原位置において鉄と長期間接触させたクニゲルV1試料中の鉱物の変質挙動について調査した。その結果、生成量は微量であるものの、バーチェリン、鉄クロライト、鉄サポナイトが生成していることが推定され、また、鉄とクニゲルV1試料の接触界面に、石膏とカルサイトの生成が確認された。

Compacted bentonite (Kunigel V1) retrieved from the in-situ experiments in the ABM project was investigated to identify the mineralogical alteration of montmorillonite by iron-bentonite interaction in compacted bentonite. Berthierine, Fe-saponite and Fe-chlorite were found as the most possible alteration minerals of montmorillonite. Gypsum and calcite were identified at the contact surface between iron heater and compacted bentonite. These minerals were considered to be formed by the concentrating of salinity in the pore water of compacted bentonite due to the temperature gradient from iron heater.
