Abstract

This paper presents results from a study of a monogenic cone situated in the Khalaktyrksky beach, Avachinsky, Kamchatka. We used georadar surveying methods to reconstruct the paleo-relief of the monogenic cone and to estimate the thickness of the overlain sediments. Discontinuities are marked by higher values of the spatial distribution for subsoil carbon dioxide in combination with the deformations as detected by the georadar. The data provide evidence of a long-continued degassing from the lavas of the monogenic cone and of activity shown by the discontinuities in the Avachinsky graben of the Malko–Petropavlovsk zone of transverse dislocations.
