Abstract：Three-dimensional geological mapping is a pioneering job in frontiers without much experience.It is far more challenging to work out three-dimensional geological structure in a square area with certain scale for complex orogenic and metallogenic belts,where geophysical and drilling data are relatively limited.In this paper,we put forward a framework of the three-dimensional geological map-ping and visualization for bedrocks of orogenic belts based on our three-dimensional geological mapping practice in the northwest Kara-may,western Junggar.We emphasize that the basic data involved in visual modeling for a certain square area and scale are primarily based on the network of systematic surface geological sections and then the extension for the deep geological bodies which are based on geological-geophysical-drilling united constraints.With the combination of surface geological sections and geophysical/drilling data, three-climension geological texture from surface to certain depths at a certain confidence level can be traced.That is to say that three-dimensional numerical models of geological structures can be constructed by utilizing the rich data of classical “surface regional geological mapping”with the combination of geophysical/drilling data.
