Stratigraphy, Sedimentology and Paleoecology Lab

Stratigraphy, Sedimentology and Paleoecology
Science, 2nd Building
Research Activity
Our research group  is focused on the study of sediments and their textural and paleontological features
The four main expertises in this field are covered by the people in the lab.
  • Textural analysis of sediments
  • Stratigraphy and Biostratigraphy  (Cretaceous to Quaternary)
  • Ecology and paleoecology of benthic Foraminifera
  • Paleoclimatic and paleoceanographic meaning of Sapropels in the Mediterranean Sea

Ecology and paleoecology of benthic Foraminifera Biomineralization process in Foraminifera
Foraminifera are eukaryotic unicellular microorganisms inhabiting all marine environments. The study of these protists has huge potential implications and benefits. They are good indicators of global change and are also promising indicators of the environmental health of marine ecosystems. Much has still to be understood  about foraminiferal ecology. We have broad interest in the biodiversity, biogeography and ecology of modern benthic foraminifera and current research themes include  foraminiferal biodiversity, particularly on primitive foraminifera.  We have new interest in understanding the functioning mechanism behind biomineralization and the molecules involved. This help to understand the  biomineralization process in a geochemical perspective to record environmental and climate changes from shell isotopic and trace element compositions. Coupling geochemical and biological perspectives will enhance interpretation of the proxies used for climatic reconstructions and improve future modeling efforts.

Stratigraphy and Biostratigraphy (Cretaceous to Quaternary) Paleoclimatic and paleoceanographic meaning of Sapropels in the Mediterranean Sea
Stratigraphy is a branch of geology which studies  rock layers it  includes also biostratigraphy which principal aim is to date  sedimentary successions. Our team has a long tradition in biostratigraphic analysis for research and commercial purpose.
In the recent sedimentary history of the Mediterranean the deposition of organic carbon-rich layers corresponds to CO2 concentration peak. The sapropel seems to be a sedimentary response of the system,  which "buries" carbon on the sea floor. The study of these sediments therefore can be of great interest to understand the possible responses of the system to the current increase in CO2.

Terrigenous clastic sediments and sedimentary rocks are composed of fragments that result from the weathering and erosion of older rocks.  They are classified according to the sizes of clasts present and the composition of the material.  Texture is an important aspect in the description of sedimentary rocks and can be useful for interpreting the mechanisms and environments of deposition.
