Laboratories of Central Department of Geology
The CDG has high equipped petrographic laboratory with all the facilities from rock cutting, slicing and lapping into thin slicing to mineral, ledge rock or rock core sample identification. As the laboratory is equipped with high power polarizing microscopes and stereoscopes, the laboratory can also analyse petrography of aggregates, sediments and alkali-silica reactivity of various fine- to coarse-aggregates and rock samples.
Petrographic laboratory: Students are separating heavy minerals
The XRD laboratory is equipped with computer controlled, Bruker’s D8 advance defractometer with Diffrac plus software. It can be used to identify and find relative proportion of economic and deleterious minerals. Identification clay minerals has several applications in discovering hydrocarbons, engineering constructions, environmental management, earthquake hazard management, agriculture and land use planning, environmental interpretation.

Engineering Geological Laboratory
The Engineering Geological Laboratory is equipped with various testing machines such as triaxial machine, direct shear test machine, consolidation testing machine, Casagrande’s tools, oven, siever, etc. The CDG is upgrading this laboratory by adding various machines and tools such as sieve shaker, uniaxial compression machine, and a set of machines and tools for testing aggregates. Currently , the following laboratory facilities are available in the Engineering Geological Laboratory:
1. Water Content Determination
2. Organic Content of Peat or Organic Soils
3. Unit Weight (Density) Determination
4. Specific Gravity Test
5. Relative Density Test
6. Grain Size Analysis for both Coarse and Fine Soils
7. Atterberg Limits Test
8. USCS Classification of soil
9. Compaction Test by Standard Protractor and Modified Protractor methods
10. Hydraulic Conductivity (Permeability) Test
11. Consolidation Test
12. Direct Shear Test for Soil
Triaxial machine in CDG
It is equipped with GPR, Terrameter, Seismic refraction survey instrument, etc.
Laboratory of ore microscopy
This laboratory contains several specimens of ores, ore minerals and ore microscopes.
Computer room for GIS
The Computer Room is equipped with about 12 computers, one digitizer, one plotter, and various softwates such as Ilwis, AutoCad, CorelDraw, ArcView, ArcGIS and Dips.
Museum and specimens
The museum of the CDG has a collection of specimens of ore minerals, rock forming minerals, sedimentary rocks, metamorphic rocks and igneous rocks. It also has a huge collection of animal and plant fossils from the country and abroad.
