This video is intended for students in the common core of Geology, or any other interested public (high school students for example). It explains in a simplified way what stratigraphic logs are (also called stratigraphic columns / lithostratigraphic), their usefulness and the important elements that must be present on a log. The main information is the lithology, detailed in the form of representative figures.
This video was uploaded by Ms. Ruault-Djerrab, a teacher at the University of Guelma in Algeria.
Video highlights:
from 0:07: Definition.
from 2:50: Some examples of stratigraphic logs.
ERRATUM:
Around the 4th minute, in the second example of stratigraphic log, I take the sandstone layer as an example, saying that it is very thick because it is resistant: be careful, it is not about the thickness but of course of the WIDTH (same remark a little further for the marls, characterized by a low WIDTH because they are fragile rocks).
