The layering construction of the three-dimensional (3D) geological model for Wudalianchi volcanic area, Northeast China
Xue Jiang, Ranran Li
TL;DR
Researchers created a 3D geological model of a volcanic area in China to better understand its structure and support resource management.
Contribution
A novel layered approach using UGrid and DEM data to build a reliable 3D geological model in data-scarce volcanic regions.
Findings
The volcanic area's strata were divided into four layers based on eruption cycles.
The 3D model successfully visualized complex stratigraphic distribution and was validated by spring formation mechanisms.
The model supports sustainable use of groundwater, geothermal, and mineral resources in the region.
Abstract
Establishment of geological model in volcanic area is challenging owing to lack of borehole data and the effect of volcanic activity on rock distribution. Taking full advantage of the existing complete volcanic landforms and recognized for seven eruptive cycles in Wudalianchi volcanic area, here we apply a layered approach to build geological models for meeting rapid development of agriculture and understanding the evolution of regional geological structure. Based on the volcanic eruption cycle, the stratas in Wudalianchi volcanic area are divided into four layers. UGrid (unstructured grid in GMS) is used combining with DEM data to hierarchically build 3D geological structure model of volcanic area, which realize the visualization of regional stratigraphic distribution, and the reliability of the model is verified by the formation mechanisms of different types springs. The stratified…
