The contacts are tectonic in places with prominent slickenside features and cataclastites.
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.
Stable oblique macropores were observed (bordered by lenticular peds with slickenside surfaces) in a soil profile pit at this site, starting at around 60 cm and continuing over 1 m in vertical depth.
The claystone of the overlying Lontova Stage is disturbed by numerous slickensides increasing upwards in number.
clay throughout the profile except for thin surface layer; they crack when dry and have slickensides or lenticular peds.
No evidence of fault movements such as strain indicators or slickensides has been observed in any breccia exposure.
Drill hole three cut a 86 metre wide, strongly fractured and altered graphitic-pyritic pelite unit containing fracturing, grey clay and slickensides.
In addition, how could slickensides (polished and smoothed striations made in hard rock by fault action), fault gouge and breccias (pieces of angular rock and earthy material along faults), and the sharply offset rock layers along faults (rather than layers slumping into faults) have formed in rock that was still soft?
The process is revealed by features such as slickensides, wedge-shaped peds and wide, long cracks.
