Research into layered intrusions at Duke University has
been concentrated in a number of directions. These include
the following:
-
Halogen geochemistry of layered intrusions and the role
of volatile fluids during the crystallization of layered
intrusions
-
Textural evolution of cumulate rocks, crystal size distributions
studies and quantitative modeling of crystal aging..
-
Stable Cl isotopes and the origin of high-Cl parent magmas.
-
Quantitative modeling of compaction and liquid infiltration-reaction
in solidifying crystal piles.
