Morpho-structural analysis and modelling
Identification of ore-bearing structures and reduction of the search area
The use of digital morphometric modelling and lineament analysis of the terrain identifies morphostructures, sediment migration pathways and mineralisation zones even before exploration work is carried out.
What issues faced by subsoil users are addressed during the morphostructural analysis and modelling stage?
01
Insufficient accuracy of the source geological data
We create a digital terrain model and subsequently identify morphostructural features by reconstructing the stages of terrain formation, thereby highlighting both obvious and hidden structural boundaries, the relative amplitudes of vertical movements, and other morphological characteristics of potential mineralisation and accumulation zones.
02
The challenges of conducting research in difficult and remote locations
We carry out research without needing to go out into the field — even in areas with challenging terrain and dense vegetation — using morphometric modelling and analysis based on remote sensing data.
03
Traditional methods overlook ore-bearing zones
We carry out lineament analysis and modelling using radar satellite data — identifying hidden residual, linear and ring-shaped structures, the degree of denudation, and the pathways of material transport and accumulation that are inaccessible to standard methods.
04
High costs — uncertainty at the start of the search
We pinpoint areas of mineralisation and reduce the scope of exploration drilling, thereby conserving resources and improving the accuracy of our forecasts.
How does the process of morphostructural analysis and modelling work?
We identify promising areas, refine structural boundaries and predict mineralisation zones at the early stages of geological exploration using digital morphometric modelling based on radar satellite imagery.
The methodology comprises a series of stages:
- Geomorphological analysis — gathering preliminary information on the structure of the relief and identifying general patterns in its development using a range of geomorphological models;
- Reconstruction of landform development — modelling of past topography, which provides valuable information on the morphostructural composition of the area, the nature of stratigraphic sequences and the relative intensity of modern crustal movements;
- Modelling of residual structures and the degree of denudation — a stage that makes it possible to identify hidden residual structures as the sources of primary ore deposits, as well as to determine the conditions under which placer deposits formed, based on the extent of denudation;
- Linear analysisз — identification of linear and ring-shaped landforms using semi-automated and automated algorithms, followed by their interpretation;
- A comprehensive analysis that integrates all the models obtained — the stage at which the identified morphostructures, linear zones and other landform features are superimposed onto existing geological data for joint interpretation.
The result is that the client receives a morphostructural map highlighting structural features that indicate potential mineralisation and the accumulation of valuable components, enabling the identification of promising areas for further exploration.
Focus on the most promising opportunities — without unnecessary costs
Morpho-structural analysis identifies hidden structural features and focuses resources on areas with a high probability of mineralisation.

Key challenges faced by subsoil users and ways to address them
One of the most common issues at the early stage of any project is the limited availability, low precision, and coarse resolution of initial data. Traditional early-stage methods frequently rely on sparse, point-based ground measurements that fail to provide a complete, objective spatial view of complex surface geology. We address this limitation by applying morphostructural analysis based on Digital Elevation Models (DEMs) derived from advanced satellite radar data. Our approach ensures continuous spatial coverage and seamless evaluation across the entire project area, delivering complete data integrity and identifying subtle structural features.
Another widespread challenge occurs when traditional field methods miss mineralized zones, particularly when concealed beneath thick overburden or cover sequences. We overcome this limitation because landforms retain expressions of deep-seated geological structures, manifesting at the surface even through un-consolidated cover. By deploying morphometric analysis, we reconstruct landscape evolution stages and delineate concealed structural controls.
The financial dimension is always central: high upfront exploration expenditures are further compounded by early-stage technical uncertainty. Morphostructural processing serves as a powerful tool to mitigate this financial risk. By precisely pinpointing potential mineralization targets, we reduce the footprint requiring intensive, high-cost field surveys by a factor of several times. Capital is thus deployed into targeted evaluations of high-potential targets rather than blanket coverage, substantially boosting overall economic efficiency and forecasting confidence.
Furthermore, many prospective areas feature challenging operational environments — high-altitude terrain, wetlands, or dense vegetation cover making field logistics exceptionally difficult and expensive. Our methodology enables comprehensive spatial evaluations prior to field mobilization. Leveraging morphometric modeling techniques delivers high-confidence results even for the most remote and inaccessible regions, optimizing both project timelines and capital expenditure.
Methodology for conducting the analysis
The morphostructural analysis process is a multi-stage workflow initiating with data collection and processing. We utilize satellite radar imagery to generate high-resolution Digital Elevation Models (DEMs) tailored to required spatial accuracy. These baseline datasets are then used to construct a suite of derivative surface models.
The next phase involves a regional geomorphological evaluation of the target area. Serving as an initial baseline review, its primary objective is to acquire fundamental insights into landform structure and establish general landscape evolution patterns. During this phase, various derivative models are generated — such as surface flow direction, drainage network and watershed models, and surface slope maps — providing the essential foundation for subsequent, in-depth morphometric and structural studies.
Next, palaeo-landscape reconstruction is performed. Utilizing morphometric analysis techniques to model palaeo-relief provides a unique approach to un-covering concealed geological structures. This enables the prediction of potential mineralized zones that cannot be identified from modern surface topography alone.
A critical stage involves modeling residual structures and denudation depth. This analysis uncovers concealed residual structures acting as hard-rock ore sources, while denudation magnitude evaluation defines the conditions for placer deposit formation.
The subsequent phase comprises lineament analysis. Utilizing semi-automated and automated algorithms, we identify all linear and circular topographic features. Furthermore, correlating lineament detection with landscape evolution stages enhances the precision of fault zone mapping. The unique value of our methodology lies in differentiating fault formation timing, which provides a clearer understanding of tectonic evolution.
The final phase encompasses an integrated evaluation synthesizing all generated models. Identified morphostructural units, linear zones, and other topographic features are cross-referenced with available geological, geophysical, and geochemical datasets. As a result, we construct a unified, multi-layered GIS framework that moves beyond raw data interpretation to achieve high-precision target generation and prioritization forfollow-up exploration campaigns.
Final deliverables for the Client
As a result of the work carried out, the client receives a comprehensive product that provides a qualitatively new level of understanding of the area’s geology. A key element is a set of thematic maps: a map of lineaments and ring structures, a map of morphostructural zoning, a map of residual landforms and the degree of denudation, a map identifying prospective areas, and others. These materials are accompanied by all derivative products in formats compatible with common GIS packages.
The key outcome is the precise identification of promising areas for further exploration. Rather than an abstract ‘prospective area’, the client receives specific targets — local structures, fault zones and blocks — which are highly likely to be associated with mineralisation. This allows the programme of subsequent fieldwork to be optimised, focusing it on the study of key targets, thereby significantly reducing the time and financial costs of the exploration and appraisal phase and minimising the economic risks of the project as a whole.
