Abstract
Linearized approximations for reflections coefficients<br>used for AVO analysis are not suitable to determine<br>density contrasts. Second order approximations of<br>converted waves reflected amplitudes are necessary to<br>estimate density and the lithological indicators associated<br>to it. We present explicit second order expression<br>for reflected and transmitted amplitudes of converted<br>waves in isotropic media which can be used to<br>extend AVO analysis accurately to converted waves.
