Magnetostratigraphy and its paleoclimatic significance of the PL02 borehole in the Yinchuan Basin

摘要

The basin sediment provides an important means of studying regional tectonic actives; however, regional climate factors, overlaying tectonic actives, affect the sedimentary process in the basin. Because of the lack of long-term scales data, the research on climate change in the arid and semi-arid region is limited. The PL02 core, located in the center area of deposition in the Yinchuan Basin; has a thick deposit with a higher resolution and sedimentation rate, making itself practical for the reconstruction of the paleoclimate and the coupling relationship between regional tectonic activities and climate change.
