THE USE OF A MORPHOSTRUCTURAL ANALYSIS FOR STUDYING THE TECTONIC STRUCTURE OF THE NIZHNE-ANADYR DEPRESSION

Abstract

The use of a morphostructural analysis while prospecting for oil- and gas-bearing structures in the Nizhne-Anadyr Depression gives positive results. A close examination of the linear elements of relief and drainage system (megafructuring), with the use of geophysical data, shows that plutonic (intrusive) structures of the sedimentary mantle and the basement have their expession in the present relief of the Depression. Data obtained by the morphostructural analysis helps to define inherited and superimposed structures of the sedimentary mantle.
