Moduli

Metodi di valutazione

Modalita' di verifica dell'apprendimento: 

Assessment method
Written and Oral examination

Written: 20 questions to be briefly answered in 90 minutes.

Each answer is given a mark. No answer counts 0. Final mark is the mean.

The first question, exclusively for the students of Geological Sciences who select this course, is aimed at assessing their knowledge of the main subdivision of the geological time. A negative result for this first question corresponds to immediate rejection.

Oral: questions about the written results.

The final mark is composed by the written+oral marks plus up to 1 point for the practicals.

Marks are given as n/30. Minimum positive value is 18/30

Obiettivi formativi

Aims
To provide the main concepts for understanding the interactions and the coevolution of biosphere, hydrosphere and geosphere.

To acquire the conceptual and operative knowledge for the study and interpretation of the modern marine environments and their reconstruction in the geological record, including the recent past.

Contenuti

Contents
Coevolution of geosphere and biosphere, principles of biomineralization, biogenic carbonates, bioconstruction and habitat engineers, sediments and benthos, benthic zonation, introductory biogeochemistry and proxy data in natural archives, past and ongoing global changes

Programma esteso

Detailed program
Lessons: The benthos in the geologic history. Extinctions and major events in the Earth history. The appearance of organic calcification and the biomineralization. Photosynthesis and chemosynthesis. Ocean chemistry and biomineralization. The evolution of biogenic builders in the Phanerozoic. The modern bioconstruction: structures, biological associations, ecological factors of control and distribution. Habitat engineers. Diagnosis, significance and distribution of the major benthic associations and related sediments. Benthic zonation in the present-day oceans as key to understand the geological record. The benthos in the geomorphology and evolution of carbonate platforms. Biocoenoses, communities, associations and interpretation of fossil assemblages on the basis of the biostratinomic processes. The chemical environment at the water-sediment interface. Identification and interpretation of the most important ichnofacies. Biogeochemical proxies and natural archives. The ongoing global change and the geobiological feed-back.

Laboratory. Geobiological analyses of carbonate sediments and fossil–bearing material and their interpretation.
