For decades the Holocene has been considered a flat and boring epoch from the standpoint of
paleomagnetism, mainly due to insufficient resolution of the available paleomagnetic data. However, recent
archaeomagnetic data have revealed that the Holocene geomagnetic field is anything but stable – presenting
puzzling intervals of extreme decadal-scale fluctuations and unexpected departures from a simple dipolar field
structure. This new information introduced an entirely new paradigm to the study of the geomagnetic field and
to a wide range of research areas relying on paleomagnetic data, such as geochronology, climate research, and
geodynamo exploration.
This proposal aims at breaking the resolution limits in paleomagnetism, and providing a continuous
time series of the geomagnetic field vector throughout the Holocene at decadal resolution and
unprecedented accuracy. To this end I will use an innovative assemblage of data sources, jointly unique to
the Levant, including rare archaeological finds, annual laminated stalagmites, varved sediments, and arid
playa deposits. Together, these sources can provide unprecedented yearly resolution, whereby the absolute
archaeomagnetic data can calibrate relative terrestrial data.
The geomagnetic data will define an innovative absolute geomagnetic chronology that will be used to
synchronize cosmogenic 10Be data and an extensive body of paleo-climatic indicators. With these in hand, I
will address four ground-breaking problems:
I) Chronology: Developing dating technique for resolving critical controversies in Levantine archaeology and
Quaternary geology.
II) Geophysics: Exploring fine-scale geodynamo features in Earth’s core from new generations of global
geomagnetic models.
III) Cosmogenics: Correlating fast geomagnetic variations with cosmogenic isotope production rate.
IV) Climate: Testing one of the most challenging controversial questions in geomagnetism: Does the Earth's
magnetic field play a role in climate changes?
