RAVAM provides solutions for both archaeological research and geological prospecting, delivering valuable insights for uncovering the past and mapping subsurface resources. 

RAVAM for Geological Prospecting

Mapping Subsurface Resources 

Expanding Exploration Horizons

RAVAM's capabilities extend beyond archaeology to encompass geological prospecting, offering advanced tools for mineral exploration, resource assessment, and understanding subsurface geological structures. 

Multi-Method Integration for Comprehensive Understanding

RAVAM integrates UAV-based Transient Electromagnetic (TEM) soundings with magnetic and gamma-spectrometric surveys to provide a comprehensive understanding of subsurface geology. This multi-faceted approach results in a more accurate interpretation of geological features and their potential for hosting valuable mineral resources. 

UAV-TEM Soundings

RAVAM's UAV-TEM system utilizes a lightweight inductive sensor towed by a multirotor UAV. This sensor measures the electrical conductivity of the subsurface and can penetrate to depths of over 300 meters. 

This deep penetration capability makes the system highly suitable for exploring deep-seated mineral deposits. 

Magnetic Surveys

RAVAM's magnetic surveys utilize sensitive magnetometers to detect variations in the Earth's magnetic field, which can be associated with different rock types and mineral deposits. 

Gamma-Spectrometric Surveys

RAVAM utilizes gamma-spectrometric surveys to measure the natural radioactivity of rocks and soils, assisting in the identification of areas potentially rich in uranium and other radioactive minerals. 

Refining Geological Understanding and Targeting Mineralization

RAVAM helps refine existing geological maps by accurately identifying boundaries between different rock formations, mapping fault zones, and detecting areas with potential for mineralization. 

*Case Study: Uranium Exploration
RAVAM solution was successfully deployed to delineate the boundaries of a uranium deposit located in a complex geological setting. This case study demonstrates the system's effectiveness in prospecting for hidden or "blind" ore deposits.

RAVAM for Archaeology

Non-Destructive Investigation of the Past

Preserving the Past

RAVAM utilizes non-invasive geophysical techniques, minimizing the need for disruptive excavations, thus preserving the integrity of sensitive archaeological sites. 

Precise Identification and Mapping

RAVAM employs proven methodologies, including terrestrial and UAV-based magnetic surveys, along with electrical resistivity tomography (ERT), to accurately identify and map archaeological features. 

Magnetic Surveys (Terrestrial and UAV-based)

RAVAM utilizes highly sensitive magnetometers to measure subtle variations in the Earth's magnetic field caused by buried archaeological features. 

Electrical Resistivity Tomography (ERT)

RAVAM incorporates ERT to measure variations in electrical resistivity within the subsurface. These variations often correlate with buried structures, features, and differing soil compositions. ERT is particularly effective in detecting remnants of ancient structures like furnaces, which exhibit distinct resistivity signatures. 

Visualizing the Subsurface in 3D

RAVAM employs sophisticated 3D inversion software to process and analyze the collected geophysical data, generating detailed 3D models of the subsurface that highlight the spatial distribution of magnetic and electrical properties. 

"CRGSoft" Software

RAVAM leverages the advanced capabilities of the "CRGSoft" program, which uses remanent vector scanning and elastic network techniques to accurately pinpoint the location of archaeological objects within the 3D model.
