dc.description.abstractWe report Rb---Sr, Sm---Nd and mineralogical data for leached whole rock, 87Sr/86Sr from 0.708 to 0.711 in exchangeable sites. Leached authigenic illite from the 1200 m, independent of the duration of burial. The exchangeable Sr in the clay has remained an open system and has undergone isotopic exchange since that time. Minimum fluid/rock ratios of 0.2 to 2 are modeled from Sr isotopic data, consistent with rock-dominated, open system diagenesis. Leachates and residues of the 147Sm/144Nd ( 147Sm/144Nd as high as 0.188. This Sm/Nd fractionation, in conjunction with the preserved isotopic equilibrium may be useful for dating diagenesis and associated fluid-rock interaction in older rocks.en_US
