All tyrannosaurid and hadrosaur bones lie horizontally within a 20 cm thick blocky, green claystone with occasional calcitic nodules and vertical to subvertical burrows. |
|
The fourth, previously unobserved, type of flow system is provided by subvertical quartz-barite veins with open fractures and vugs. |
|
The angle of view is subvertical, inclined at 10°, to avoid recording the ballast in the photographic field. |
|
They are generally cut into more or less regular successive steps with subvertical walls. |
|
It is an east-west striking, subvertical intrusive body, approximately 3300 metres long, 150 to 450 metres wide and at least 900 metres deep. |
|
The free and often coarse gold is hosted in quartz veins associated with narrow, S-E trending, subvertical shears. |
|
Specialists then realized that the 'Cylindre' is in fact a thick layer of subvertical schist and dark sandstone which has nothing of a cylindrical form. |
|
The zone is tabular in shape, subvertical and strikes northwest. |
|
The geology consists of a complex assemblage of felsic tuffs and felsic to intermediate fragmental intrusives trending east-west, with a subvertical dip. |
|
Despite the broadly circular and subvertical orientation of the strata around the collar of the dome, the structure is complicated on a smaller scale by both folding and concentric and vertical radial faults. |
|
This association, described by Molinier in 1958, forms belts in the photophilous biotopes where there is strong wave action, and whose rocky substratum is subvertical. |
