METHODS AND APPLICATIONS
Sampling, preparation and studying techniques use the standard methods adopted for micropaleontology and are different for the diverse kind of microfossils investigated.
- Study of calcareous nannofossil assemblages consists in collecting tiny fragments of rock (about 3 cm3), preparing them as smear-slides and observing under optical polarizing microscope, both in cross and transmitted light, at 1250 magnification.
- Ostracods are extracted from disaggregated rocks (about 250 g) that are washed with H2O2, dried and analysed for the picking and observation of the species through a reflected and transmitted light microscope at 100 magnification.
- Data collected with quantitative and semi-quantitative methods prove to be a reliable and consistent dating tool, moreover allow observations on environment and climate changes.
The Micropaleontology Lab’s activity is precious for solving geological problems, in the Earth’s natural resource exploration, and for paleoclimatic studies.
Recently the Micro-Lab attends at the implementation of the “Micropaleontology Database” of Tuscan Region, and is involved in the Neo-Tethys e PALIS (Paleogene Integrated Stratigraphy). In the last years was involved in the Programma di Ricerca Scientifica di Rilevante Interesse Nazionale PRIN 2008 with the Research Unit of Pisa and PRIN 2010-2011 with the Research Unit of Padova. Moreover Micro-Lab have taken part to the project for the construction of the new geological map of Italy scale 1:50.000 (Project CARG)
Laboratory’s main scientific interests include biostratigraphic studies of sediments coming from different geological contests such as the sedimentary cover of Paleotethyan ophiolitic sequences, and the sedimentary successions outcropping in the Mediterranean and circum-Mediterranean orogenic belts; definition of biostratigraphic framework for the Cenozoic; analysis of the paleoclimatic significance of the calcareous nannoplancton and the response of calcareous nannoplancton to hyperthermals during the Paleogene. The Micropaleontology Laboratory is also interested in the stratigraphic reconstruction of Tuscan subsoil aimed to define the geometries of significant groundwaters. Moreover, in the laboratory, studies on biostratigraphy, ciclostratigraphy, paleoenvironment and paleobatimetry of Neogenic-Quaternary costal sediments have been carried out for a long time.
