| 摘 要： | 借助我国黄土磁化率与温度关系的研究成果,根据河北省沉积岩地层的磁化率数据,初步建立了自晚元古代以来河北地区的古温度变化序列,但认为这种古温度序列的精度较差;提出了建立自晚元古代以来各地史时期高精度古温度变化序列的方法。 |

| Abstract: | According to the relationship between loess magnetic susceptibility and paleotemperature, this paper has set up a paleotemperature sequence from Proterozoic to Quaternary based on sedimentary susceptibility in Hebei province, in which the apparent temperature is 9℃ in Quaternary, 12℃ in Jurassic, 5℃～7℃ in any other period. Nevertheless, the author consider that the paleotemperature sequence is of low precision, and hence put forward a method for reconstructing a high accuracy paleotemperature sequence from Proterozoic up till now. |
| Keywords: | Hebei Province sedimentary magnetic susceptibility paleotemperature sequence |
