The petrology and mineralogy laboratory provides support services and research facilities to SGS technical projects and other government institutions, the private sector, and the communities in various fields of sample preparation and their petrologic and mineralogical analyses, including their analysis using scanning electron microscopy (SEM) and X-ray diffraction analyses (XRD).

The Petrology-Mineralogy Laboratory are maintained under the supervision of three technical units. Its work processes comply with international standards, and it efficiently operates with qualified technicians and highly trained staff.

Sample preparation

Rock, mineral, and ore samples are prepared into their suitable media, such as thin sections, polished sections, stained thin sections, stained slabs, polished mounts, and polished slabs by sawing, grinding, lapping, thin sectioning, and polishing, before they are analyzed under the microscope, among other analytical techniques. The slabs are also cut into aesthetically designed slabs using a water-jet machine.

Microscopic Studies

Optical microscopes use transmitted light and reflected light microscopy in analyzing non-opaque and opaque minerals (Fig. 1). The laboratory is also equipped with scanning electron microscope (SEM) to conduct nondestructive micro-chemical analyses (spot analyses), elemental mapping, and line-scan for solids (Fig. 2). It measures the abundance of elements from beryllium (4) to uranium (92) using energy dispersive spectroscopy (EDS) and wavelength dispersive spectroscopy (WDS), which provide the elemental compositions of wide variety of materials, including rocks, minerals, ores, metals, alloys, ceramics, etc. The SEM can also produce high-resolution electron images using both secondary electron (SE) and backscattered electron (BSE) that provide information about the topography, morphology, and micro-textural features of the analyzed materials.

X-Ray Diffraction analysis

The X-ray diffractometer (Figure 3) is used in the precise determination of the different mineral constituents of solid Earth materials, such as rocks and sediments. A comprehensive x-ray diffraction analysis with interpretations can be provided by the laboratory.
