based on slickenside striations the granitoid rocks appear to be thrust eastward over the metasedimentary rocks.
It is worth to stress that at the continuation of this zone towards the west, numerous blocks of sandstone occur in the soil with distinct slickenlines on slickenside surfaces perpendicular to the bedding planes.
