Most evaluations of those fluid conducting features and contaminant migration processes have been conducted mainly by the present hydrological characteristic of fractures for deep underground usages (e.g., for high level radioactive waste (HLW) disposal, LPG and C02 storage). In the orogenic field of Japan, there are wide areas of crystalline rock. The rocks in each area have a distinctive history which is partly reflected in the characteristics of the fracture systems and associated mineral fillings that occur. The structural and mineralogical features readily illustrate how certain contaminants might react and be retarded by the fracture fillings and open pore geometry, due to chemical sorption and/or physical retardation. The work reported here seeks to provide geological evidence that natural long-term physical and chemical processes are unlikely to change the overall transport and retardation properties of the rock significantly., 地下深部の環境ならびに物質循環を理解するためには、透水性割れ目の産状とそこでの岩石-地下水反応を理解することが不可欠である。そのための1つのアプローチとして、透水性割れ目に見られる充填鉱物に着目した研究を進めている。これまでの研究結果から、透水性割れ目には炭酸塩鉱物(カルサイト)が充填していることが認められた。本論では、その産状と形成プロセスについての概要を述べる。, 名古屋大学年代測定総合研究センターシンポジウム報告}, pages = {54--56}, title = {深部花崗岩中の透水性割れ目と充填鉱物 : 産状と形成プロセス}, volume = {23}, year = {2012} }
