krockzoner

Krockzoner is a geophysical instrument and data-analysis framework designed to identify and delineate rock zones with contrasting lithology and mechanical properties. It integrates multiple sensing modalities to produce high-resolution maps of subsurface rock types.

The name combines "rock zone" with a distinctive "k-" prefix used by the developing lab.

The krockzoner combines seismic refraction, electrical resistivity tomography, and ground-penetrating radar, along with borehole and surface gravity measurements, feeding a machine-learning model to classify rock types and boundaries.

Developed by the GeoTech Research Consortium in the early 2010s; field validation in basaltic terrains in 2016; newer versions improved with drone deployment.

Used in mining, civil engineering, geothermal assessment. Advantages: speed, non-invasiveness, high resolution; Limitations: requires calibration, depth limits, weather/moisture sensitivity.

Variants include krockzoner-Scout, -Drone, and -Pro, with increasing autonomy and depth reach. The technology is being incorporated into regional geoscience programs and mining plans.
