However, bedding surfaces that have previously been rotated fall in either the shortening or the extension field of the strain ellipsoid, and are therefore more susceptible to folding and/or boudinage.
Determination of finite strain in bedding surfaces using sedimentary structures and trace fossils: a comparison of techniques.
The trackway lies 13 m downdip along the same bedding surface as that of an ancestral horseshoe crab (Metz, 2000), and approximately 1 m stratigraphically higher in the section than the trace fossils Rusophycus and Cruziana described from the same location by Martino and Zapecza (1978).
This is a convincing interpretation for this trace, as it occurs in close proximity and along the same bedding surface as a previously recorded ancestral horseshoe crab (Metz, 2000).
The think-bottomed receiver is also stiffer and provides a better bedding surface
Another technique is to use an aluminum skeletal structure around which the stock is laid, serving as a metal-to-metal bedding surface
for the barreled action.
The conclusion that the environment would have been poisonous is derived from geochemical data, "but the bedding surfaces
where these fossils were found represent moments of geological time during which free oxygen was available and conditions were favorable.
Arranged as clusters on bedding surfaces
of fine grained volcanic tuff, these structures are believed to have been originally composed of calcite.
Ashlar: Stone that has been cut at the quarry to produce relatively smooth, flat bedding surfaces
that stack easily.
