This session will be dedicated to the description and analysis of palaeosecular variation and paleointensity data sets recently acquired, or updated, from baked Earth series, lava flows series and sediments series. The scope of the session will comprise past geomagnetic field structures, construction of correlation arrays for sediment sequences and establishment of high resolution chronologies for historical and prehistorical times. Temporally highly resolved palaeomagnetic secular variation records became during the last years increasingly available from a wide range of geo-archives and archaeological materials. These records may contribute to a better understanding of the geodynamo and may provide a precise and independent dating tool covering the interval from historical times to the recent geological past. Quasi continuous temporal resolution on sub-millennial timescales can be achieved even in archives like loess or colluvial sediments which may provide new directional data from previously poorly covered geographic regions. Baked clays and lavas, however, yield snapshots of the Earth’s magnetic palaeofield and allow for precise PSV records in direction and intensity. They are capable for recording even archaeomagnetic jerks from the short end of the secular variation time scale as well as geomagnetic excursions. The session will be open for PSV records from all kind of archives. However, data sets from poorly covered regions (Southern hemisphere, Pacific region) as well as from the recent geological past with an age control by numerical dating or correlation to independently dated proxy records are especially welcomed.
