The linear fractures are developed extensively in northern Ningdu county,central Jiangxi province. Based on landset-7 ETM+RGB synthesis image,the author interpreted out four groups of linear fractures,namely, NE-,NNE-,NW-,and a few of EW-trending faults. All of them showed a distinct traces of neotectonism with evidence from strike-slippinp of faults,earthquakes,hot springs, etc. The NE-striking Taoshan fault,developed in the dike-structure belt in neotectonism period,was a dextral transtensile one with SE-dipping at 65°～70°,with the southeast block downsliding and tear faulting occurring,so that the upper plate of the fault,especially its northeast part,was relatively weaker eroded. There might be a good ore-protecting conditions and more prospecting potential in those regions for uranium ore exploring.
