The increase in the magnetism caused by these features results from the cumulative contribution of both thermoremanence and induced magnetism, formed through different processes (Tauxe 2002) which (in this case) result from human activity.
Thermoremanence is acquired when iron oxide-rich materials (such as clay) are heated above the Curie point (578[degrees]C for magnetite and 578-675[degrees]C for maghemite; Schmidt 2007: 23), when the iron minerals are demagnetised then remagnetised en-masse in line with the earth's magnetic field when they cool (Clark 1990: 65).
Recently, Dekkers & Bohnel (2006) proposed a new method for palaeointensity determinations, which they termed the "multi-specimen parallel differential partial thermoremanence" method (hereby labelled MPDM).
