G3Dv2_0202, fractures in base Fm of Kattendijk and Kasterlee

This layer shows the location of the modelled fractures in the base of the Fm of Kattendijk and Kasterlee. 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.本图层展示了凯特登伊克地层（Kattendijk Formation）与卡斯特利地层（Kasterlee Formation）基底的模拟裂缝分布点位。绝大多数裂缝分布于深层地下土层中，且裂缝数量随地层向上（埋深逐渐变浅）呈系统性递减。泥盆纪（Devonian）、石炭纪（Carboniferous）地层中存在大量裂缝；此类裂缝在白垩纪（Cretaceous）下部、古近纪（Paleogen）及新近纪（Neogen）地层中亦有分布；第四纪（Quaternary）地层中仅存少量大型裂缝（尤以罗尔达尔斯伦克（Roerdalslenk）及其周边区域为甚），且这些裂缝与深层（再生）裂缝存在关联。本地质三维模型由佛兰芒政府代表LNE部门——土地与土壤保护司、地下土层与自然资源处，依据与弗拉芒技术研究院（VITO）签订的VLAKO管理协议编制完成。
