FWF - Charon II - Mechanisms controlling the formation and diagenetic alteration of carbonates

Project: Research project

Description

Carbonates are the most important rock type for reconstructing the Earth System with respect to the physical and chemical evolution of the oceans as well as changes in atmospheric composition and global climate. The evolution of the climatic and physico-chemical parameters on Earth's continents and in the oceans throughout Earth history can be reconstructed by analysing marine and continental carbonate archive proxies including isotopes and elemental ratios.
Carbonates, however, are subject to variable degrees of post-depositional diagenetic alteration. Diagenesis represents the single most significant obstacle in the use of carbonate archive research. The interpretation of individual proxy data sets from carbonate archives requires a detailed understanding on the distribution behavior of elements and isotopes during the formation of carbonates. To the present day, however, many of the underlying processes are insufficiently understood. The present study is based on experimental approaches for the (trans)formation of amorphous and crystalline carbonates at low and elevated temperatures to obtain a deeper understanding of underlying reaction mechanisms and pathways.
