For thin, highly resistive layers, the software can resolve the product of resistivity and thickness (transverse resistance), but not the individual values.
Handles DC Resistivity (Schlumberger, Wenner, Dipole-Dipole, Pole-Dipole, Pole-Pole), IP (Chargeability, Phase), MT, and EM data.
IX1D v3.50 is widely deployed to locate freshwater aquifers. By mapping low-resistivity zones, hydrogeologists can separate dry sands from water-saturated gravels and pinpoint clay barriers that act as aquitards. Bedrock Mapping interpex ix1d v350

While newer versions of IX1D exist (e.g., IX1D v4), the v350 release holds a special place for several reasons:
Features mathematical modeling for deeper structural investigation using apparent resistivity and impedance phase. Key features in v350 include: Before constructing bridges
The software inverts apparent resistivity (and optionally IP chargeability) data to produce a layered-earth model: layer thicknesses and true resistivities. Key features in v350 include:
Before constructing bridges or high-rises, engineers need depth to competent layers. IX1D v350 identifies layers of high resistivity (dry sand/gravel) vs. low resistivity (clay, water-saturated silt). Version v350’s ability to output layer thicknesses with standard deviations directly informs geotechnical design.
