In the laboratory is carried out a number of special methods serving for an isolation of varied microfossils from sediments of different geological age.
- 501 – Laboratory processing of palynological samples
- 504 – Washing of micropaleontological samples
- 506 – Laboratory processing of nanoplanckton samples
- 507 – Special works (development of new methodicstechniques)
- 508 – Laboratory processing of others micropaleontological samples (accordingly to previous agreement)
- 509 – Biostratigraphic analysis
Basic principle of the method 501 is palynological maceration: it is a set of different very specialized methods for an isolation of acido- resistant palynomorphs (plankton, spores, pollen etc.) from sediments. Methods differ of each other according to a geological age of processed samples (Older lower Paleozoic – Quaternary).
The method 506 serves for isolation of calcic calcareous nanoplancktons (Cretaceous – Tertiary), the method 504 for isolation of foraminifera’s and others fossils by washing of the friable sediment (Cretaceous – Tertiary) through sieves.
Methods 507, 508 include chemical extraction of microfossils (conodonts, micro vertebrata microvertebrate remains and brachiopods) from rocks, faurther processing of residues (sieving, heavy liquid separation) and isolation of macrofossils from residues.
The method 509 offers a scientific elaboration of certain groups of microfossils by individual specialists for taxonomic and biostratigraphic purposes.
