Abstract
The objective of this project is to characterize the texture and mineralogy of mantle xenoliths form SE Brazil, with special emphasis on the geochemistry of major and trace-elements of the main minerals (olivine, clino- and orthopyroxene, phlogopite and chrome-spinel) through detailed petrographic studies and analyses by WDS-Electron Microprobe and Laser-Ablation ICPMS. The samples select…
