This article continues a description of the methodological and technological aspects of the constructing physical-geological models of oil and gas promising regions with a help of the INTEGRO GIS tools. The methods are described on the materials of studying the deep structure of the Yenisei-Khatanga regional trough (YKRT).
The first part of the article covered the stages of analysis of the spatial distributions of potential fields and integrated regional profile geophysical data. The present, second, part of the paper describes the process of the YKRT three-dimensional density model construction, which is based on the results of the previous analysis.
