Main genetic types of sea mounts

Abstract

Three main types of the sea mounts are identified on the basis of geological, geophysical and geomorphic features, i. e. volcanic, volcano-tectonic and tectonic sea mounts. Main features of each type are described and distribution according to main oceanic structures is shown.

Most widespread type are volcanic sea mounts, especially in the Pacific. Several kinds of distribution (in connection with tectonic structures) may be distinguished, i.e. linear, areal, cluster-like, annular and sporadic. The volcano-tectonic mounts are noted to be typical for mid-oceanic ridges and transform faults. Tectonic mounts are mostly spread over peripheral parts of oceans and seem to be result of vertical and horizontal movements. Sea mounts types and their distributions give evidence for tectonic unhomogenity of the: Earth's oceanic areas.
