volcanoes, mineralization, and oil accumulation) that occurred during the evolution of the earth is essential not only for understanding the “abrupt changes in the evolution of the earth”, but also for an in-depth understanding of the co-evolution of material-life-environment of the livable ear...
map (1:1000 000) was also used. The surficial geology map is based on 1:50 000 scale maps produced by the Quebec DNR specifically for this regional assessment and on 1:62 500 scale maps for VT and 1:250 000 for NY. The bedrock map describes the main lithologic assemblages ...
First, using a variety of computer language mixed programming, and development of land-use master planning computer-aided system, to achieve the Chinese display and map input and output of the Chinese characters (Enman, 1990). Second, using the system theory and system engineering method, ...
Secondly, according to the number of geological disasters and the slope abrupt change of cumulative frequency curves under each index, the assessment index factors are graded into different states. Finally, the grid data model is established to carry out regional geological hazards assessment by using...
A new map of the Kunene Complex, based on our interpretation of processed remote sensing data and ground-truthing. The spatial distribution of the Karoo and Damara supergroups in Namibia (included here in the post-KC capping units) is from the Geological Survey of Namibia 1:250, 000 map. ...
This work is very time consuming and can account for a significant part of the expert's working time [97]. In recent years, the multiplication of new techniques has made it possible to quickly acquire more information to map phenomena and to obtain precise information on topography or on the...
