Project IC8_I: Magnetic minerals as markers of coastal zone evolution

Magnetic minerals are abundant in estuarine, coastal and shelf environments. A number of environmental processes imprint specific changes onto the composition, grain size and concentration of the magnetic mineral assemblage, which can be quantified at high sensitivity. Sedimentary magnetic minerals thus have an excellent potential as markers of sediment provenance, dynamics, diagenesis and pollution in coastal and shelf environments.
