Paleomagnetism‐Based Chronology of Holocene Lava Flows at Mt Ruapehu, Aotearoa New Zealand
Geochemistry, Geophysics, Geosystems, Volume 25, Issue 9, September 2024.Abstract Dating young lava flows is essential for understanding volcano's eruption frequency, yet challenging due to methodological limitations of commonly used dating techniques. Ruapehu (Aotearoa New Zealand) produced many lava flows during the Holocene, but constraints on the timing of these eruptions are scarce. Here, we use paleomagnetic dating to

Holocene eruptive history of the Stromboli volcano: Constraints from paleomagnetic dating
, 2008 We report on paleomagnetic directions gathered from 33 sites from (mostly Holocene) volcanics from Stromboli, loosely dated at present by few K/Ar and 14C ages.

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 7, July 2024.Abstract Geomagnetic field models over past millennia rely on two main data sources: archeomagnetic data provide snapshots of the geomagnetic field at specific locations, and sediment records deliver time series of the geomagnetic field at specific locations.

Local Magnetic Anomalies Explain Bias in Paleomagnetic Data: Consequences for Sampling
Geochemistry, Geophysics, Geosystems, Volume 25, Issue 5, May 2024.Abstract Volcanic rocks are considered reliable recorders of past changes in the Earth's magnetic field. Recent flows, however, sometimes fail to produce the known magnetic field at the time of cooling. Previous research on Mt. Etna suggests paleomagnetic data might not be accurately recorded.

Revisiting the chronology of the Early Iron Age in the north-eastern Iberian Peninsula
, 2019 International audienceThe chronology of the Late Bronze Age and the earliest stages of the Iron Age in the Mediterranean is an important topic of debate since the study of both local social dynamics and trade and colonial activity around the ...
