Abstract

Abstract: The study of the paleomagnetic reversal and excursion events is not only one of the important methods to study the geodynamics, but also can ensure the framework of the paleomagnetic timescale more accurate. In this study, high resolution and multi-sets of parallel samples were collected in the Luochuan loess section. By detailed rock magnetism and paleomagnetic analysis, it can be conclude thatthe main magnetic carrier of L1, S1 in the Luochuan loess section is magnetite, and the hematite may also carry stable characteristic remanence in few samples. The Blake excursion event have been identified in the lower part of S1with an age of about (123±2) ka. Six subsets of parallel samples at 1 092~1 240 cm in S1 have also been measured. The paleomagnetic results show that the Luochuan loess might record the Blake excursion event,but the morphology within the polarity excursion is rather questionable. The Mono Lake and Laschamp geomagnetic excursion events have not been identified in L1. There are 3 samples at 175 cm can record an obvious geomagnetic anomaly. It can be considered that the geomagnetic anomaly can be compared with Hilina Pali/Tianchi geomagnetic excursion. In addition, the fact that one polarity event displays different morphology recorded in different regions in Chinese Loess Plateau may be caused by such several factors, as millennial scale depositional break in loess, low loess deposition rate, geographical location of different loess sections. Moreover, the reason why parallel samples from one section display different morphology may be lower relatively ancient magnetic field intensity which could reduce the alignment of magnetic carriers along the ancient geomagnetic field while dust deposition.

Key words: the last interglacial, Chinese loess, Luochuan section, polarity excursion, reliability, natural remanent magnetization, paleomagnetism
