¹⁰ Be Indicator for the Matuyama‐Gauss Magnetic Polarity Reversal From Chinese Loess

The Matuyama-Gauss (M-G) magnetic polarity reversal is regarded as a fundamental time marker in the stratigraphic division of Quaternary-Neogene. However, previous paleomagnetic studies have shown that M-G mainly recorded Chinese loess unit L33—a glacial stage (corresponding to marine isotope 104, i.e., MIS 104)—which asynchronous with timing sediments. Here, we solve this long-standing debate by exploiting method extract reproducible records field intensity from Xifeng and Lantian profiles meteoric 10Be. results showed for both profiles, 10Be-derived boundary located paleosol S32 ca. 2,589 ± 3 ka, which corresponds 103. This synchronous seen sediments, though it is, on average, ∼19 ka younger than inferred measurements two demonstrates overprinting has occurred.
