Abstract: Based on a novel application of an archimedean type pairing to the geometry and deformation theory of $ K3$ surfaces, we construct a regulator indecomposable $ K_1$-class on a self-product of a $ K3$ surface. In the Appendix, we explain how this pairing is a special instance of a general pairing on precycles in the equivalence relation defining Bloch's higher Chow groups.
