| Abstract: | The regional geological survey project of 1∶250 000 Aba sheet has got progress in multiple division and correlation of Triassic strata, Aba basin evolution from Neogene to Quaternary, tectonic structure and activity study of major tectonic zone. In this project, basing on detailed geological survey along the first stage of the western route project of South-To-North Water transfer scheme, a series of geological maps and profiles of water transfer route had been compiled, which were favorable for optimization of water transfer route, and these provided experience on expanding service of regional geological survey. In this project, digital mapping system had been applied in regional geological survey, the feasibility, effectiveness and suitability had been discussed in this pilot application, the working process and methods of digital regional geological survey which was suitable for engineering and environmental geology survey had been established. These increased the application of achievements from regional geological survey. |
