We perform chemical analysis of various type of material such as rocks, soils, sediments, water. Sedisor is specialised in isotope composition analyses using radiogenic isotopes and stable isotopes. This academic research institute, located next to the French Ifremer Institute is one the most recognized French research institute in marine Science. Sedisor benefits every day from collaborations and interactive relationships with academic researchers in all fields. Her main field of expertise are: Magmatic geochemistry using major-trace elements and radiogenic isotopes to study the petrogenesis and deep sources of geological materials Sedimentary geochemistry: Sediment provenance investigations using Source to Sink approaches Isotope stratigraphy and geochronology Sr Isotope stratigraphy and geochronology Pollution investigations using Pb isotopes. SEDISOR offers analysis and expertise services in geochemistry of elements and isotope geochemistry: concentration measurements at different levels major, minor, trace and ultra-trace on inorganic matrices; composition measurements of radiogenic isotopes and metal. Concentrations Analyses.

On going collaborative Research. S2S : Sediment provenance studies We participate to several academic research projects to determine the geographical origin of sediments in a Source To Sink approach.
Geochronology is the science of determining the age of rocks, fossils, and sediments using signatures inherent in the rocks themselves. Absolute geochronology can be accomplished through radioactive isotopes, whereas relative geochronology is provided by tools such as palaeomagnetism and stable isotope archotelzeeland.com combining multiple geochronological (and .

Sep 01, An important assumption that we have to be able to make when using isotopic dating is that when the rock formed none of the daughter isotope was present (e.g., 40 Ar in the case of the K-Ar method). A clastic sedimentary rock is made up of older rock and mineral fragments, and when the rock forms it is almost certain that all of the fragments Author: Steven Earle. Sediment dating with Cs This technique exploits the injection of radioisotopes into the atmosphere, which occurred during atmospheric nuclear testing, mainly in the late s and mid s. It uses this injection as a marker to identify soil and sediment particles laid .
