Abstract
In this paper we study a linearized inverse reflection problem for the elastic wave equations. We derive the relation between polarization sets of reflected waves and wavefront sets of the Lamé parameters. The result does not require the `no caustics' assumption on the incident wavefront. The use of polarization sets of vector-valued distributions is crucial in our proof.
