PPT-Stable Isotope Geochemistry

Stable isotopes are used in CCS to look for leakage of CO2 into overlying aquifers or into the surface environment What are Stable Isotopes These are isotope that do not decay over time as the radiogenic isotope do.

Isotopes are atoms that have the same number of protons but different numbers of neutrons. Most elements in the first two rows of the periodic table have at least 2 isotopes with one being more common than the other. Lecture 30 . Beginnings.

COMMON plumeswere initially thought to consist of primitive mantle (e.g., Schilling, 1973). As we found, mixing be-tween primitive and depleted mantle can explain the Sr and Nd isotopic compositions Prosper Zigah. Woods Hole Oceanographic Institution. pzigah@whoi.edu. 1. What are Isotopes.
