Course description

The course provides the student with the tools to learn the basic knowledge on modern methods of integrated analysis that allow to reconstruct the trend of the climate in past eras through the use of paleontological data of both plant and animal origin, petrographic, geochemical(proxy data) . This educational approach is a key tool in the field of paleoclimatic and paleoenvironmental reconstructions for the definition of global climate and environmental change scenarios.

Prerequisites

no prerequisite.

Syllabus

PALEOCLIMATOLOGY - Climate and climate change; The climate system; Climate archives, data and models.
PLATE TECTONICS - Earth's heat flux and associated phenomena; It derives from the continents; classification of continental margins; expansion of the ocean floor; methods for measuring the spreading rate of the ocean floor; magnetic anomalies and their meaning, magnetostratigraphy; distribution of sedimentary cover on oceanic crust.
SEDIMENTARY ROCKS - Degradation of rocks, processes and mechanisms of transport and deposition. Composition, textures and sedimentary structures and their meaning. Diagenesis and lithification.
NOTES OF STRATIGRAPHY Stratigraphy principles; Main stratigraphic units. Absolute and relative chronology, scale of geological time. Sedimentary dynamics and notes on depositional environments.
EUSTATISM AND RELATIVE VARIATIONS OF SEA LEVEL.
CLIMATE CHANGES TO THE TECTONIC SCALE. CO2 and the long-term evolution of the climate. Plate tectonics and long-term changes in climate. The evolution of the climate from the Precambrian to the Quaternary. The Faint Young Sun Paradox. Climate model of the super continent Pangea; the tectonic control of CO2; the Blag hypotesis (spreading rate). The tectonic control on the removal of CO2, the uplift weathering hypotesis.

Learning assessment

The objective of the exam consists in verifying the level of achievement of the previously indicated training objectives.
The exam consists of an oral test in which the ability to describe link and compare different aspects treated during the course will be evaluated.
