The occurrence of shingling in. long range refraction records often makes the task of the seismic interpreter heavier, especially when several refractors are encountered and the velocity contrasts are small.
The explanation of the phenomenon given by the existing literature is examined and the theoretical results are compared with the observed data on field records.
In field seismograms shingling must be separated from the effect of geological structures or lateral discontinuities.
If an appropriate analysis of shingling is possible, this phenomenon can be related to the type of refracting layer, being a useful tool to a qualitative approach.
On the other hand the implications of shingling are examined on the side of the geometrical interpretation
