Abstract

Abstract

In the 1:50000 mapping pilot projects, taking the surficial geological mapping of Shengcitang Town as an example, the building of the 3D model of this area is studied.15 NW trending geological routes are arranged according to the remote sensing image. The characteristics of superficial deposits within the depth of 3~4 m areare revealed by Eijkelkamp groove drilling. The work flow with DSI as the key technology of 3D superficial depositsmodel building is introduced. The groove drill core description is quantified as spatial attributes of grain size. Then, geological marker horizons are established based on the drill core. The 3D grid model with grain size attributes is constructed by interpolating the grain size of all cores, and the changes of vertical lithofacies is studied by taking an example of the 3D profile AA' with northwest strike.In order to study the changes of vertical lithofacies, taking the river facies layer after removing agricultural soil as an example, combining with the geomorphological characteristics, surficial lithologic and lithofacies boundaries in study area are outlined.The research suggests that 3D surficial deposits model holds significant value to regional geological survey, geological map drawing, lithology and lithofacies boundaries outlining and Holocene quaternary geology research. This model also can be used in environmental geological research like shallow groundwater antipollution, soil pollution problems, etal.
