| 摘 要： | INTRODUCTIONFuzhou basin is a faulted basin developed during the mid-late Quaternary,filled with marine ,terrestrial and alternating marine-terrestrial facies sediments (Lin,1979 ;Lan,et al .,1986 ; Han,etal .,1992 ;Ding,et al .,1992 ; Wang,et al .,2000 ; Wang,et al .,2002) .Inthe basin,concealedfaults are distributed. With the support of a project entitled“Testing exploration of active fault inurban area”of the National Development and ReformCommission,two drill holes (SZK1 and S…

| Abstract: | Based on the content of radioactive elements (U, Th, K) of strata in two drill holes in the Fuzhou basin, and combined with the result of spore_pollen analysis, the relationship between radioactivity and lithology and deposit environments is discussed and the results show that the content of radioactive substances is related to the granularity and lithology in sediment, and it is higher in argillaceous sediment (e.g. silt and clay), lower in sand sediment and in the middle in gravels between the above two kinds of sediment. The content of radioactive substances is also related to paleoclimate. A warm and humid environment is propitious to the deposition of radioactive substances, while a cool and dry climate is just the reverse. |
