英文摘要 | A simple model for reconstructing the paleomagnetic field intensity with (10)be production rate was used for the first time in loess (10)be studies of luochuan profile. using the lgm (last glacial maxmium) method, the climatic effects and geomagnetic modulation effects on loess (10)be was separated and in turn the 80 ka geomagnetic excursion sequence reconstructed, of which the globally remarkable geomagnetic excursion events such as the laschamp (42 ka), mono lake (32 ka) during the last glacial period were revealed and the paleo-geomagnetic intensity curve from loess (10)be over the past 80 ka was quantitatively reconstructed. the reconstructed paleo-intensity fits well with the paleo-intensity curves (sint200 and napis75), which indicates the significance of global criterion of the (10)be paleo-intensity curve and the future direction of loess (10)be tracing studies. results show the irregular variability of the east asian monsoon precipitation in loess plateau is the main cause that has resulted in the ambiguity of the geomagnetic modulation of the (10)be record in the loess, and the intrinsic source component of the loess (10)be and inherited fraction of magnetic susceptibility (sus) are characterized by the "quasi-homogeneous distribution" manner. |
