23. O and H isotopes used to evaluate juvenile vs. meteoric vs. brine characteristics of water and the type of water responsible for rock alteration
d18O is quite different for mantle rocks and surface-reworked sediments, so it may be used to evaluate the extent to which mantle-derived magmas are contaminated by crustal sediments
Thermometry of minerals?
Beware of re-equilibration and alteration!
