Geology Museum

Location: Old Building First Floor

Telephone Extension:

The Geology Museum of the Department is small, but has an excellent collection of minerals, rocks, gems and fossils. A primary role of the museum is to illustrate the diversity of the geology and mineral resources of Sri Lanka. It includes an extensive collection of specimens of many mineral varieties and rocks including gemstones. It serves as a teaching resource for university students and school children as well as the general public.

The main sections of the museum are Mineral Gallery, Rock collection with different examples of igneous, metamorphic, sedimentary rocks, Sri Lankan Gem Collection; Sri Lankan Rock Collection and many more.

Visitors also can touch a real meteorite which is the only recorded meteorite in Sri Lanka.

The Geology Museum welcomes groups of all kinds, particularly school groups of all ages. The museum offers short educational programs for school students that include a short lectureon minerals, rocks and mineral identification.

To arrange special tours conducted by staff members of the Department of Geology and please call the Geology Office at (081) 2394200.

The Museum is open to the public from 9:00 a.m. to 4:00 p.m. Monday through Friday and at other times by special prior arrangement.

Scanning Electron Microscope (SEM) Facility

Location: South Wing - Ground Floor

Telephone Extension:

The Geology Department houses a Zeiss EVO LS15 high-performance, Variable Pressure Environmental Scanning Electron Microscope with an EDX (Energy Dispersive System). The low vacuum mode, allows for observation of specimens which cannot be viewed at high vacuum due to excessive water content or due to a non-conductive surface.

The SEM facilities are available for use by both members of the university and external users.

For SEM booking, please contact Mr. DanushkaGamage (Tele: xxxx; Email: xxxx)
