Initial measurements are reported on the extended x-ray-absorption fine structure (EXAFS) of the Fe K edge in FeS2 to 64 kbar and FeF2 to 21 kbar. With this new technique the Fe-Fe spacings are directly observed to vary in accordance with high-pressure x-ray diffraction measurements of the corresponding lattice parameters. In contrast, the Fe-S spacing in pyrite is found to be much less compressible. Pressure reduction of the mean-square deviations in the iron-ligand bond lengths are also given.
