Eocene-Oligocene continental sediment natural gamma radiation data of the CDB1 drill-core (Rennes Basin, France)

The natural gamma radiation (NGR) data were acquired each 10 cm (see details below) on fluvio-lacustrine and palustrine sediment materials, from the continental CDB1 drill-core located in the Rennes Basin (Chartres de Bretagne, France, geographic coordinates: 48.04412074N; 1.71899076W, Elevation: +37m NGF, Nivellement Général de France). The studied geological time interval covers the Eocene-Oligocene transition interval, roughly from 31 to 38.5 Ma. […]自然伽马辐射（Natural Gamma Radiation，NGR）数据以每10厘米的采样间距采集（详细信息见下文），采集载体为法国雷恩盆地（布列塔尼沙特尔地区）大陆CDB1钻孔的河湖相与沼泽相沉积物质。该钻孔的地理坐标为北纬48.04412074°、西经1.71899076°，海拔为+37米（NGF，即法国国家高程基准Nivellement Général de France）。本次研究的地质时间跨度覆盖始新世-渐新世过渡时段，大致为31至38.5百万年前。[……]
