G3Dv2_0317, fractures in base Fm of Opglabbeek

This layer shows the position of the modelled fractures in the base of the Opglabbeek Fm. Most fractures occur in the deep subsoil, with the number of fractures continuing upwards in stratigraphy systematically decreasing depth. There are thus a significant number of fractures in the Devoon and Carboon, which are already lower in the Krijt, in the Paleogen and Neogen, and only a few major fractures (especially in and around the Roerdalslenk) are still present in the Quartair, linked to deep (re) fractures. The Geological 3D model was drawn up under the Flemish Government’s management agreement with VITO, known as VLAKO, on behalf of the Department of LNE – Land and Soil Protection Division, Subsoil, Natural Resources.本图层展示了奥普格拉贝克组（Opglabbeek Fm）底部的模拟裂缝分布位置。绝大多数裂缝发育于深部地下地层中，随着地层向上（埋藏深度逐渐变浅），裂缝数量呈系统性递减趋势。因此，泥盆系（Devoon）、石炭系（Carboon）、白垩系（Krijt）下部、古近系（Paleogen）及新近系（Neogen）中均存在大量裂缝；而第四系（Quartair）中仅存少量大型裂缝（尤其集中于罗尔达尔槽（Roerdalslenk）及其周边区域），此类裂缝与深部（再生）裂缝相关。本地质三维模型是在法兰德斯政府代表LNE部门——土地与土壤保护司、地下资源与自然资源分部，与弗拉芒技术研究院（VITO）签订的名为VLAKO的管理协议框架下编制完成的。
