Reconstructing the Palaeo-Environment of the Ancient City of Charax Spasinou
- From its foundation to its heydays as trading hub and to its final abandonment, the history of Charax Spasinou was intimately connected with the evolution of the river systems of the southernmost part of the Mesopotamian plain and the shoreline of the Persian Gulf. This ongoing research, which is part of the Charax Spasinou Project of the Universities of Konstanz and Manchester supported by the German Research Foundation and the Culture Protection Fund of the British Council, aims to reconstruct the evolution of the landscape and palaeoenvironment around the capital of Mesene, by combining evidence from remote sensing data and geological coring. Here, results from the analysis of satellite imagery and a preliminary field campaign carried out in 2018 will be presented. It will be demonstrated that a combined geological and archaeological survey in the wider hinterland of Charax allows an accurate reconstruction of the ancient watercourses and the landscape of Mesene, in which the capital was the nodal point for nearly a millennium.

Soil Settlement and Uplift Damage to Architectural Heritage Structures in Belgium: Country-Scale Results from an InSAR-Based Analysis
- Soil movement may be induced by a wide variety of natural and anthropogenic causes, which are detectable in the local scale, but may influence the movement of the soil over vast geographical expanses. Space borne interferometric synthetic aperture radar (InSAR) measurements of ground movement provide a method for the remote sensing of soil settlement and uplift over wide geographic areas. Based on this settlement and uplift evaluation, the assessment of the potential damage to architectural heritage structures is possible. In this paper an interdisciplinary monitoring and analysis method is presented that processes satellite, cadastral, patrimonial and building geometry data, used for the calculation of settlement and uplift damage to architectural heritage structures in Belgium. It uses processed InSAR data for the determination of the soil movement profile around each case study, of which the typology is determined from patrimonial information databases and the geometry is calculated from digital elevation models. The impact on the historic structures is calculated from the determined soil movement profile based on various soil-structure interaction models for buildings. The resulting damage is presented in terms of a numerical index illustrating its severity according to different criteria. In this way the potential soil movement damage is quantified in a large number of buildings in an easily interpretable and user-friendly fashion. The processing of InSAR data collected over the previous 3 decades allows the determination of the progress of settlement- and uplift-induced damage in this time period. With the integration of newly acquired and more accurate data, the methodology will continue to produce results in the coming years, both for the evaluation of soil settlement and uplift in Belgium as for introducing related damage risk data for existing architectural heritage buildings. Results of the analysis chain are presented in terms of potential current damage for selected areas and buildings.

Unfolding veined fold limbs to deduce a basin’s prefolding stress state
- Tectonic structures that developed prior to folding, such as pre- and early-kinematic veins, hold valuable information on the stress state of the paleobasin in which these early structures formed. To derive the parental orientation of these prefolding brittle structures, folds need to be ‘unfold’. A fold restoration methodology is presented in which fold limbs, and structures they contain, are rotated back to their depositional horizontal position by removing the tilt of the fold hinge line and the dip of individual fold limbs. The method is applied on quartz veins emplaced in folded Lower Devonian sandstones from the High-Ardenne slate belt (Belgium, Germany) and allowed deducing NW-SE opening when the Ardenne-Eifel Basin was at maximum burial depth (early Carboniferous). This exercise can be used in structural geology classes to teach how to rotate data using stereonet techniques hereby encouraging students in applying an unfolding strategy to derive information from prefolding structures.
