Academic Activities

Library of CDG

Library of CDG (Plate 3) was established in 2006 after merging out from isolated collection corners of the department as well as of Nepal Geological Students’ Society. Currently, the library has a huge collection of journals, bulletins, technical reports, dissertation, text books and reference books of geological discipline. Students can utilize the collection of the library by spending time there doing their table works as it is equipped with computers, printers and inter-net facilities.

TU Central Library

Central Library of Tribhuvan University is the largest library in the country. It has extensive collection of books and periodicals of various disciplines. It offers facilities of reference corners, issuing corner, Nepal section, corners of journals and bulletins, and a corner for photocopying.

Students of geology may get benefit by spending their time in the Central Library, where corners having books and journal related to geology also exist.


Laborotories of Central Department of Geology

(a) Petrographic Laboratory:

The CDG has high equipped petrographic laboratory (Plates 2 and 3) 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.

(b) XRD Laboratory:

The XRD laboratory (Plate 4) 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 deletereous minerals. Identification clay minerals has several applications in discovering hydrocarbons, engineering constructions, environmental management, earthquake hazard management, agriculture and landuse planning, environmental interpretation.

(c) Engineering Geological Laboratory:

The Engineering Geological Laboratory (Plate 5) 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

(d) Geophysical Laboratory:

It is equipped with GPR, Terrameter, Seismic refraction survey instrument, etc.

(e) Laboratory of Ore microscopy:

This laboratory contains several specimens of ores, ore minerals and ore microscopes.

(f) Computer Room for GIS:

The Computer Room (Plate 6) is equipped with about 12 computers, one digitizer, one plotter, and various softwates such as Ilwis, Autocad, Corel draw, Arc View, Arc GIS and Dipts.

(g) Museum and specimens:

The museum of the CDG (Plate 7) 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.
