摘　　要：为推动中国高放废物地质处置研发和为将来处置库岩性比选提供基础,“十二五”粘土岩处置库区域调查和地段筛选,确认塔木素预选地段地质条件稳点,存在埋深适中、连续厚度大、分布面积广的粘土岩(泥岩)层位。地段泥岩为“白云石方沸石泥岩”,主要矿物方沸石和粘土岩矿物对放射性核素具有较强的吸附能力。从地质、社会经济和建造工程条件、泥岩性能方面初步评价研究可知,塔木素预选地段非常适宜作为高放废物地质处置库场址预选地段。In order to promote the research and development of HLW geological disposal in China and provide a basis for future lithological comparison and final site confirmation of HLW Geological Disposal Repository,this paper selected and analyzed the pre-selected region of HLW Repository in clay confirmed the stability of the geological conditions of the pre-selected area of Tamsu in which the fault tectonic activity is weak.There are clay stone layers with moderate burial depth,large continuous thickness and wide distribution area.The clay stone in the area is“dolomite analcite clay”.The main minerals analcite and clay minerals have strong adsorption capacity for radionuclides.From the geological,socioeconomic,construction engineering conditions,and preliminary evaluation of clay performance,it can be seen that the pre-selected area of Tamsu is very suitable for the HLW geological disposal.
