Geophysical exploration of archaeological sites has
been a successful tool becoming more and more popular in the last
decades. Many archaeological features can be detected with magnetic
gradiometry (MGR), such as fire places, burned loam, metal artifacts, or
other remnants, which produce a remanent magnetic signal detectable on
the surface. However, as magnetic minerals are also present in natural
settings, e.g. sedimentary and magmatic rocks and sediments derived from
these host rocks, the MGR signal from archaeological artifacts is often
embedded in a broader geomorphological signal, which makes separation
of the different sources difficult. We provide geophysical data from two
complex archaeological sites in northern Germany, which have been
obtained with different methods, e.g. magnetic gradiometry (MGR),
electrical resistivity tomography (ERT), electro-magnetic mapping (EM),
and ground-penetrating radar (GPR). The combination of geophysical
methods maps different material properties of both the geomorphological
and the archaeological sources. We then use the three-dimensional
modeling tool PREDICTOR to analyze the sources for the geophysical
signals, e.g. the dominant signal in Leimbach, resulting from infill of
palaeo-channels in the settlement area, and fire places as well as
shafts in the hill fort of Lossow. The model prediction enables us to
quantify the structures in the sub-surface and therefore helps to
unravel complex situations often present in archaeological excavations.
