1. Map sales:
2. Journals and publications for sale:
3. Laboratory services:

Laboratory:

The function of the chemical laboratory is to do analysis of a wide range of geological material as well as research and development of new analytical techniques. Currently most chemical analyses are carried out using Atomic Absorption Spectrophotometer (AAS) after nitric acid digestion.

Activities

(i) Water quality analysis of groundwater samples.
(ii) Chemical analysis of rocks, soil and stream sediment samples from exploration and mapping programmes.
(iii) Preparation of thin and polished sections for mineral identification.
(iv) Provision of analysis / identification of minerals to interested parties.

Mapping

Geological mapping is an ongoing activity of the department.

The geological mapping section is currently revising the geological and structural maps of the country with the view of updating them.

The country has been mapped at the following scales:

All these publications are available in analogue format

Seismology:

The department is presently involved in a project that will help improve the capturing of seismic data and minimize the reliance on information sourced from the Council for Geoscience in South Africa (CGS) and the United States Geological Survey (USGS). Five seismic stations have been strategically placed across the country in Motshane, Mzimpofu, Gege, Lavumisa and Mananga. The data will not only assist the country but will also contribute to improved regional data collection.
