Due to tectonic inter-bed sliding, calcite slickensides 1-2 cm thick have deposited both at the bottom and at the top of the clay-rich interval, irregularly altering the basal part of the K-T boundary marly clay.
Where the development Of [S.sub.b] is more uniformly intense, [S.sub.a] is preserved only within the [S.sub.b] lithons, forming a pronouncedly curved surface (turning into parallelism with [S.sub.b]), and showing the strongest development of the slickenside lineation [L.sub.s] (Fig.
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.
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.
