Intercept and Gradient[edit]

This article needs an explanation of the Intercept and Gradient concepts. It could also use a definition of the 4 basic classes of anomalous AVO responses. Hamsterlopithecus (talk) 14:34, 11 June 2010 (UTC)

I've reworked the introduction, added some background theory and I'm working on this now. Nwhit (talk) 15:11, 9 February 2012 (UTC)

Small errors in the Intro Diagram about the geometry[edit]

User:Nwhit has made an excellent diagram for the intro section of this article but it has 2 small errors. Other than that, it's all looking great!

  • The "offset" definition should probably be something like R_n-X_n. But I think it would be even more useful to just draw a double sided arrow showing the offset distance directly on the digram (above the common midpoint) and not on the legend. Something like this:


  • The angle shown on the diagram is not the angle of incidence, it is it's complementary angle. The angle of incidence if measured between the ray path the vertical.
