Abstract

Building a cross-border structural framework for the AOI and linking existing models to this framework. Framework will be derived from existing 2D and 3D models and geophysical data (aeromagnetic and gravity data) (Fig. 2). It is NOT the intention to build a 3D model for the AOI. It is about creating a coherent, structural backbone to which and via which models of different scale and resolution can be linked and connected (cf. Google maps). For this task there is a strong bi-directional link with GE4-HIKE. Task 3.2: Geomanifestations Doing a cross-border inventory of selected (harmonized) geomanifestations data indicative of fault activity, elevated geothermal gradients, fluid and heat flow, and tying these to the structural framework (Fig. 3). Resulting new insights will allow improving the structural framework. Geomanifestations of particular interest: • Seismic activity / seismicity • Variations in hydraulic head • Mineral springs and water chemistry at surface and at depth • Temperature anomalies at surface and at depth • Gas seeps (e.g. CH4, CO2) at surface and at depth • Ore deposits, including lead-zinc-copper deposits Task 3.3: Subsurface Management Making the geological information readily accessible, understandable and tailored to the regional needs of stakeholders and end-users (cf. EGDI) (Fig. 4). Examples of regional policy needs to be addressed: • Resource appraisal • Geohazard prediction/management • Sustainable subsurface use • Access to geological information Fig. 3: Examples of geomanifestations in the R2R study area.

Study area (AOI)
Geographic: Border regions between Belgium, The Netherlands, Germany, Luxembourg, France.
Geologic: Onshore southern North-Sea Basin, Roer Valley Graben, Variscan Front zone, western
Eifel area, and Upper Rhine Graben (Fig. 2).
Task 3.1: Structural Framework
Building a cross-border structural framework for the AOI and linking existing models to this
framework. Framework will be derived from existing 2D and 3D models and geophysical data
(aeromagnetic and gravity data) (Fig. 2).
It is NOT the intention to build a 3D model for the AOI. It is about creating a coherent, structural
backbone to which and via which models of different scale and resolution can be linked and
connected (cf. Google maps).
For this task there is a strong bi-directional link with GE4-HIKE.
Task 3.2: Geomanifestations
Doing a cross-border inventory of selected (harmonized) geomanifestations data indicative of
fault activity, elevated geothermal gradients, fluid and heat flow, and tying these to the
structural framework (Fig. 3).
Resulting new insights will allow improving the structural framework.
Geomanifestations of particular interest:
Seismic activity / seismicity
Variations in hydraulic head
Mineral springs and water chemistry at surface and at depth
Temperature anomalies at surface and at depth
Gas seeps (e.g. CH4, CO2) at surface and at depth
Ore deposits, including lead-zinc-copper deposits
Task 3.3: Subsurface Management
Making the geological information readily accessible,understandable
and tailored to the regional needs of stakeholders and end-users (cf.
EGDI) (Fig. 4). Examples of regional policy needs to be addressed:
Resource appraisal
Geohazard prediction/management
Sustainable subsurface use
Access to geological information

Objectives
Within context of Geoconnect³d (Fig. 1),WP3 -
Roer-to-Rhine (R2R) is one of two bottom-up case
studies to test and implement workflows to
facilitate:
Cross-border, cross-thematic evaluation of
geological resources and applications
Subsurface management and policy support for
the exploitation of georesources.
