Description of equipment

The 508 PV UV-Visible-NIR microscope spectrophotometer from CRAIC Technologies (USA) with accessories (standards, computer, software) is an add-on to the existing Zeiss-Opton transmission, reflectance and fluorescence microscope. The equipment is intended for the study of organic matter (coals, kerogen, organic-rich rocks). The spectrophotometer is further used for the determination of fluorescent components in organic matter. These components include residues of algae, spores, pollen, cuticles, cork, resins and waxes. They are subordinate in coals and enriched in the organic matter of the source rocks for the formation of hydrocarbons, especially petroleum. They are collectively known as kerogen I and kerogen II. Rocks containing organic matter with kerogen I and/or II are abundant in the world, and are also known here in various stratigraphic units. They are black, formed in marine environments, and can be the carriers of various geochemical anomalies or even weathering. Some, also known in this country, are highly radioactive. Hydrocarbons are formed from the different types of kerogen only if the organic matter reaches a certain maturity range (oil from kerogen I and/or II in the Rr vitrinite range of 0,5-1,35 and gas from kerogen III in the Rr vitrinite range of 0,9-3,0), which is measured by the method described in the first paragraph. The fluorescence intensity in the different colours (yellow, orange green, brown) is also measured and decreases with the maturity of the organic matter. The vitrinite reflectance method is further used in the study of the tectonically driven thermal history of sedimentary basins.

The equipment is designed for the study of organic matter (coals, kerogen, organic-rich rocks). The spectrophotometer is further used for the determination of fluorescent compounds in organic matter. These components include residues of algae, spores, pollen, cuticles, cork, resins and waxes. They are subordinate in coals and enriched in the organic matter of the source rocks for the formation of hydrocarbons, especially petroleum. We can also measure the fluorescence intensity in different colours (yellow, orange green, brown), which decreases with the maturity of the organic matter. The vitrinite reflectance method is further applied to the study of the tectonically driven thermal history of sedimentary basins.

Equipment rental

The equipment is intended for use by GeoZS researchers and, by arrangement, by researchers from related institutions who are proficient in optical microscopy. The price is determined by the internal price list of the GeoZS or by agreement.
