Amplitude Versus Offset methods make use of different domains to display rock properties and seismic amplitudes. A transformation from one domain to another will in general either create a trend or change an existing trend. Trends created by a transformation do not add any information about properties of the input data and I call these transformation trends. Whereas a strong transformation trend results when displaying seismic data in the Intercept Gradient domain, a trend is also created, though a much weaker one, when converting compressional and shear velocities and density to the same Intercept Gradient domain. Points and trendlines transfer in different ways. If a trend seen in one domain is (for example) a lithology trend, such as the trend often seen in crossplots of V and V, then a trend resulting from the same data in another domain will be a lithology trend.
