Development of technique in order to judge the activities of fault using chemical characteristics of active faults is useful for the assessment of faults at geological disposal sites. In this study, element transfer at fault gauge was examined. MnO contents were enriched at fault gauge of the Adera and Neodani faults. Most of Mn-bearing minerals are amorphous, it is suggested that Mn-bearing minerals were precipitated from reduced groundwater at oxidized condition when fault gauge were formed.

Development of technique in order to judge the activities of fault using chemical characteristics of active faults is useful for the assessment of faults at geological disposal sites. In this study, element transfer at fault gauge in Neodani fault was examined. Fault gauge were consist of khaki and dark-gray alteration of layer and brown layer. The origin of dark-gray and brown layers are mudstone, and MnO contents were enriched from the source rock to the fault gauge. It is suggested that Mn-bearing minerals were precipitated from reduced groundwater at oxidized condition when fault gauge were formed.

Tacit knowledge within an expert on the research on estimation of an uplift rate by using fluvial terrace as indicator was externalized by the knowledge engineering method. Sequences of the research and decision process during the investigation have been externalized as the "task flow" and "flow diagram of decision process", respectively, and the knowledge has been integrated into the expert system.
