""'Helminthopsis " "'is the ichnogenus of a type of trace fossil that is found preserved on the bedding planes of fine-grained sedimentary rocks.
32.
The reef extends from Tennessee to Quebec and bedding planes now dip slightly to the north, revealing sequences of horizons in exposed rock.
33.
Narrow quartz veins, found along fractures in the diorite and along bedding planes in the shale, contain most of the high grade gold ore.
34.
It is thought that the Chuckanut Formation shoreline was of riverine environments combined with a large scale " bedding plane " of material deposition.
35.
When the ore forms a blanketlike body along the bedding plane of the rock, it is commonly called a "'manto ore deposit " '.
36.
Pleistocene-to Holocene-age landslide deposits are widespread throughout the Simi quadrangle, especially in the finer grained Tertiary sedimentary units where bedding planes are dip slopes.
37.
Tam Cung is a large phreatic fissure cave that developed in the bedding planes of the limestone dividing the fissure cave into three chambers.
38.
The increases in pore water pressure and in formation stress combine and affect weaknesses near the hydraulic fracture, like natural fractures, joints, and bedding planes.
39.
These planes or weakened areas allow the intrusion of a thin sheet-like body of magma paralleling the existing bedding planes, concordant fracture zone, or foliations.
40.
In all but one case, the landslides involved Quaternary material, the exception being a slide that was controlled by bedding planes in a Permian limestone.
