FAQ
Frequently Asked Questions
Geological mapping is the process of recording rock types, structures, and formations on the Earth’s surface to create a geological map for planning and analysis.
Geological maps help in understanding local rock types, fault zones, and terrain stability—especially for construction, mining, and land-use planning in Malaysia.
We offer detailed mapping, structural mapping, stratigraphic mapping, preliminary surveys, terrain classification, and mineral exploration mapping.
It is used in construction site planning, slope stability analysis, mineral resource exploration, infrastructure design, and academic research.
Preliminary mapping gives a broad overview of the geology, while detailed mapping provides in-depth information on rock types, faults, and formations at a finer scale.
Stratigraphic mapping focuses on the layers and age of rocks, while structural mapping highlights faults, folds, and stress-related features in the rocks.
Yes. Terrain and structural data from geological mapping are used to identify slopes at risk of landslides, especially in hilly and high-rainfall areas.
It helps identify rock units, alteration zones, and geological structures that may host mineral deposits, guiding exploration drilling and sampling.
Common tools include GPS devices, geological compasses, topographic maps, field notebooks, GIS software, and sometimes drones for terrain analysis.
Geotechnica offers professional geological mapping in Malaysia with accurate fieldwork, GIS integration, and terrain-based recommendations for engineering, mining, and environmental projects.
