Description:
Thermal Ionization Mass Spectrometry (TIMS) and Synchrotron X-Ray Fluoresence (SYXRF) are two methods for analyzing the isotope and trace element compositions of geological materials (e.g. rocks and fluids), in order to reconstruct their origin and history. We present several examples of how geological problems can be solved using these analytical methods: 1) age-dating of the oceanic crust beneath Gran Canaria (Canary Islands) using the Sm-Nd isotopic system, 2) tracing the origin of volcanic seamounts, ridges and ophiolites along the Pacific margin of Costa Rica with radiogenic isotope systems (Sr, Nd and Pb), 3) evaluating the role of seawater alteration on the composition of the oceanic crust using B isotopes, and 4) determining the input of halogens and other elements into the stratosphere during volcanic eruptions and assessing their effect on the ozone layer.
