Vertical variations in the orientations of sheathfolds are evidence that rheomorphism and welding can occur syn-depositionally.
2.
The 79 AD eruption of Mount Vesuvius produced the Pompeii Pumice which is an example of lateral and vertical variations.
3.
This means that the vertical variation of the electron's wavefunction, and thus a component of its energy, is quantized.
4.
These types of rocks are commonly formed in marine environments and the horizontal layering and vertical variation indicates marine transgression / metamorphosed shales.
5.
There are vertical variations in the grade of welding, some are only barely distinguishable from a lava flow except by the presence of clear edges around some clasts.
6.
However, in cases where the mean state is sufficiently simple, the vertical variations can be separated from the horizontal and several sets of shallow water equations can describe the state.
7.
The contemporary map should so depict the earth s surface that one can not only measure the horizontal positions of and distances between all points and localities, but also clearly distinguish vertical variations, from sea level to the highest summits ."
